Two key trade fairs for the optics and photonics industry – SPIE.Photonics West and SPIE.AR|VR|MR – are scheduled to take place at the San Francisco Moscone Center from 22-27 January 2022.

Novel display technologies, such as near-eye and microLED displays, enable exciting new user experiences. However, they also impose big challenges for quality control, especially with substantial production tolerances and spectral variances of light sources.

Next generation OLEDs displays have in principle endless contrast ratios due to their emittive nature and their ability to completely turn off pixels. This makes them ideal in applications that require low display luminance like use in dark/nighttime conditions.

Instrument Systems has developed a practicable concept for the laser safety assessment of VCSELs based on the international laser safety standard. With absolutely calibrated and modular test systems, such as the pulsed VCSEL tester PVT 100/110 and camera-based VTC 2400, the complete characterization of pulsed VCSEL arrays is possible. Since VCSEL arrays are experiencing a drastic growth in 3D sensor applications, e.g. face ID, automotive LiDAR and human-machine-interfaces (AR/VR), proof of eye safety is becoming increasingly important.
