Description:
The FL250A-BB-35 is a general purpose fan cooled thermal power/energy laser measurement sensor with a 35mm aperture. It can measure power from 150mW to 250W and energy from 50mJ to 300J. It has the spectrally flat broadband coating and covers the spectral range from 0.19 to 20µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.

Notes: (a) Calibrated at specified wavelengths only: 532nm, 755nm, 1064nm and 2940nm
Notes: (b) Above 1.1µm there is an additional calibration uncertainty of up to 2%
Notes: (c) For lower powers up to 30W it is recommended to work with the fan off and then the noise level is ~5 times lower. It is also recommended to measure energy with the fan off
Notes: (d) When sensor is hot, there can be large zero offset up to 300mW
