ZEISS Xradia 410 VersaSubmicron X-ray Imaging: Bridge the Gap in Lab-based MicroscopyProduct Information Version 1.1Xradia 410 Versa bridges the gap between high-performing X-ray microscopes and less powerful, lower-cost computed tomography (CT) systems. Delivering non-destructive 3D imaging with industry best resolution, contrast, and in situ capabilities, Xradia 410 Versa enables you to achieve groundbreaking research for the widest range of sample sizes. Enhance imaging workflow with this powerful, cost-efficient "workhorse" solution, even in diverse lab environments.A Workhorse Solution for Your 3D Submicron Imaging› In Brief › The Advantages › The Applications › The System› Technology and Details › ServiceSimpler. More Intelligent. More Integrated.Extend the Boundaries of ScienceXradia 410 Versa X-ray microscope delivers cost-efficient, flexible 3D imaging to enable you to address a wide range of samples and research environments. Non-destructive X-ray imaging preserves and extends the use of your valuable samples over time. The instrument achieves0.9 μm true spatial resolution with minimum achievable voxel size of 100 nm. Advanced absorption and phase contrast (for soft orlow-Z materials) offer you more versatility to overcome the limitations of traditional computed tomography approaches.Your Premier 4D / In Situ SolutionNon-destructive X-ray microscopes allow youto uniquely characterize the microstructure ofmaterials in their native environments—in situ—as well as to understand the evolution of proper-ties over time (4D). RaaD capabilities enableyou to maintain submicron resolution across abroad spectrum of sample dimensions in nativeenviron m ents and to use a wide range of in siturigs. The Xradia Versa In Situ Kit makes set-upoptimal and operation easy with a faster timeto results.Achieve Performance Beyond Micro-CTXradia Versa solutions extend scientific researchbeyond the limits of projection-based micro- andnano-CT systems. Where traditional tomographyrelies on a single stage of geometric magnifica-tion, Xradia 410 Versa features a unique two-stage process based on synchrotron-caliber optics.You will find it easy to use, with flexible contrast,while its breakthrough Resolution at a Distance(RaaD) enables you to achieve unprece d entedlab-based exploration for a diverse array ofapplications, sample types and sizes.

ZEISS XRM are specified on true spatial resolution, the most meaningful measurement of a microscope’s performance.Spatial resolution refers to the minimum separation at which you can resolve a feature pair with an imaging system. It is typically measured by imaging astandardized resolution target with progressively smaller line-space pairs. Spatial resolution accounts for critical characteristics such as X-ray source spot size, detector resolution, magnification geometry, and vibrational, electrical and thermal stability. Other terms such as “voxel,” “spot size,” "detail detectability," and “nominal resolution” do not provide you with an understanding of full system performance.› In Brief› The Advantages › The Applications › The System› Technology and Details › ServiceYour Insight into the Technology Behind ItAn Edge In ContrastYou require superior contrast capabilities to reveal details needed to visualize and quantify features. Xradia Versa deliver flexible, high contrast imaging for even your most challenging materials – low atomic number (low Z) materials, soft tissue, polymers, fossilized organisms encased in amber, and other materials of low contrast.Our comprehensive approach employs proprietary Enhanced Absorption ContrastDetectors that achieve superior contrast by maximizing collection of low energy photons while minimizing collection of contrast-reducing high energy photons. In addition, Tunable Propagation Phase Contrast measures the refraction of X-ray photons at material transitions to allow you to visualize features displaying little or no contrast during absorption imaging.Pear imaged with absorption contrast – no visibility of cell walls (left), and pear imaged with phase contrast, showing details ofcell walls in normal cells and stone cells (right).