Pyro-electric detector L series

thermalsingle-channel

Pyroelectric detectors are thermal detectors; i.e. they create an electric signal due to temperature changes in the chip. This temperature change is caused by absorption of light. We do use LiTaO3 and DLaTGS as pyroelectric materials. Basically such detectors cover the whole spectra. However, they are mainly used for mid-wave and long-wave infrared detection (MWIR and LWIR). In addition, the usage in the THz region seems to become more popular these days. Single Channel Current Mode Pyroelectric Detector One-Channel LiTaO3 Pyroelectric Detector Pyroelectric LiTaO3 single-channel detectors are available for current mode (CM) and voltage mode (VM) Single-channel IR Detector This product line uses LiTaO3 as the chip material. We offer a broad range of active sizes and packages. Our smallest package is a TO-46 and our largest standard chip size is 3.0 x 3.0 mm2. We also offer versions for all common methods of driving pyroelectric detectors. These detectors can be tailored to applications by integrating bandpass filters or broadband windows. For details please see the separate “Filter and Window Selection Sheet”. Two different types of pyroelectric detectors are available: Current mode CM detectors L11 & L21 series Voltage mode VM detectors L31 & L41 series
