DSC-E3MR
Lens MTF Tester
DSC-E3MR is one of the extended modules of the DSC-E3 system, which is integrated with the infinity and 10 cm object distance optical system and high precision rotation stage.
The high precision rotation stage is for MTF analysis of a lens in different azimuths, which can be switched to a tray for mass production as usual.
Both single analysis and mass production modes can cooperate with 2 object distances optical systems that can be exchanged automatically.


APPLICATION
Mobile phones, NB, security, AR, VR, TOF, fingerprint, endoscope, and other types of lens.

FEATURES

 Automatic object distances switching system between infinity and 10cm for measurement is available.
 UMA Patent:DSC-E3MR 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.
 The high precision rotation stage for MTF analysis of a lens in different azimuths is an optional upgrade.
 For a user to be able to choose the most suitable focus-scanning mode freely, both free run and trigger run are available.
