Description

The Gentec-EO QE series is a robust line of high performance and high accuracy pyroelectric joulemeters that are designed to measure laser energy. Each modular unit is built for durability, compactness and ease of operation. 

The QE optical absorber exhibits high damage thresholds and can operate at high rep-rates. The QE series can be used to even higher energy levels with QED attenuator / diffuser.
