High Power Water Cooled Thermal Sensors
20W to 5000W
Features
• Powers up to 5000W
• Water cooled
• Ø50mm aperture
• 5000WP for non-contaminating water flow
Description:
The 5000W-BB-50 is a water cooled thermal power/energy laser measurement sensor with a 50mm aperture. It can measure power from 20W to 5000W. 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.
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 0.06MPa. 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.
Notes: (c)
The 5000WP-LP2-50 has nylon rear housing and nothing but nylon and copper in contact with the water flow. This prevents contamination of the water flow with aluminum and prevents the possibility of corrosion.
