Frequently Asked Questions

A Gentec-EO calorimeter is a reliable solution for measuring the largest and highest energy laser beams. It is manufactured, calibrated, and serviced by Gentec-EO, which has become an expert in this field through cooperation with leading research facilities around the world.

The Custom Calorimeter 351nm 400mm Rectangular Aperture has outstanding signal to noise ratios, high sensitivity, vacuum compatibility, and attention to detail and workmanship. It also uses NIST traceable sources and proven calibration techniques to ensure accuracy.

The calorimeter can measure beams as large as 420 x 427 mm in aperture size, and can withstand pulse energy densities of more than 15 J/cm2.

The calorimeter can measure energy in the range from 190 nm to 25 microns.

The calibration uncertainty of the calorimeter is ±3%, and repeatabilities are better than ±2% for very large beams.