› In Brief› The Advantages› The Applications› The System› Technology and Details › ServiceTailored Precisely to Your Applications› The Advantages› The Applications› The System› Technology and Details› ServiceLarge flip chip (10x10x1 mm) imaged at high resolutionUnstained water in Ottawa sand, imaged in a 12.5 mm diameter aluminum tubeComposite material of polyurethane, EDPM, metal oxides and high melting explosiveMurine breast tissueZEISS Xradia 410 Versa at WorkNatural Resources Materials ResearchElectronicsLife Sciences125 µm5 mm0.7 mm1 mm› In Brief › The Advantages › The Applications › The System› Technology and Details › Service1211910768354Your Flexible Imaging Solution4 System Stability for Best Imaging • Granite base vibrational isolation • Thermal environment stabilization • Low noise detector• Proprietary stabilization mechanisms5 System Flexibility for Diverse Range of Sample Sizes• Variable scanning geometry • Tunable voxel sizes• Absorption contrast mode • Phase contrast mode• Wide Field Mode (WFM) for increased lateral tomography volume with 0.4X objective• Vertical Stitching for joining multiple tomographies vertically6 Autoloader Option• Maximize productivity by reducing user intervention • Programmable handling of up to 14 samples• Automated workflows for high volume, repetitive scanning7 Sample Stage• Ultra-high precision 8-degrees of freedom sample stage 15 kg sample mass capacity8 X-ray Filters • Single filter holder• Set of 12 filters included• Custom filters available by special order 9 In Situ and 4D Solutions• Resolution at a Distance (RaaD) enables superior in situ imaging • I ntegrated in situ recipe control for Deben stages • In situ interface kit option • Custom in situ flow interface kit by special order 10 Instrument Workstation• Power workstation with fast reconstruction • Single CUDA-based GPU • Multi-core CPU • 24” display monitor11 Software• Acquisition: Scout-and-Scan Control System • Reconstruction: XMReconstructor • Viewer: XM3DViewer• Compatible with wide range of 3D viewers and analysis software programs• ORS Visual SI for 3D visualization and analysis (optional)1 X-ray Microscope• ZEISS Xradia 410 Versa with Resolution at a Distance 2 Source Options• Light materials, closed reflection source (20 – 90 kV, maximum 8 W)• High energy, closed reflection source (40 – 150 kV, maximum 10 W)• High power, closed reflection source (40 – 150 kV, maximum 30 W)3 Contrast-optimized Detectors• Innovative dual-stage detector system with detector turret of multiple objectives at different magnifications with optimized scintillators for highest contrast• 2k x 2k pixel, noise suppressed charge-coupled detector› In Brief › The Advantages › The Applications › The System› Technology and Details › ServiceTechnical Specifications› In Brief› The Advantages› The Applications› The System› Technology and Details› ServiceBecause the ZEISS microscope system is one of your most important tools, we make sure it is always ready to perform.

TURNING PAST THIS STOP WILL DAMAGE THE SENSOR.SHORT CIRCUIT PROTECTION WILL AUTOMATICALLY RESET ONCE SHORT IS REMOVED.IntroductionA diffuse reflective sensor operates by shininga beam of light out through the lens. When an object comes within the sensor’s view, it reflects part of this beam of light back to the sensor causing the sensor to detect the object. The maximum range at which a given object can be detected depends on how well its surface reflects light—the less light it reflects back, the shorter the range. The ability of a surface to reflect light depends primarily upon its material of construc-tion, color, and texture.This manual covers both forward viewing and right angle viewing models. Although the units differ in the location of the lenses, the basic fundamentals of installation, set-up, and operation are nearlyidentical.ForwardviewingMountingMounting location and set-upThe Prism sensor features a threaded housing and includes jam nuts and washers. This allows mounting into any 0.75 inch hole, or optional bracket. Use caution to avoid cross-threading the jam nuts on the sensor body. Tighten nuts to less than 4 N•m (36 in.-lbs. or 3 ft.-lbs.) torque to avoid stripping threads.A second mounting method is to use #4 hardware in the 0.125 inch diameter mounting holes in the flat sides of the sensor. This is ideal for mounting the Prism against a wall, piece of equipment, rail, mounting bracket, etc.Select a mounting location with a clear view of the object to be detected. Avoid direct reflection from a highly reflective background (or darken the background). Mount the sensor so that it points at the most suitable part of the target object.Be sure your power supply is off, then connect the sensor to thecontrol circuit and power lines. Turn the power supply on and place a sample object in the beam. Slowly turn the gain adjustment clockwise (see Warning above concerning pot adjustment) until the LED lights (for light-operate model). Note the position and remove the sample object. Now continue turning the gain setting clockwise to find the position where the LED lights from the background reflec-tion.

