Not any longer relying on any visible laser devices or other manual dot projecting tool, in order to make the most satisfied dot alignment under night vision work fields, it is just a quite nice chance to make use of advanced IR laser diode tech. It is never an end to develop the most advanced and practically used IR laser device, such as a 980nm infrared laser diode module. It is projecting invisible infrared laser beam and IR laser dot from beam aperture. Under proper equipment with night vision device, it is producing highly intense IR laser light and highly clear IR reference dot projection in distance efficiently.
When dot alignment is processed under night vision work fields, 980nm infrared laser diode module would also be used under quite special work fields of military targeting, laser medical therapy, surveillance and intelligence system etc. It is not limited for quite close distance IR dot projection work, but also have to work for quite long work distance. When it is employing 980nm infrared laser diode within 100mW to 500mW, it is producing highly intense IR laser beam and highly clear IR reference dot as long as 100 to 1000 meters in use.
Under condition that there is quite accurate IR dot projection in distance, 980nm infrared laser diode module should be made with qualified optic lens. Under operation of qualified glass coated lens and quite special design with front part glass window, this IR dot laser is always workable with quite high laser beam transmittance and extremely clear IR reference dot projection without any light decay or blur in continuous work. Under quite easy screw of laser beam aperture, this dot laser alignment tool ensures easy adjustment of laser beam focus and the clearest IR reference dot projection in distance effectively.
Once 980nm IR laser diode is processed into a practically used dot alignment tool of 980nm infrared laser diode module, it is always required to make continuous dot projection and excellent laser light cycling use. The most important design part of APC, ACC driving circuit board is preventing any electric current impacting and serious increasing temperature, applied for the most stable IR dot projection under long distance and long serving lifetime. Any eye exposure to IR laser radiation and reflection might cause serious hurt to human eyes, under proper wearing of infrared laser safety goggles, this infrared dot laser achieves highly secured and accurate dot measurement constantly.
