In order to get precise and fine enough line alignment at different work distances, without the use of sunlight and high lighting , it makes easy job with an intense beam emitting tool of 445nm blue laser line generator. It is projecting formal brightness blue laser light directly from an inner 445nm blue laser diode. The durable structure anodized aluminum alloy housing tube is configuring with metal heat sink cooling system and APC, ACC driving circuit board, it achieves excellent thermal emitting and up to 85% stability blue line alignment in long time use. This blue laser line generator allows freely selected fan angles of 10 to 110 degree glass coated lens. It is passing through up to 24 hours aging preventing test and aging preventing tests, and allowing proper use by skilled users or professionals. It should be selecting with correct output power and glass coated lens. When it makes proper adjustment of blue line fineness and line projecting direction within three dimensions, this blue laser assures no track and no mistake use constantly. Technical data: Item: Berlinlasers 445nm blue laser line generators Output power: 50mW, 80mW, 100mW Optic lens: 10-110 degree glass coated lens Line lengths: 0.5 meter to 6 meters Applications: laser show, laser displaying, military targeting, and lab experiment etc https://www.berlinlasers.com/445nm-glass-lens-blue-laser-line-genrerator
