High power IR emitter, as a key component in the field of infrared technology, has been widely used in various applications such as remote control, night vision, and thermal imaging. This article will introduce the industry of high power IR emitter, including its definition, working principle, application fields, market status, and future development trends.

Definition and Classification of High Power IR Emitter

High power IR emitter refers to an infrared radiation source with high radiant power. It can be divided into two types according to the emission principle: thermal emitter and semiconductor laser emitter. Thermal emitter uses the heat energy of the filament to emit infrared radiation, while semiconductor laser emitter uses the optical amplification effect of the semiconductor material to emit infrared radiation.

Working Principle of High Power IR Emitter

The working principle of high power IR emitter is based on the physical law of thermal radiation and the optical amplification effect of semiconductor materials. The thermal emitter converts electrical energy into heat energy through the filament, and then emits infrared radiation through thermal radiation. The semiconductor laser emitter converts electrical energy into optical energy through the optical amplification effect of the semiconductor material, and then emits infrared radiation through optical radiation.
