ImageMaster^® PRO AR – Testing of waveguides on wafers

ImageMaster^® VR/AR

Measurement Systems for Virtual and Augmented Reality Optics

The ImageMaster^® product group offers a wide variety of measuring instruments for determining the optical performance of lenses and optical systems. With the ImageMaster^® AR/VR series, TRIOPTICS offers highly accurate and fast test systems for the qualification of virtual and augmented reality optics in research and development as well as for mass production. The test systems measure single components like waveguides, lenses and projectors as well as complete VR/AR modules.

Unique

The ImageMaster^® VR/AR is world´s unique instrument for the complete qualification of VR and AR optics.

Extensive measuring parameters

As usual with the ImageMaster^® series, many other parameters relevant for the determination of image quality are measured in addition to the MTF.

Reliability

Measuring instruments you can rely on are our claim. When it comes to measuring accuracy you can count on the traceability of our measurement data to international standards.
