What is the best solution to make highly clear and accurate dot alignment at great distance? It is not easy to get ideal dot alignment with a simple red laser pointer or manual dot projecting tool, but it would be very nice substitute to make use of a 635nm 50mW red laser diode module (http://www.berlinlasers.com/635nm-red-laser-diode-module). It projects low divergence and high purity red laser light directly from 635nm red laser diode. When it gets less than 1mrad laser beam and good cooling system, this industrial stabilized red dot laser makes sure of the most compact size red dot projection continuously.
The special use of glass coated lens and glass window in front of laser beam aperture assure high transmittance red laser beam emission, and highly stable performance under dust or moisture. Owing to its strict laser beam stability tests up to 24 hours and proper adjustment of laser beam focus, high power 635nm red dot laser achieves the most concentrated red laser light and the most precise dot indication at great distance and high lighting perfectly.
