Astral Calorimeters, 8mm to 25mm
Scientech offers a large selection of calorimeters that support a wide range of wavelengths and power. Astral Series calorimeters from Scientech store all calibration data with the detector. The 8 and 25mm aperture models are grouped together because they all support 10W power levels. For measuring low power or energy (<30 mW or 30 mJ), Scientech recommends application of our Isoperibol™ enclosure (Model 360203A) to minimize environmental thermal interference. The 16 and 50mm aperture models are grouped together because they all support 30W power levels. Astral Series detectors are available in either surface or volume absorbing models with apertures of custom sizes or standard aperture models. 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. These calorimeters require an Astral Power Meter.
