UMA / PRODUCTS / Lens MTF Tester
DSC-E1MR

1

DSC-E1MR is integrated 10 cm with high precision rotation stage in current DSC-E1 architecture. Lens clocking control and switching between infinity and 10 cm objective distance measurement can be easily controlled in software.
It is suitable for mobile phones、NB、 monitoring and other small lens mass line production testing. High speed, high precision, reproducibility good, reasonable price, etc., and is compatible with the industry standard.

Features
  • 10cm and Infinity mechanism measurement are combined in one machine to provide higher test efficiency and more cost-effective.
  • With accurate rotation stage, pairing can be achieved fast.
  • MTF Test and Distortion correction chart are both designed into one reticle that provide higher test accuracy and more cost-effective.
  • Combination of 9~25 image regions provides customers to purchase upgrades and expansion easily.
  • Enhanced structural design allows the machine can be being used in general factory environment without any additional vibration isolator.
