Astral 200mm aperture surface absorbing disc calorimeter designed for large diameter or diverging beams. Measures up to 150W power or 300J energy. Broadband, 250 nm-35µm, flat spectral response from UV to mid IR. Ideal for measuring continuous wave lasers. Used extensively in scientific research, measuring single pulse energy levels up to 1.5 kJ, they have also been used for measuring laser range finders, LiDAR systems, and measuring laser diode arrays or metal vapor lasers. Stand not included; may be ordered separately.
