820nm multi mode infrared laser diode module applies a wavelength of 820nm, belongs to a near infrared regain laser device, which gets good penetration ability infrared laser light source emission. Owing to its small scattering and absorption ability of propagating in the atmosphere, it can be transmitted over a long distance.

In practical infrared laser light emission work, it adopts an AC/DC adapter as its electric power source. Supported by 5V, 9V or 12V operating voltage DC power supply, under appropriate driving conditions, only a small current is required, this 808nm multi mode infrared lase diode can emit infrared laser light source immediately, with the lowest power consumption. When it is made into an infrared laser diode module, it also gets ultra compact size tube and light weight. In addition, this accessory part is always allowing easy integration into various miniaturized devices and systems, providing greater flexibility for design and application. It can make fast response to changes in electrical singles, realize fast optical signal emission and modulation, thus meets the needs of applications such as high speed data transmission and fast control.

In process of long time lasting infrared laser light source emission, 820nm infrared laser diode module has a long serving lifetime and stable performance, which can work continuously under different environmental conditions. The unique use of an APC, ACC driving circuit board assures constant output power and electric current supply, cooperating with inner metal heat sink cooling system design, this 820nm IR laser is able to make long time lasting infrared laser light source emission as long as 8 to 10 hours per day.

Advantages: The infrared laser light source emission by the 820nm infrared laser diode module is invisible, which will not cause any irritation and interference to the human eyes, and gets good confidentiality. It is not easily disturbed by visible laser light and can work stably under various lighting conditions. It makes good compatibility with other optical components and detectors, which is convenient for system integration.
