The desired optic lens of red line laser alignment is employing glass coated lens. Comparing with formally used plastic coated lens, once red line is pointed at quite long distance or continuing a quite long time, red line targeting is still keeping high brightness and no appearance of laser light decay in long term use. This 650nm red laser line generator is keeping extremely high linear quality and photoelectric ability, as a result, no matter what kind of working surface, within the allowing maximum work distance of 25 meters, this red laser module is easily obtaining super clear and visible red reference line in use.
No matter what kind of targeting surface, within quite wide range optic lens degree from 10 degree to 110 degree, red line laser alignment is getting different line length from 0.5 meter to 6 meters. At about 2 meters work distance from laser beam aperture to real working surface, red alignment laser line can reach as long as 6 meters after the selection of a 110 degree glass coated lens. This red laser line generator is getting the maximum output power of 100mW, which is able to generate super bright laser beam at several miles far away, however, in order to avoid laser light decay or blur in long distance, it is just a necessary to operate this red laser device at acceptable distance of 25 meters. In addition, once red laser beam is pointed under sunlight, nothing can be observed by human eyes. Users should always operate this red laser module avoiding sunlight, a correct power made red laser line is just making easy and clear line instruction effectively.
When red line laser alignment is being used in multiple work fields, once users are trying to get different line length, it is necessary for users to select correct output power and optic lens degree. In addition, within its quite compact size laser tube diameter of 16mm or 26mm, there is just enough space reserving as its cooling system, thus users have no need to worry about laser beam stability. It is also necessary part for users to wear a 650nm wavelength preventing laser safety goggles for any time of line targeting with a high power red laser device.
