When 50mW blue cross laser alignment makes excellent use of an import 445nm blue laser diode, it is always getting at least 40% improvement of laser beam stability in continuous use. It is projecting less brightness blue laser light than 473nm blue DPSS laser. However, it gets direct blue laser light emission directly from 445nm blue laser diode, which is only adopting quite small size 16mm diameter aluminum alloy housing tube. Any time it leaves enough space for inner metal heat sink cooling system, this cross line laser module just achieves superior nice thermal stabilization and highly stable blue vertical and horizontal lines generation within 8 to 10 hours per day.
Designing with high quality glass coated lens, no appearance of laser light decay or dim in continuous use, 50mW blue cross laser alignment is always projecting high linear quality cross line source at great distance. It is different from a simple blue laser pointer, which should have to work with good beam stability in long time use. Any time this 445nm blue laser module passes through quite strict laser beam stability tests and aging preventing tests up to 24 hours, under operation by skilled users or professionals, it is maintaining good laser beam stability and highly clear blue cross line projection in continuous use.
Whatever kind of working surface it is pointing, under basic measurement and experiment of cross line length, fineness and work distance, 50mW blue cross laser alignment enables correct selection of fan angle, thus projecting the most precise blue cross line source at great distance and other formal lighting working occasions. At the same time, after quite easy screw of adjustable focus optic lens, this alignment laser enables immediate blue laser light focusing and the most precise cross line projection in distance. In addition, any time users are paying high attention to potential danger of thermal energy hurt and wearing correct laser safety goggles, it achieves highly secured and highly precise cross line projection constantly.
