This document describes the Electronic-Library Service provided by ICminer.com, which was created in 2003. It provides a detailed description of the features and characteristics of this service.
This document provides technical specifications for PbSe (Lead Selenide) photoconductive detectors manufactured by Hamamatsu. These devices are capable of detecting wavelengths up to approximately 5 micrometers and operate on the same principle as PbS cells but with higher response speed. They are suitable for applications such as gas analyzers and precision photometry.
| Lower Temperature Detection Limit | Approx. 50 C |
|---|---|
| Operating Temperature | -30 to 450 C |
| Storage Temperature | -55 to +60 C |
| Maximum Supply Voltage | 60 V |
| Chopping Frequency | 600 Hz |
The spectral response ranges from 1.5 to 5.8 um.
The noise increases exponentially, which degrades the S/N ratio.
