Lead Sulfide Crystal Substrate can be used to measure radiation. Stanford Advanced Materials (SAM) offers a variety size of PbS Single-crystal Substrate. We have a professional sales team to offer a fast response within 24 hours and warm service.
As an infrared detector, Lead Sulfide Crystal Substrate functions as a photon detector, responding directly to the photons of radiation, as opposed to thermal detectors, which respond to a change in detector element temperature caused by the radiation.

Lead Sulfide Crystal Substrate can be used to measure radiation in either of two ways: by measuring the tiny photocurrent the photons cause when they hit the PbS material, or by measuring the change in the material’s electrical resistance that the photons cause. Measuring the resistance change is the more commonly used method.
