Definition of Infrared Light Source

An infrared light source refers to a device that emits infrared radiation. Infrared radiation is a type of electromagnetic wave with a wavelength longer than visible light. It is widely used in various fields due to its unique properties, such as heat radiation, thermal imaging, and non-destructive testing.

Types of Infrared Light Sources

1. Solid-state infrared light sources Solid-state infrared light sources mainly include LED infrared light sources and laser infrared light sources. LED infrared light sources have the advantages of low cost, high stability, and long service life. Laser infrared light sources have high brightness, narrow beam width, and good focusing ability. 2. Gas discharge infrared light sources Gas discharge infrared light sources include carbon arc lamps, mercury lamps, and halogen lamps. These lamps have high luminous efficiency and can produce a wide range of infrared wavelengths. 3. Quantum infrared light sources Quantum infrared light sources use quantum cascade lasers and other quantum effects to generate infrared radiation. They have the advantages of high brightness, narrow linewidth, and high efficiency.
