ImageMaster® PRO VR – Measurement Solution for Testing VR Lenses and VR Modules in Production
The TRIOPTICS ImageMaster® product group is a comprehensive system of measurement devices for determining the imaging quality of optical assemblies. The ImageMaster® PRO VR was specifically developed for the measurement of VR lenses and VR module qualification in production environment. The system measures the MTF, EFL, chromatic abberation and distortion as well as the veiling glare index which is an important figure of merit of VR lenses.
Key Features:
- High end MTF test system for production
- 1.5 s measurement time per sample (depending on sample), UPH 2340
- Up to 27 cameras
- Automatic handling of samples using automated tray system
- Simulation of human eye
- Aperture to simulate the special near to eye display requirements
- Measurement possible for various pupil distances and sizes
- Off-axis angle continuously adjustable from full FOV 20° to 170°
- Motorized telescope (+/- 2 dioptres) (on request)
- Eyebox Scanning (on request)
- Measurement possible for various wavelengths (RGB)
- Integration of customer display possible (on request)
- High intensity light source
- Suitable for clean room class ISO 5

Software MTF PRO
The recognized ImageMaster® PRO software, called MTF-PRO, has been further improved. It features increased speed, advanced performance and clearly displayed test results. The optimized MTF algorithms are the result of the continuous improvement and TRIOPTICS years of experience in the field of MTF measurement.
Enhanced MTF-Pro Software
Advantages
- Automatic pass or fail results based on a multitude of freely selectable criteria
- Software enabling real-time images of all cameras.
- Individual setting of spatial frequencies for each camera
- Settings to enable focusing curve for on-axis and/or off-axis cameras
- Three security levels: setup files and critical functions are password protected
