Technical details and manufacturing context for Optical Source/IR Emitter

Definition
An optical source or infrared emitter is a critical component within a concentration sensor that produces infrared light at specific wavelengths. This emitted light interacts with the substance being measured, and the resulting absorption or scattering is detected to determine concentration levels. It serves as the active illumination element in optical concentration measurement systems.
Working Principle
The emitter generates infrared radiation, typically through electroluminescence in semiconductor materials like LEDs or laser diodes. When electrical current passes through the device, it excites electrons that release energy as photons in the infrared spectrum. This controlled emission provides the light source that passes through or reflects off the sample material.
Common Materials
Gallium Arsenide (GaAs), Indium Gallium Arsenide (InGaAs), Silicon Carbide (SiC)
