If you are seriously puzzled about how to get clear enough line alignment at quite long work distance, it is just the time to use Berlinlasers green laser line generator. It is very easy to operate, when it is getting quite easy connect with a DC input power supply, it can make immediate and high brightness green reference line targeting on desired working surfaces. Unless sunlight working occasion, when users are selecting green laser module within 5mW to 100mW, it is just able to make super clear green laser line alignment under multiple working conditions, including close distance, long distance, high lighting etc.
Green laser line generator gets the good use of qualified glass coated lens, the desired green line is not only available with high linear quality, but also generating different line length and line thickness so as to get clear enough green line targeting in multiple working fields. This green laser module is a very nice accessory part, making great help for laser cutting machine, military targeting device, laser image processing system etc. When green laser module gets proper installation and adjustment of both line targeting direction and line thickness, it gets no mistake line alignment all the time.
