If users are looking for a high speed dot targeting without mistake, it is a very nice try to use Berlinlasers economy red dot laser alignment. It is making the best use of import 650nm red laser diode, owing to its long term development and mature laser diode tech application, this red laser module is just getting quite low price, while still keeping especially stable dot alignment in multiple dot targeting work fields.
Only after quite easy connect with a DC input power supply, Berlinlasers red dot laser alignment begins to generate immediate red reference dot targeting on different working surfaces. This red laser module is available with quite wide range output power from 5mW to 100mW, which is not only workable quite close distance, but also getting clear and quick enough red dot targeting at long distance and high lighting working occasion. This red laser alignment gets the most wonderful design of APC driving circuit board, together with metal heat sink cooling system, it is easily obtaining reliable dot alignment within 8 to 10 hours a day.
