Models are available with either silicon or InGaAs diodes.
The detectors are ideal for viewing low light level sources, such as the rapid modulation of laser diodes or LED's or for triggering applications. Models are available with either silicon or InGaAs diodes. The ET2020UV is a general purpose detector with an enhanced ultra-violet response. It comes with its own 48V power supply. Applications include viewing the output of excimer lasers, nitrogen lasers and the fourth harmonic of solid state lasers.
