The 919P-150-26 Fan Cooled Thermopile Sensor is a general purpose thermal sensor measuring optical power up to 150 W. It's spectrally flat coating covers the wavelength range 0.19 - 11 μm. It has an active diameter of 26 mm and can measure continuous optical power from 50 mW to 150 W and single shot energy from 20 mJ to 100 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.



919P-150-26风扇冷却热电堆传感器是一种通用热传感器,可测量高达150w的光功率。这是幽灵似地平涂层覆盖了波长范围0.19 - 11μm。它的有效直径为26毫米,可以测量从50mw到150w的连续光功率和从20mj到100j的单发能量。它有一个1/4-20的螺孔用于柱或板安装,有一个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。
