Large-Area High-Power Water-Cooled Thermopile Sensors to 5 kW Designed to Measure Large Laser Diode Stacks and Arrays, and other High-Power Divergent Sources Water-cooling and careful thermal management within these sensors enable them to deliver kW level power handling capacity. They can capably measure industrial diode laser sources and bar arrays at power levels from 100 W up to 5 kW. The PM1K-100, PM3K-100 and PM5K-100 provide a range of power capabilities in a 100 mm diameter size, and are also useful for diode bars and large cross-section laser beams. The PM5K-200 features a 200 mm diameter detector, and is specifically intended to measure the power output of large laser diode bar arrays. FEATURES & BENEFITS

  • Maximum power from 1 kW to 5 kW
  • Minimum power down to 100 W
  • Water-cooled
  • 0.15 µm to 11 µm spectral range
  • 100 mm and 200 mm active area diameters
  • RoHS compliant
