• Ø50mm aperture
Description:
The L1500W-LP2-50 is a water cooled thermal power/energy laser measurement sensor for high power density and long pulse lasers. It has a 50mm aperture and can measure power from 15W to 1500W and energy from 500mJ to 200J. Its high damage threshold LP2 coating covers the spectral range 0.35 – 2.2µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.
New: QBH-Fiber Adapters (see 'Accessories' below): for mounting fiber with QBH termination to this sensor.

Notes: (a)
Calibrated for ~0.8µm, 1.064µm and 10.6µm
For spectral range 0.35 to 1.1µm
Notes: (b)
Water temperature range 18-30°C. Water temperature rate of change <1°C/min. Pressure drop across sensor 0.03MPa.
The recommended flow rate can be lowered proportionately at lower than full power but should not be below the minimum.
When used at full power with substantially below the recommended flow rate, the damage threshold may be as much as 20% lower. The response time will be optimum with the recommended flow rate.
