Laser power sensor 3A series

thermopile

3A is a very sensitive thermopile based laser power/energy sensor with very low noise and drift. It has a 9.5mm aperture. It can measure from 10µW to 3W and from 20µJ to 2J. It is spectrally flat and covers the spectral range from 0.19 to 20 µm. The sensor comes with a 1.5 meter cable for connecting to a meter or PC interface.
