实验室金相显微镜使用及操作规程Usage and Operating Instruction of Laboratory Metallographic Microscope

1、检查供电电压在显微镜适用范围内后电源与显微镜相连接。

After checking the power supply voltage in the range of metallographic

microscope application, making the power connect to metallographic

microscope.

2、旋转电位器旋钮，使其处于亮度最低位置，打开显微镜电源开

关，然后调节电位器使亮度适中。

Spin the button of potentiometer to reach to the minimum brightness point, and open the power switch of metallographic microscope, then adjust the potentiometer to reach to actual brightness.

3、安放试样先确认先前所选载物片合适后再将要观察的试样放

置在载物片上，注意将被观察面向下，用弹簧压片将试样固定好，旋转载物台手轮将试样移入光路。

The Sample Imposition, Firstly confirming the microscope slide is suitable or not, and then put the sample which need observed onto microscope slide, the observation section must be down, fixing the sample by spring pressed, spinning the hand wheel of object stage and making the sample into light path.

4、转动物镜转换器将低倍物镜置入光路，慢慢转动粗动手轮，

用左眼从左固定筒目镜观察，见物像大致轮廓后用微调手轮将物像调清晰，然后将高倍物镜置入光路。

Spin the Nosepiece, Making the low-power objective into light path, spinning coarse motion hand wheel slowly, observing from the left eyepiece by left eye, when observing blear outline, adjusting by fine-adjustment hand wheel to image brilliant, then making the high-power objective into light path.

5、双目曈距调整及视度调节曈距调整：双手分别握住双目左右

支架转动，直至双目中看到的光环完全重合，此时曈距即已调好。视度调节：双目观察调焦时，应先以固定筒一侧观察，即右眼从右侧观察，物像调清晰后再从左筒观察，同时调节左筒上的视度调节圈以补偿左右两眼视度上的差异，使两筒成像同样清晰。

Pupil Distance Adjustment and Diopterregulation, Pupil Distance Adjustment: Two hands hold the left and right sides bracket of binocular and revolve until then the ring observed by two eyes reclosing completely, at this time; the

pupil distance is adjusted well. Diopterregulation: When binocular

observation focusing, should observe from fixed lens barrel firstly, that is

observing from right side by right eye, when image is brilliant, observing from the left side and adjusting oxyopter adjusting ring on left eyepiece to

compensate oxyopter difference of two eyes and make two cylinder imaging the same clear.

6、视场光栏调节搏动视场光栏拨杆或转动视场光栏转圈，将

视场光栏调至小于目镜的视场，此时视场中可看见完整的视场光栏像。调整视场光栏中心调解螺钉，使视场像中心与目镜视场中心基本重合。再将视场光栏像开至略小于目镜视场再次调节，使光栏中心与视场中心更加吻合后，调大视场光栏，使视场光栏像消失于目镜视场范围之外即可。

Field Stop Adjustment throbbing field stop deflector rod or revolving field stop torgimbi, adjust field stop less than eyepiece viewing field, at this time, observing the whole field stop image from viewing field. Adjust the core adjustment screw of field stop to make the center of field image is coincidence basically with the center of eyepiece viewing field. Then adjust the viewing field larger than before but also slightly less than eyepiece viewing field and make center of diaphragm is more coincidence with the center of viewing field, adjust the field stop larger and make field stop image disappear out of the range of eyepiece viewing field.
