Whenever highly precise and clear dot indication is in serious need for those of optical experiment works, under operation of special night version illumination fields, a lot of engineers and professionals would prefer to operate a long wavelength made device of a 980nm infrared laser diode module. The 980nm near infrared band is compatible with most infrared detection and receiving equipment commonly used in optical experiments, resulting in a wide range of experimental applications. Being made with an import IR laser diode and a qualified optic lens inside a durable metal housing tube, cooperated with an external electric power source, this direct diode emission made 980nm infrared dot laser alignment assures highly stable and clear infrared reference dot generation for multiple optical experiment fields conveniently.

Being made with an AC/DC adapter, not spending extra time on prior battery change, 980nm infrared laser diode module always makes constant electric power source supply. Supported by an import 980nm infrared laser diode within 5mW to 500mW and 600mW to 1000mW output power, configured with a metal heat sink cooling system inside a different dimension metal housing tube, it enables excellent infrared laser beam quality, and highly focused infrared reference dot projection. When infrared dot laser alignment gets small beam divergence angle, cooperated with adjustable focus optic lens, after its concentrated infrared laser light emission, it is converted into an increasing accuracy and brightness infrared dot at different work distances, meeting the core requirements of optical experiments for the shape and consistency of the light source beam.

Whenever 980nm infrared laser diode module projects invisible and intense infrared laser beam from different output power made IR laser diode, it is completely invisible to the naked eyes, which does not produce visible light glare that interferes with experimental observations. When it is used with infrared imaging equipment, the infrared laser beam path can be clearly captured, facilitating experimental data recording and analysis. Being made with APC, ACC driving circuit board, whatever output power it is selected, infrared dot laser alignment ensures long term lasted infrared reference dot indication for all optical experiments, with no barrier to operation. owing to its low power consumption and low energy projection, it has a negligible impact on the experimental environment temperature. It does not require complex auxiliary cooling equipment, simplifying maintenance and reducing experimental setup costs.