The device is available in an adjustable version and fixed output voltages, such as 1.2V, 1.5V, 1.8V, etc. Supply current with no load is 300uA and drops to <1uA in shutdown. The 2.5V to 6.5V input voltage range makes the APS2415 ideally suited for single Li-Ion, two to four AA battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM pulse skipping mode operation provides very low output ripple voltage for noise sensitive applications. Switching frequency is internally set at 1.2MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.6V feedback reference voltage.

It utilizes internal MOSFETs to achieve high efficiency and can generate very low output voltage by using internal reference at 0.6V. It operates at a fixed switching frequency, and uses the slope compensated current mode architecture. This Step-Down DC-DC Converter supplies 1500mA output current at Vout = 1.8V with input voltage range from 2.5V to 6.5V.Chipownconverter decreases. Caution must be exercised to ensure the heat dissipated not to exceed the maximum junction temperature of the IC. Note 5: The duty cycle D of a step-down converter is defined as:D = TON × f OSC × 100% ≈V OUT × 100% VINWhere TON is the main switch on time and fOSC is the oscillator frequency (1.2MHz).Current Mode PWM ControlSlope compensated current mode PWM control provides stable switching and cycle-by-cycle current limit for excellent load and line responses and protection of the internal main switch (P-Ch MOSFET) and synchronous rectifier (N-CH MOSFET). During normal operation, the internal P-Ch MOSFET is turned on for a certain time to ramp the inductor current at each risingedge of the internal oscillator, and switched off when the peak inductor current is above the error voltage. The current comparator, ICOMP, limits the peak inductor current. When the main switch is off, the synchronous rectifier will be turned on immediately and stay on until either the inductor current starts to reverse, as indicated by the current reversal comparator, IZERO, or the beginning of the next clock cycle. The OVDET comparator controls output transient overshoots by turning the main switch off and keeping it off until the fault is no longer present.Maximum Load CurrentThe APS2415 will operate with input supply voltage as low as 2.5V, however, the maximum load current decreases at lower input due to large IR drop on the main switch and synchronous rectifier. The slope compensation signal reduces the peak inductor current as a function of the duty cycle to prevent sub-harmonic oscillations at duty cycles greater than 50%. Conversely the current limit increases as the duty cycle decreases.Layout GuidanceWhen laying out the PCB board, the following suggestions should be taken to ensure proper operation of the APS2415. These items are also illustrated graphically in Figure 4 & Figure 5. 1. The power traces, including the GND trace, the SW trace and the VIN trace should be kept short, direct and wide. The VFB pin should be connected directly to the feedback resistor. The resistive divider R1/R2 must be connected between the (+) plate of Cout and ground. Connect the (+) plate ofC1 to the VIN pin as closely as possible. This capacitor provides the AC current to internal power MOSFET. Keep the switching node, SW, away from the sensitive VFB node. Keep the (-) plates of C1 and C3 as close as possible.Idle Mode OperationAt very light loads, the APS2415 automatically enters pulse skipping Mode. In the pulse skipping Mode, the inductor current may reach zero or reverse on each pulse. The PWM control loop will automatically skip pulses to maintain output regulation. The bottom MOSFET is turned off by the current reversal comparator, IZERO, and the switch voltage will ring. This is discontinuous mode operation, and is normal behavior for the switching regulator.2.3.4. 5.Dropout OperationWhen the input voltage decreases toward the value of the output voltage, the APS2415 allows the main switch to remain on for more than one switching cycle and increases the duty cycle (Note 5) until it reaches 100%. The output voltage then is the input voltage minus the voltage drop across the main switch and the inductor. At low input supply voltage, the RDS(ON) of the P-Channel MOSFET increases, and the efficiency of the8/F, ChuangYuan BuildingNo.21-1 Changjiang Road, Wuxi New Destrict Tel: +86(510)8521-7718/doc/0b17328324.htmlV0.05/8APS2415ChipownFigure4.

