Infrared 850nm lamps have become increasingly popular in various industries due to their unique properties and applications. This article aims to provide an in-depth introduction to the infrared 850nm lamp industry, covering its history, technology, applications, and future prospects.

History of Infrared 850nm Lamps

The concept of infrared radiation has been known for centuries, but it was not until the late 19th century that scientists began to study the properties of infrared light. In the early 20th century, infrared lamps were developed for various applications, such as heating and medical treatments. The development of infrared 850nm lamps, however, can be traced back to the 1960s when they were first used in telecommunications.

Technology of Infrared 850nm Lamps

Infrared 850nm lamps are devices that emit infrared radiation at a specific wavelength of 850nm. This wavelength is in the near-infrared region of the electromagnetic spectrum, which is invisible to the human eye. The technology behind these lamps involves the use of semiconductors, specifically gallium arsenide (GaAs) and indium gallium arsenide (InGaAs) materials, which are capable of emitting infrared radiation at 850nm. The process of producing an infrared 850nm lamp begins with the growth of a GaAs or InGaAs semiconductor wafer. The wafer is then patterned with a series of structures that serve as the optical cavity, which determines the wavelength of the emitted light. The wafer is then diced into individual chips, which are mounted onto a substrate and coated with an anti-reflection layer to enhance the output power.

Applications of Infrared 850nm Lamps

Infrared 850nm lamps have a wide range of applications across various industries. Some of the most common applications include: 1. Telecommunications: Infrared 850nm lamps are used in optical communication systems for transmitting data over fiber optic cables. The 850nm wavelength is preferred due to its low attenuation in fiber optic cables, which allows for longer transmission distances. 2. Medical Diagnostics: Infrared 850nm lamps are used in various medical diagnostic devices, such as endoscopes and optical coherence tomography (OCT) systems. The near-infrared wavelength allows for deeper tissue penetration and higher resolution imaging compared to visible light. 3. Industrial Automation: Infrared 850nm lamps are used in industrial automation systems for sensing and imaging applications. They can be used to detect the presence or absence of objects, measure distances, and inspect products for defects. 4. Security and Surveillance: Infrared 850nm lamps are used in security and surveillance systems for night vision and thermal imaging applications. The near-infrared wavelength allows for the detection of heat signatures, which can be useful for identifying individuals or objects in low-light conditions. 5. Consumer Electronics: Infrared 850nm lamps are used in consumer electronics devices, such as remote controls and gaming consoles, for wireless communication with other devices.
