Remarks:

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.
