Volume-absorbing thermopile sensor for measuring pulsed & CW lasers between 100 mW and 30W.

Key Features:

·      100 mW to 30W range

·      19 mm diameter active area

·      Volume absorbing sensor

·      0.25 to 3 µm spectral range

·      Convective air-cooled

·      ISO 17025 accredited

This PM30V1 laser power sensor is designed for use with high peak power, low repetition rate, Q-switched Nd:YAG lasers up to 30W. A volume absorbing substrate mounted in front of the detector absorbs to bulk of the laser energy, instead of hitting the detector element directly. The results in a much higher damage resistance, approaching 2 J/cm2, at relatively low repetition rates of approximately 10 pps.

 A removable front aperture allows easy replacement of the volume-absorbing substrate should it be damaged. Replacement absorbers may be ordered using part number 0011-8935.

The sensor is terminated in a SmartSensor DB25 cable and is directly compatible with all power meters in the catalog.
