We have added the AFC-500 chart collimator for MTF and resolution testing to our lineup. "By using a collimator lens, it is possible to measure resolution at infinity. The light source can be optionally selected from halogen, LED, cold cathode tubes, and more.

Automatically measures lens spherical aberration using the Shack-Hartmann method, compatible with lenses ranging from 20 to 500mm. Image processing with high-resolution CMOS.
