Gentec-EO Energy Detectors

Gentec-EO's pyroelectric energy meters cover a very wide range, going from nanojoules to several tens of joules per pulse. They also come in various sizes, from 8 mm to 95 mm in diameter and most of them are available with an optional attenuator.

For a list of all available models, please read further below.
