Key features

Very Low Noise Levels

Noise levels of a photo detector, but with the high energies of a pyroelectric:

  • 50 nJ with the MT coating
  • 100 nJ with the BL coating

2 coatings Available:

  • BL: black coatings, sensitivity of 900 V/J, readings up to 400 Hz
  • MT: metallic coating, sensitivity of 2400 V/J, readings up to 1000 Hz