The external resistor sets the output voltage according to the following equation:R2 VOUT = 0.6V × 1 + R1R1=200K? for all outputs; R2= 200k? for VOUT=1.2V, R2=300k? for VOUT =1.5V, R2=400k? for VOUT =1.8V, andR2=633.3k? for VOUT =2.5V.Sumida CDRH5D16 Sumida CDRH8D28 Coiltronics SD532.23.34.7 2.0 3.3 4.73.0 2.6 3.4 3.3 2.6 2.128.7 35.6 19 23 29 395.8x5.8 x1.8 8.3x8.3 x3.0 5.2x5.2 x3.0Inductor SelectionFor most designs, the APS2415 operates with inductors of 1µH to 4.7µH. Low inductance values are physically smaller but require faster switching, which results in some efficiency loss. The inductor value can be derived from the following equation: Input Capacitor SelectionThe input capacitor reduces the surge current drawn from the input and switching noise from the device. The input capacitor impedance at the switching frequency shall be less than input source impedance to prevent high frequency switching current passing to the input. A low ESR input capacitor sized for maximum RMS current must be used. Ceramic capacitors with X5Ror X7R dielectrics are highly recommended because of their low ESR and small temperature coefficients. A 22µF ceramic capacitor for most applications is sufficient.L=VOUT × (VIN ? VOUT ) VIN × ΔI L × f OSCWhere ΔI L is inductor Ripple Current. Large value inductors lower ripple current and small value inductors result in high ripple currents. Choose inductor ripple current approximately 35% of the maximum load current 1500mA, or ΔI L =525mA. For output voltages above 2.0V, when light-load efficiency is important, the minimum recommended inductor is 2.2µH. For optimum voltage-positioning load transients, choose an inductor with DC series resistance in the 50m? to 150m? range. For higher efficiency at heavy loads (above 500mA), or minimal load regulation (but some transient overshoot), the resistance should be kept below 100m?. The DC current rating of the inductor should be at least equal to the maximum load current plus half the ripple current toOutput Capacitor SelectionThe output capacitor is required to keep the output voltage ripple small and to ensure regulation loop stability. The output capacitor must have low impedance at the switching frequency. Ceramic capacitors with X5R or X7R dielectrics are recommended due to their low ESR and high ripple current. The output ripple VOUT is determined by:ΔVOUT ≤VOUT × (V IN VOUT ) 1 × ESR + V IN × f OSC × L 8 × f osc × C 38/F, ChuangYuan BuildingNo.21-1 Changjiang Road, Wuxi New Destrict Tel: +86(510)8521-7718/doc/0b17328324.htmlV0.06/8APS2415Package InformationChipown8/F, ChuangYuan BuildingNo.21-1 Changjiang Road, Wuxi New Destrict Tel: +86(510)8521-7718/doc/0b17328324.htmlV0.07/8APS2415ChipownImportant NoticeChipown Microelectronics Co.

General Description
The APS2415 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version and fixed output voltages, such as 1.2V, 1.5V, 1.8V, etc. Supply current with no load is 300uA and drops to <1uA in shutdown. The 2.5V to 6.5V input voltage range makes the APS2415 ideally suited for single Li-Ion, two to four AA battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM pulse skipping mode operation provides very low output ripple voltage for noise sensitive applications. Switching frequency is internally set at 1.2MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.6V feedback reference voltage. The APS2415 is available in a small SOT package.
