Introduction to Infrared 850nm Lamp

The infrared 850nm lamp, as the name suggests, emits light at a wavelength of 850 nanometers in the infrared spectrum. This specific wavelength falls within the near-infrared region, which is invisible to the human eye. The infrared 850nm lamp is widely used in various applications due to its distinct advantages over other infrared lamps.

History and Evolution

The concept of infrared radiation has been known for centuries, but it was not until the late 19th century that scientists began to study and utilize infrared light in practical applications. The development of infrared 850nm lamps can be traced back to the early 20th century when they were first used in military applications for night vision devices. Over the years, significant advancements have been made in the technology of infrared 850nm lamps. Early models were bulky and inefficient, but with the advent of solid-state lighting, the industry witnessed a transformation. Modern infrared 850nm lamps are compact, energy-efficient, and offer superior performance.

Principles of Operation

The operation of an infrared 850nm lamp is based on the principles of solid-state lighting. These lamps typically consist of a semiconductor material, such as gallium arsenide (GaAs), that emits light when an electrical current passes through it. The semiconductor material is doped with impurities to create a p-n junction, which generates photons when electrons recombine with holes. The 850nm wavelength is achieved by selecting the appropriate semiconductor material and doping concentration. The emitted light is then directed through a lens or fiber optic cable to the desired application. The efficiency of the lamp is determined by the quality of the semiconductor material and the design of the optical system.
