Description:
The 15K-W-BB-45 is a water cooled thermal power/energy laser measurement sensor for very high powers with a 45mm aperture. It can measure power from 100W to 15,000W. It has a deflecting cone and annular absorber that withstands high power densities to 10kW/cm². It covers the spectral range from 0.8 - 2 and 10.6µm. The sensor comes with a standard 5 meter cable for connecting to a meter or PC interface.

Notes: (a)
Calibrated at 1.07μm and 10.6μm.
For other wavelengths in the range 0.8 – 2μm, the calibration error may be up to ±2% more.
Notes: (b)
When scatter shield is installed, use the NIRS setting to compensate for slightly higher reading.
When not installed, use the NIR setting.
Notes: (c)
For circular beam centered within ¼ of beam diameter. IMPROPERLY CENTERED BEAM CAN
CAUSE DAMAGE TO SENSOR.
Maximum tilt angle ±5 degrees. For rectangular beam please consult Ophir representative.
Notes: (d)
Water temperature range 18-30ºC. Water temperature rate of change <1ºC/min. The recommended
flow rate can be lowered proportionately at lower than full power but should not be below 3 liter/min.
The response time will be optimum at near 12 liter/min flow rate.
