• Fan cooled
• Up to 500W
• Ø50mm aperture
Description:
The FL400A-BB-50 is a general purpose fan cooled thermal power/energy laser measurement sensor with a 50mm aperture. It can measure power from 300mW to 400W continuously and to 500W intermittently. It can measure energy from 75mJ to 600J. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.

Notes: (a) 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: (b) This LP2 sensor is calibrated for 0.35-1.1µm and 10.6µm. For other wavelengths in the spectral range 1100 – 2200nm there is an additional calibration uncertainty of up to 1%.
