DSC501S system is developed for DSC lens; the optical design is Orthographic Projection. It is using single lens load/unload by manually method which is suitable development, making pair and import inspection.
Measurement principle is based on ISO12233 and using digitalized image process to provide promptly, accuracy and reliable MTF (SFR) test for optical inspection.

Features:

• The maximum test points are 97 points which are the same effect as 49 CCDs in back projector system that provide a relatively cheap and complete test solution.
• Test Chart costs low and has high flexibility.
• Color Sensor provides chromatic aberration test.
