In a lot of precise device manufacturing work fields, in order to make precise and quick enough cross line projection onto various working surfaces, it is always making an easy job after the use of a 50mW pro red cross laser alignment. It is generating the purest red laser light from 635nm red laser diode. It just projects at least 3 times brighter red laser light than formal 650nm red laser with the same output power. On condition that 635nm red laser module gets proper use of optic lens degree and proper mounting onto other machine or device, it is able to work with the most complex two perpendicular lines with accurate 90 degrees.
The usual cross line measurement with 50mW pro red cross laser alignment is always processing for quite long time, and still maintaining highly stable cross line projection. Different from a very simple manual or mechanical cross line measuring tool, only if it gets constant power source from DC power supply, it is just making continuous red laser beam emission, and red cross line source emission from beam aperture at quite long work distance. Accepting wide range electric current of 100V to 240V, after correct converting into 9V 1000mA electric power source, it just assures constant and highly bright red vertical and horizontal lines generation with accurate 90 degrees.
According to the use of qualified glass coated lens with different fan angles of 10, 15 and 110 degree, 50mW pro red cross laser alignment is projecting the most complex two perpendicular lines with accurate 90 degrees, and also generating different dimension cross line lengths within 0.5 meter to 6 meters. For the most important of all, when it passes through up to 24 hours aging preventing and beam stability tests, after its proper use by skilled users or professionals, this cross line laser module achieves good laser light cycling use and the most reliable performance for all precise device manufacturing works.
After the use of quite small size tube diameter of 26mm and extending electric wires for both 50mW pro red cross laser alignment and DC power supply, it is always allowing convenient installation, and no barrier red cross line source emission onto any raw material surface. When it gets the most special design of APC, ACC driving circuit board, without any affect by high temperature and serious electric current impact, this red alignment laser just achieves the most reliable performance and reduced possibility of tube burning out or damage. When it is operating safely with correct wearing of laser safety goggles, without any eye exposure to laser beam aperture, it just achieves highly secured and fine cross line measurement at great distance perfectly.
