DSC-E3WE
Lens MTF Tester
DSC-E3WE Series is a kind of system designed for applying MTF test to lens inspection.
High speed, high precision, reproducibility good, reasonable price, etc., and is compatible with the industry standard.
APPLICATION
Mobile phones, NB, security, AR, VR, TOF, fingerprint, endoscope, and other types of lens.
FEATURES
✔ A single system can support amazingly large FOV 6˚ ~190˚ measurement.
✔ UMA Patent：DSC-E3WE supports various kinds of reticle patterns, such as Cross Line, on Distortion compensation and MTF measurement without additional reticle and optical information.
As a result, the calibration process and reticle cost can be significantly deducted.
✔ With an advanced optical system, DSC-E3WE supports measurement at infinity and finite object distance. Furthermore, the shortest object distance can reach 20cm.
✔ Replacing brackets is not needed when switches lens types between regular and Wide-Angle lenses.
✔ For a user to be able to choose the most suitable focus-scanning mode freely, both free run and trigger run are available.
Optional Upgrade
✔ Optional upgrade of Micro Distance Measurement Subsystem is available, which is suitable for fingerprint recognition, medical and certain cellphone applications.
✔ Upgrading the system for 5x Zoom Lens test is available.
