If there is not a good method for users to get clear enough line alignment at quite longer distance than formal hand reaching, it is just a very nice choice to make good use of Berlinlasers red laser line generator. it is a direct laser beam emission line alignment tool, owing to the use of import 650nm red laser diode and good equipment of metal heat sink cooling system, it is easily obtaining highly stable and reliable red reference line targeting in long term use.
The selection of glass coated lens within wide range lens degree from 10 degree to 110 degree just makes red laser line generator obtain different line length in use. When users are knowing enough about required line length, line thickness and work distance from laser beam aperture, laser tech engineer can recommend users correct output power and optic lens degree made red laser module. In addition, these red laser modules is very compactly design, allowing easy installation and adjustment, and finally obtain quick and no mistake line alignment effectively.
