Coherent PowerMax-Pro Sensors

The newest generation in sensor technology enhances productivity


PowerMax-Pro (Patent Pending) represents a dramatic technological advancement in laser power sensing that combines the broad wavelength sensitivity, dynamic range and laser damage resistance of a thermopile with the response speed of a semiconductor photodiode.

Coherent has developed a new high-speed, thin film sensor technology for laser power measurement. Its unique transverse thermal flow design enables fast, high power measurmeent, with high damage resistance. The sensor is so fast, less than ten microseconds in the case of the "HD" version, that users can trace the pulse shape of modulated lasers at pulse repetition frequencies up to 25kHz.


  • Measures power in 10's of microseconds
  • High power up to 150W for HD models and 200W for BB models
  • Supports lasers from UV to Far-IR wavelengths
  • Capable of tracing the individual pulse shape of modulated and long pulse lasers
  • Large 30 x 30mm active area
