The Astral Series detectors are available in either surface or volume absorbing models with apertures of
custom sizes or standard 8mm, 16mm, 25mm, 50mm, 100mm, and 200mm aperture models. The surface
absorbing models are ideal for measuring continuous wave lasers while the volume absorbing models
are well suited for pulsed lasers using either the watts mode or single pulse energy mode.
