The 919P-600-65 Fan Cooled Thermopile Sensor is an improved version of 919P-500-65, pushing the maximum power level up to 600 W. It's spectrally flat coating covers the wavelength range 0.19 - 11 µm. It has a large active diameter of 65 mm and can measure continuous optical power from 500 mW to 500 W and single shot energy from 100 mJ to 600 J. It has a 1/4-20 tapped hole for post or plate mounting and comes with a 1/2 inch diameter post. Calibration of the thermopile detector is required annually to assure NIST traceability.  Comes with a power supply to turn the fan.

919P-600-65风扇冷却热电堆传感器是919P-500-65的改进版本,最大功率达到600w。这是幽灵似地平涂层覆盖了波长范围0.19 - 11µm。它具有65毫米的大有源直径,可测量500 mW - 500 W的连续光功率,100 mJ - 600 j的单发能量。它有1/4-20的柱或板安装抽头孔,有1/2英寸直径的柱。每年都需要校准热堆探测器,以确保NIST的可追溯性。带有驱动风扇的电源。
