One-Channel LiTaO₃ Pyroelectric Detector

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”.

Current Mode Detector - CM

Currently, the op-amp-based current mode (CM) is only used by a minority of users; however, this minority is rapidly growing. We strongly recommend using this method of driving, especially for new developments. In our experience, customers profit from the following advantages: There is a relatively large signal on top of a small offset. In addition, this offset is more consistent across a wider temperature range.

This series has the following designation: L11 for detectors without temperature fluctuation compensation (TFC) and L21 for those with TFC. In general, L21 series components have a higher performance ratio than those of the L11 series.
