Features

Interference-resistant open design that is easy for any operator to use

Interference resistant: Built on MiCRO-LiGHT’s operator-friendly design, measurements are unaffected by ambient light and the system minimizes angle-related issues when testing polarized lenses.
Simple operation: The open measurement area and streamlined interface enable quick place-and-measure testing.
Automatic evaluation: The system completes the measurement, displays the data, and provides a PASS / FAIL result automatically, allowing non-specialist operators to work quickly and accurately.
