Basic Concepts of Infrared Laser Diode Module

An infrared laser diode module is a compact, high-efficiency, and stable light source that uses an infrared laser diode as the core. It is composed of an infrared laser diode, a lens, a heat sink, and a driver circuit. The infrared laser diode emits infrared light through the lens, and the driver circuit controls the output power and stability of the laser diode. Infrared light has a wavelength range of 700nm to 1mm, which is invisible to the human eye. It has the characteristics of strong directional, high monochromaticity, and high brightness. Therefore, infrared laser diode modules have been widely used in various fields.

Types of Infrared Laser Diode Modules

According to the different wavelengths, infrared laser diode modules can be divided into three types: near-infrared, mid-infrared, and far-infrared. 1.
