Pyroelectric detectors application advice:

  • DPe22 pyroelectric detectors can respond over a wide range of wavelengths, and the actual working wavelength range is limited by the window materials. Based on actual needs you can choose the suitable window material.
  • DPe22 pyroelectric detectors can be used with lock-in amplifiers. SR830 or Model 420 is recommended.
  • DPe22 pyroelectric response rate is in inverse proportion to the modulation frequency, which is suitable for lower frequency (under 70Hz)
