The usual dot measurement with 660nm red dot laser alignment should have to work for quite long time and still maintaining good laser beam stability. It should be made with good metal heat sink cooling system and import 660nm red laser diode as its beam emitting source. In continuous dot measuring work, it always gets increasing laser beam stability of at least 40% and extremely stable red dot projection for both long distance and long time. It is generating highly visible red laser light from beam aperture, however, it should also avoid operation under sunlight, otherwise, high power red laser would generate highly clear red reference dot under high lighting effectively.
Within wide range output power of 5mW to 100mW, 660nm red dot laser alignment is projecting high quality red laser light at various work distances. However, under condition that it gets serious need of highly clear and accurate dot measurement, it is just getting the recommended work distance of no more than 25 meters. Otherwise, red laser beam might become large, which is not any longer applicable for quite compact size red reference dot generation at longer distance.
In various industrial and high tech dot measuring work fields, 660nm red dot laser alignment should have to work with super strong environmental stabilization. The adoption of durable aircraft used aluminum alloy housing tube is bearing wide range operating temperature, but also should have to work with highly stable dot alignment under various working environments. Red Laser light is quite sensitive to real working condition. However, within wide range operating temperature of -10 degree to 45 degree Celsius, 660nm red laser module is still generating highly visible and bright red laser light, without any laser light decay or dim in constant use.
Besides the use of formal industrial dot measuring works, 660nm red dot laser alignment is mainly used for those of high tech work fields. It gets wide range applications of DNA sequencing, FLIM, Raman imaging and laser light excitation etc. Whatever kind of working surface it is pointing, this alignment laser just allows quite easy adjustment of laser beam focus and dot generating direction within three dimensions. Every time it gets correct choice of output power and installation, it allows no track, no barrier and no mistake dot alignment.
