In various precise and fine line measurement for those of night version fields, it is not easy to reach with any visible laser device or manual line drawing device, but substituting by Berlinlasers 980n infrared line laser alignment. It emits intense and powerful infrared laser light. Cooperating with 5V, 9V 1000mA DC power supply, it enables freely installed distance of 3 meters, easy and quick reaching of infrared line onto any raw material surface.
This 980nm infrared line laser module applies qualified glass coated lens or separate crystal lens. It should be working without light decay or blur. After strict laser beam stability test and aging preventing test up to 24 hours, and proper use by skilled users, it is working well with highly stable and no decay light IR line emission in long lasting use. According to its freely adjusted infrared line fineness and line emitting direction, it brings users the lowest price and the most reliable IR line measurement for military targeting, infrared laser sight and communication, surveillance and high tech work etc.
