What is an Infrared Laser Diode Module?

An infrared laser diode module is a device that consists of an infrared laser diode, a driver circuit, and an optical system. The laser diode is the core component that emits infrared light, which is then focused and directed through the optical system. The driver circuit provides the necessary electrical power to the laser diode and ensures stable operation. Infrared light has a wavelength range of 700 to 3000 nanometers, which falls between visible light and microwave radiation. It is invisible to the human eye but can be detected by specialized sensors and cameras. Infrared laser diode modules are widely used due to their compact size, low power consumption, and high efficiency.
