A laser power meter consists of a laser power sensor (or called detector head) , display unit and relevant accessories. Our sensors can measure the laser beams at the laser wavelengths from 190nm to 25um and maximum laser power of 5000W. These power meters are used in the laser power measurement and monitoring.
Detectable Spectral Range : 0.19 to 25μm
The sensors and monitors are sensitive and thus can be used to monitor laser power inside lasers and laser machines for on-time monitoring. Also can be used in compact & portable laser power meters.

All above sensors can be used as sensors to measure laser power, also can be used as beam dumps. However, if you just need a beam dump and not measure laser power, please just buy the beam dump at lower prices. The part number of the beam dump is ended with BD at the corresponding sensor. For example, the sensor is STCH-W5000-CA-55 and the corresponding beam dump is STCH-W5000-CA-55-BD.
A complete laser power meter may be a sensor + a display unit, or a sensor + a USB output (the USB output can be connected to PC). All the display unit can be connected to PC.
All the accessories such as sensor supports are optional.
We can custom-design and -make the sensors and powermeters according to your specific requirements and please contact us for more discussions.
