The 919P-250-35 Fan Cooled Thermopile Sensor is a general purpose thermal sensor measuring optical power up to 250 W. It's spectrally flat coating covers the wavelength range 0.19 - 11 μm. It has an active diameter of 35 mm and can measure continuous optical power from 150 mW to 250 W and single shot energy from 50 mJ to 300 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-250-35风扇冷却热电堆传感器是一种通用热传感器,测量光功率可达250w。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35mm,可以测量从150mw到250w的连续光功率和从50mj到300j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。
