Laser 2000

OEM Sensor AHW Series

There are 7 different products in the AHW series, all varying with different power modes, coatings and aperture diameters. Please find all the variations and their specifications below, or contact us to find out more about our products.

Laser 2000 OEM laser sensor Disks and laser heads are based on high sensitivity thermopiles. They have resistant materials and coatings that extend their applicability from UV to Far Infrared and to concentrated beams, without damaging even at extreme power densities.

These thermopiles also exhibit a high degree of linearity over their entire working range and have large areas to sample the whole laser beam.

  • Slim design for installation in tight areas
  • Flexibility in integration: various connection types, models with / without ampl circuits; cased/non-cased solutions
  • Coatings with high power densities for any application
  • Usable with Customers’ own electronics or software
  • NIST & PTB traceable calibration procedures

Custom sensors, housings and electronics can be designed to fit your requirements – please ask for details.
