The DET-L-PYK5-R-P detector for LIDA™ houses a lithium tantalate pyroelectric detector with an integrated FET amplifier and signal processing circuitry. Typical pyroelectric detectors have an output which decreases with increasing chopping frequency. The signal processing circuitry following the low noise FET amplifier integrated into the sealed detector can housing compensates for this effect and produces a uniform output signal over chopper frequencies ranging from 8-1100 Hz. The DET-L-PYK5-R-P»s KRS5 window allows for sensitivity from 0.6-50 &mu,m. The unique, flat shape of this detector»s spectral response curve only requires the detector to be calibrated at a single wavelength, 633 nm. This 2 mm diameter active area pyroelectric detector has its sensitivity adjusted to 1000 V/W over this sensitivity region.
