• Size of the sensor? – That defines the required image circle of the lens: e.g. a 2/3 inch format CCD requires a lens with image circle 11 mm diagonal e.g. a 8k 7µm line scan CCD requires a a lens with image circle 58 mm
processing applications.
Our Mission: Providing high quality optical solutions for image processing applications helps system integrators and
equipment manufacturers to enhance their vision systems. Our engineering and product developments are driven by the requirements derived from long-term partnerships with our customers. Our employeຫໍສະໝຸດ Baidus are the fundamental success factor and we trust in their commitment to solve our customer’s problems. Our 90-years of expertise in optical design and manufacturing allows us to produce superior products and provide a professional consultancy and support to contribute to the success of our customers.
• Lens interface? – That defines the mechanical adaptation and for some interfaces the distance between flange and sensor: e.g. C-mount (flange – sensor distance 17.52 mm) e.g. F-mount (flange – sensor distance 46.5 mm) for other interface such as M42 or M72, you need to know the camera specific distance
• Pixel size? – That defines the required image side resolution of the lens: e.g. a 7 µm pixel size means a Nyquist frequency of 72 lp/mm e.g. a 5 µm pixel size means a Nyquist frequency of 100 lp/mm
