Sensor Developer’s Kits High-Speed and Large-Area Power Detector for Integration Inside Laser Systems PowerMax-Pro thin-film transverse thermoelectric power sensing technology (Patent #9,012,848) offers the broad wavelength sensitivity and large dynamic range of a thermopile with the fast response speed of small infrared detectors. The microsecond response time enables nearly instant power measurement without any overshoot, and can pro - vide pulse energy, peak power, and rise/fall time with modulated sources. These detectors are designed for integration into laser systems for real-time QC monitoring and in-line control. PowerMax-Pro sensors alleviate issues common to semiconductor and infrared detectors that have smaller active areas and steeper spectral response curves. FEATURES & BENEFITS

  • High-speed 10 microsecond response time
  • High-power handling to 9 W
  • Supports lasers from 400 nm to 11 microns
  • Broadband coating available with flat spectral response
  • Large 15 mm square active area

APPLICATIONS

  • Laser power monitoring of CW or modulated laser systems
  • Active feedback control within laser processing systems
