DSC-E3UW
Lens MTF Tester
DSC-E3UW is a specially designed MTF tester for a wide-angle lens inspection.
For the Ultra-Wide view angle test requirement, the new dome design supports up to 195˚ FOV without bracket changing needed. By providing high precision, repeatability with a reasonable cost inspection solution, and compatibility with the industry standard, DSC-E3UW is the first choice in R&D evaluation and incoming quality control.
APPLICATION
Highly suitable for automotive, sport, and surveillance applications.
FEATURES
✔ A single system can support amazingly large FOV 14˚ ~195˚ measurement.
✔ Replacing brackets is not needed when switches lens types between regular and Wide-Angle lenses.
✔ 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-E3UW supports measurement at infinity and finite object distance.
Furthermore, the shortest object distance can reach 20cm.
✔ For a user to be able to choose the most suitable focus-scanning mode freely, both free run and trigger run are available.
✔ A single tray can place 10 pieces of M12 lenses, and the time for the tray in and out is around 1.5 seconds.
Optiona Upgarde
✔ Upgrading the system for 5x Zoom Lens test is available.
