The 919P-050-26 General Purpose Thermopile Sensor measures laser power up to 50 W. Intermittently, it can handle up to 150 watts for 1.5 minutes or 100 watts for 2.2 minutes. It's spectrally flat coating covers the wavelength range 0.19 - 11 μm. It has an active diameter of 26 mm and can measure power from 40 mW to 50 W and single shot energy from 20 mJ to 30 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-050-26通用热电堆传感器可测量高达50w的激光功率。间歇性地,它可以处理150瓦1.5分钟或100瓦2.2分钟。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,可以测量功率从40mw到50w,单发能量从20mj到30j。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。
