Precise Aligned 445nm Blue Laser Line Generator for Security and Monitoring Field Whenever highly bright beam is emitted from an import 445nm blue laser diode, cooperated with a qualified glass coated lens within 10 to 110 degree fan angle, it gets great creation of a professional line measuring tool of a 445nm blue laser line generator. It keeps work with moderate blue light penetration, controllable light curtain coverage and sensitive response. Owing to ultra compact structure design, it allows easy easy concealed installation, and quick reaching of blue line onto any vertical or horizontal surface immediately. After correct use of output power and optic lens fan angle, and properly adjusted blue line thickness, this laser line generator makes good job for perimeter security alarm system, forming an invisible protective light curtain by emitting a single line. When the light curtain is blocked, an alarm is triggered, suitable for perimeter protection of factories, warehouses, villas, etc. After its properly adjusted blue line thickness and line emitting direction, it brings users noncontact, no mistake and low cost line indication for all security and monitoring fields conveniently. https://www.berlinlasers.com/445nm-glass-lens-blue-laser-line-genrerator
