Lens MTF Tester

• Support FOV 179˚ (diagonal) measurement to achieve wide-angle inspection requirements.

• MTF Test and Distortion correction chart are both designed in a one reticle that simplified calibration process and much cost-effective.

• Combination of 9~25 image regions provides customers to purchase upgrades and expansion easily.

• Enhanced structural design allows machine operating in general factory environment without any additional vibration isolator.

• Program controlled motorized collimator can meet different objective distances measurement requirements.
