eFLAT-II - Flexible Light Analyser and Test System

eFLAT-II: Flexible Light Analyzer and Test System

More reliable and faster testing of light emitting diodes with accuracies from laboratory measurements that can be transferred to production.

The eFLAT systems are designed for very fast, parallel and automatic testing of both color and intensity of LEDs, displays, dashboard lights and other self-luminous objects. The color testing system covers the entire spectrum of visible light from dark to the brightest LEDs and provides highly exact color analysis and intensity detection with outstanding repeat accuracy and ease of operation. The network interface makes this system ready for Industry 4.0.
