World Leading Manufacturer - Lead Salt Infrared Detectors

24 May 2018

LASER COMPONENTS is a world leading manufacturer of lead salt infrared detectors. We

supply customers all over the world with these industrial grade thermal detectors, from our

research and production facility in Arizona.

These detectors work on the principle that photons incident on the polycrystalline thin film,

promote electrons across the bandgap increasing the conductivity of the material, in turn

decreasing the resistance of the substance. The polycrystalline lead sulphide (PbS) units

detect radiation in the wavelength range between 1 and 3.3 microns and exhibit a higher

sensitivity than polycrystalline lead selenide (PbSe) which can detect radiation between 1

and 5.2 microns.

The devices are manufactured in standard TO style packages and have long expected

lifetimes making them ideal for fit and forget applications such as gas sensing, surface

inspection and flame detection. The PB25 device is a collection of uncooled polycrystalline

biased single element PbS detectors that operate at room temperature with a 20% cut off at

3.0 microns and a maximum element size of 6 x 6 mm².
