DPE12 Pyroelectric Infrared Detector
A room-temperature infrared detector assembly with an internal preamplifier and voltage output. Modulated illumination and synchronous detection support scanning infrared measurements.
Best suited to
Mid- and long-wave infrared spectroscopy without cryogenic cooling.
Selecting a configuration
Use a modulated signal and select the acquisition time constant with the modulation frequency. Provide the desired wavelength interval when choosing windows and the complete optical path.
