When users are looking for a low production cost and easy operating dot measuring tool, not relying on a simple red laser pointer or manual dot projecting tool, it is making even better job with Berlinlasers 685nm 5mW to 100mW red laser diode module. It is projecting formal brightness red laser light directly from a 685nm red laser diode. It gets featured advantages of low production cost, easy operation, quick response and no mistake dot alignment. Designed with 16mm and 26mm diameter anodized aluminum alloy housing tube and extending electric wires, 685nm red laser diode module enables freely installed distance of 3 meters, and quick red dot projection onto any raw material surface. It generates noncontact and no track red dot aligning source from beam aperture. After correct use of output power and proper mounting onto industrial device, this red laser makes sure of no mistake and no barrier use in all occasions perfectly. Applications: drilling system, laser marking machine, laser engraving machine, lab experiment and high tech https://www.berlinlasers.com/685nm-5mw-10mw-20mw-30mw-50mw-80mw-100mw-red-laser-diode-modules
