If there is quite long time spending for user to make manual line drawing or printing works, however, nothing can be helpful at all to obtain ideal line aligning accuracy under night vision illuminated work fields. Under constant work on the most practically used laser device under night vision, it should be quite great technical innovation to develop 200mW 980nm infrared line laser module. When it is projecting invisible infrared laser beam and infrared laser line from beam aperture, only if it is equipped with night vision device of CCD camera, black and white camera or infrared laser camera, this IR laser line generator is workable with extremely clear and accurate IR line alignment in distance.
When line alignment work is proceed for quite long time, not simply used for temporary positioning work as a quite simple IR laser pointer, the design with 200mW 980nm infrared line laser module would have to be made with super strong industrial stabilization. According to basic use of inner metal heat sink cooling system and copper made IR laser diode core part inside the durable metal housing tube, this IR laser alignment achieves excellent thermal emitting and highly stable IR reference line projection in continuous use.
In process of constant IR line alignment work, 200mW 980nm infrared line laser module gets the best use of qualified glass coated lens or separate crystal lens. It is keeping work with quite high photoelectric ability, and then generating even more powerful and intense IR laser beam while comparing with formal visible laser devices. When the front part of laser line generator gets special use of glass window in front of laser beam aperture, the genuine IR laser line alignment is not affected at all, but keeping highly reliable IR line projection under any moisture or dust working condition etc.
Under the most important design part of adjustable focus, 200mW 980nm infrared line laser module makes quite easy IR laser beam concentration, and extremely fine and clear IR reference line projection in distance easily. Human eyes cannot observe any type of IR laser radiation and reflection. However, it is still a key issue to pay high attention to IR laser hazards, and remember to wear 980nm wavelength preventing IR laser safety goggles so as to achieve highly secured and free IR line alignment perfectly.
