eFLAT-HG-II - Flexible Light Analyser and Test System

eFLAT-HG-II: Flexible Light Analyzer and Test System

For testing light sources with high-resolution PWM.

Premosys has created the eFLAT-HG-II for testing high-resolution PWM modules as well as extremely weak illumination LEDs. The Ethernet interface enables fast communication and allows the system to be integrated directly into a network. User configurable combinations of sensitivity and integration time enable very short cycle times.
