Astral 100mm Aperture Calorimeters
Scientech's 100 mm aperture, volume absorbing and surface absorbing calorimeters measure average power up to 50W. Calibration data is stored in detector.
The surface absorbing models are ideal for measuring CW lasers while the volume absorbing models are designed for pulsed lasers using either the watts mode or single pulse energy mode.
This calorimeter requires use of an Astral Power Meter.
