The Sunglasses are placed in a tool that simulates a Headform according to ISO 18526-4:2018 Type 1-M Standard. While watching the real-time video streaming coming from the internal camera, the operator can control the alignment and visually check the gradient pattern orientation.
It is possible to examine relative differences in position and inclination between the filters. No mechanical setup is required. The New software Easy_Tester_Pro provides the offset of the points measurement matrices “Big Head” and “Small Head”.

Its intuitive touch screen user-interface makes Easy_Tester_Pro easy-to-use even for unskilled workers. The machine is perfect for massive production quality inspection, close to the line control and incoming review.

This Uniformity Tester provides accurate and repeatable measurements and outputs a simple « Pass / Fail » lamp showing a complete result screen view. The results can be print or export in excel and pdf files.
