If dot measuring work is processing for those of night version illumination fields, not workable at all to only rely on simple manual dot projecting tool or a laser pointer, it would become a much better solution to apply a long wavelength of 980nm made device, such as an infrared laser diode module. It applies an import infrared laser diode and a qualified glass coated lens inside a durable metal housing tube, together with constant electric power source supply and different operating voltage electric power source, this direct diode emission made infrared dot laser alignment always enables easy reaching, long lasting and high precision infrared reference dot projection for all night version dot positioning works.

The adoption of a 980nm infrared laser diode module applies a long wavelength of 980nm, which emits invisible infrared laser beam and infrared reference dot from beam aperture, thus human eyes cannot observe them at all. It is suitable for requiring concealed operations (e.g., security indication and military-assisted positioning), avoiding interference from visible light. Comparing with short wavelength infrared or ultraviolet lasers, it has a higher threshold for thermal damage to human skin and eyes, making them safer in medical and consumer electronics applications. Basically 980nm infrared dot laser alignment applies an import IR laser diode within 5mW to 500mW and high power up to 600mW to 1000mW, after its basic use of a metal heat sink cooling system inside different dimension metal housing tube, it enables superior nice heat dissipation and ultra stable infrared dot projection in continuous use.

Inside the high duration anodized aluminum alloy housing tube, 980nm infrared laser diode module applies a qualified glass coated lens and adjustable focus optic lens. Every time it gets constant electric power source from an AC/DC adapter, it keeps work with highly powerful and high penetration infrared laser light source emission at several miles far away. Under those of moisture, dust, rain, water or fog etc, it still maintains ultra clear and stable infrared dot projection. In addition, when highly powerful and intense infrared laser beam is focused from beam aperture, this infrared dot laser alignment enables efficient conversion of increasing accuracy and brightness infrared dot alignment at longer distance. Owing to its low energy consumption and high electro-optical conversion efficiency, it can still make clear and accurate IR dot indication in long term use. It can penetrate mist and smoke better than visible light and short-wavelength infrared, providing enhanced stability in harsh industrial environments (such as dusty workshops) or low-light conditions outdoors.

Applications in night version illumination fields:

Biomedical: Used in laser therapy (e.g., relieving muscle pain, promoting wound healing), laser acupuncture, and biological tissue imaging (e.g., aided by confocal microscopy).

Industrial Inspection: 980nm infrared laser diode module is used as a precision alignment light source (e.g., for circuit board soldering positioning, mechanical part assembly calibration), and laser ranging (for medium- and short-range, high-precision ranging equipment).

Security Monitoring: Integrated into infrared night vision systems for target indication, marking surveillance area boundaries, or used in conjunction with infrared cameras for covert lighting.

Consumer Electronics: 980nm infrared alignment laser can be used for 3D sensing (e.g., facial recognition-assisted positioning in some mobile phones), signal transmission for laser mice/remote controls, and as light source components for micro-projection devices.
