In special need of clear dot measurement under night vision, it is a very nice experience to use a long wavelength made 980nm 100mW infrared dot laser alignment. It is projecting invisible infrared laser beam and IR laser dot from beam aperture. When it is operating as an accessory part, equipping with night vision device and connects with DC input power supply, 980nm infrared laser module achieves high photoelectric ability IR laser light emission and highly clear IR dot generation in distance. This 980nm 100mW infrared dot laser alignment employs import 980nm infrared laser diode as beam emitting source. In continuous IR dot generation, owing to special use of metal heat sink cooling system and APC, ACC driving circuit board, this durable structure infrared laser module achieves superior nice thermal emitting and constant IR dot generation in long time use. Only if it gets proper installation and adjustment of laser beam focus, it achieves no mistake and no barrier IR dot measurement perfectly.
