PowerMax-Pro 15 mm OEM Detectors High-Speed, Compact Power Detector with Large Active Area for Integration Inside Laser Systems 15 mm PowerMax-Pro OEM detectors are intended for integration inside laser systems with narrow process windows. The high-speed and high-power handling of these detectors offers advantages over semiconductor photodiodes and other infrared detectors commonly used in feedback loops and inline QC monitoring applications. Small infrared detectors and photodiodes only sample a portion of the beam leading to errors and instability, they have steep spectral response curves, and require significant attenuation to avoid saturation. PowerMax-Pro OEM detectors will resolve these types of design challenges. PowerMax-Pro thin-film transverse thermoelectric power sensing technology (Patent #9,012,848) offers the broad wavelength sensitivity, large dynamic range of a thermopile with a fast ten microsecond response speed. 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
  • Compact form factor for OEM integration

APPLICATIONS

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

See PMP 15mm Development Kit Sensor user manual for integration guidelines. 2 Coherent recommends using these detectors in current mode with a transimpedance amplifier. See PMP 15 mm Development Kit Sensor user manual for integration guidelines. 3 The “UP” type detectors are recommended only for small beams <2 mm diameter in fixed installations with minimal beam movement. For larger beams choose HD or BB models. PowerMax-Pro 15 mm OEM Detector Optical Reflectivity PowerMax-Pro 15 mm OEM Detector Optical Absorptivity
