Data Sheet

The measurement of laser power is quick and simple with our power meter. The hand held power meter is a low cost light weight alternative to bulky two-piece thermopile power meters and probes.

STY Series Hand-held CO2 Laser Power Meter

The hand-held laser power meter STY-HLP-200B is a CO2 laser power meter. Its measurement range is maximum 200W with the resolution 0.1W. A button battery is used as the power supply and thus it is very easy and portable used in production, QC and laboratory. A mount hole is alternatively used to be fixed instead of hand-held for better stability.

STCH Series Lasers Power Meters

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.

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.
