DSC-E3DV
Lens MTF Tester
The characteristic of this system is capable of change the subject distance from 20cm to infinity and virtual image continually via software control.
High speed, high precision, reproducibility good, reasonable price, etc., and is compatible with the industry standard.
APPLICATION
It is suitable for large quantity mass production in variety of applications such as mobile phones, NB, security, AR, VR and other types of lens.
FEATURES
✔ UMA multinational patent：With the capability of changing object distances controlled by software, DSC-E3DV can fulfill the measurement requirements at different object distances, including virtual images, such as VR/AR.
✔ UMA patent：DSC-E3DV 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 automatic integration test function of day and night modes is available.
✔ With an advanced optical system, DSC-E3DV supports measurement at infinity and finite object distance. Furthermore, the shortest object distance can reach 20cm.
✔ The supported FOV range covers 20˚ ~ 190˚, which can fulfill most of lens test requirements.
✔ For a user to be able to choose the most suitable focus-scanning mode freely, both free run and trigger run are available.
