Once you are trying to make highly precise dot indication at different work distances, it is not an easy job to get ideal dot alignment accuracy as expected. However, under operation with continuous technical innovation of 650nm red laser diode tech and and qualified optic Lens laser, Tech engineers have just created are quite practically used device such as a 650nm red laser be module. It emits the most visible and the brightest red laser light source from a 650nm red laser diode. Owing to the special use of a glass coated lens inside the durable anodized aluminum alloy housing tube, it always gets excellent thermal emitting and highly reliable red dot projection in long lasting use. 
The basic adoption of a 650nm red laser diode module is different from a simple red laser pointer. It projects a similar red laser light source as a laser pointer, however not any longer limited for temporary positioning work, this red dot laser has to be made with even longer time and longer distance positioning work. As a result, it gets the basic use of a metal heat sink cooling system cooperating with a durable anodized aluminum alloy housing tube. This 650nm red dot laser has just achieved excellent thermal emitting and thermal conductivity. Usually it allows long lasting red reference dot projection within daily operating time of ten hours. It still gets no effect by increasing temperature and serious electric current impact as well.
According to the easy connect of AC/DC adapter, after accepting wide range electric current of 100 to 240 voltage, the usual use of a 650nm red laser diode module is applicable for multiple countries and regions. It is applying an import 650nm red laser diode within 5mW to 100mW as beam emitting source. Whenever it projects highly visible red laser beam emitting source at several miles far away, on consideration of high accuracy dot measurement, this 650nm red dot laser only allows constant red dot projection within ten hours per day. It always gets no effect by increasing temperature and serious electric current impact as well.
On condition that 650nm red laser diode module gets proper installation onto any other industrial machine or device within freely installed distance of three meters, it brings users the easiest reaching and the longest lasting red dot projection onto any vertical or horizontal work surface. It brings users non contact, no mistake and long lasting dot projection for multiple raw material processing works. Once it is getting constant electric power source supply and the proper adjustment of both laser beam focus and laser dot emitting direction, after immediate laser light source concentration, this alignment laser just brings the users increasing accuracy and brightness dot projection at great distance and formal lighting working occasion. Users should just take basic laser safety measure and wear correct laser safety glasses, it brings the users easy free and secured dot measurement in long lasting uses effectively.
