I3.3 - Recent Developments in Photoconductive Infrared Arrays

Brian Elias
The infrared region from 1µm to 5µ is an area of interest for both spectroscopic and thermographic applications. Lead sulphide (PbS) and lead selenide (PbSe) are intrinsically photoconductive materials that cover this important spectral region and have a long history of development and manufacturing. They have several advantages over competing materials, but because of their nature, they have several challenges that need to be addressed. This paper will outline the application of several established technologies...
