Astral 200mm Aperture Calorimeter
Scientech's 200 mm aperture, volume and surface absorbing calorimeters are made for use with average laser power up to 150W or diverging beam lasers. Calibration data is stored in the detector.
These calorimeters support CW or pulsed lasers, some models with peak pulse power densities up to 45 GW/cm2.
This calorimeter also requires use of an Astral Power Meter.
