When users are trying to make highly precise dot measurement for all night version illumination fields, it makes good job with a long wavelength made Berlinlasers 980nm infrared dot laser alignment within 100mW to 500mW. The adoption of an import IR laser diode and metal heat sink are configured with different dimension metal housing tube. It just enables easy installation, good thermal emitting and highly stable IR dot projection in long lasting use.
This 980nm infrared laser diode module applies an AC/DC adapter, not spending extra time on battery change, this 980nm infrared laser diode module is working well with constant infrared laser beam emission, highly clear and stable IR dot projection within long lasting time of 8 to 10 hours. Only after its proper mounting onto night version device, within freely installed distance of 3 meters, it assures no barrier and no mistake dot measurement for IR laser sight, night hunting, surveillance, intelligence system, optical instrument and high tech etc.
