  • Rugged LiTaO3 material
  • 610°C Curie temperature
  • 0.2%/°C temperature stability
  • Non-hygroscopic
  • Broad spectral range: .001 to 1000 microns
  • Low noise
  • 0°C to 70°C operation
  • Optional windows
  • Low-leakage current hybrid FET preamplifiers
  • Low NEP: 0.3 x 10-9 W/(Hz0.5)

The P1-70 series features 1, 2, 3, and 5 mm diameter standard detector element sizes (respectively, P1-71, P1-72, P1-73, and P1-75) and incorporates a specially selected low-leakage current hybrid FET circuit. Because it uses a (3*1011) -ohm load/feedback resistor, this series offers superlative narrow-band, low-NEP performance.
