Laser Measurement Instruments

PM10K+ Laser Power Sensor

Increase measurement speed of high-power lasers up to 5X with this unique sensor, which goes to 10 kW continuous/12 kW intermittent on beams up to 65 mm diameter.

Novel technology enables the PM10K+ to deliver power measurements of high-power lasers in under 3 seconds - faster than ever before. Compatible with lasers from the UV through the IR, it also offers convenience features for mounting and alignment.

High-Power Sensor Options

Choose models compatible with Coherent meters or directly ready for system integration. All feature the same large area detector and fast response speed.
