650nm red laser alignment is the most affordable line projection choice. From the first creation of laser diode technology, 650nm red laser diode is the first laser that is being designed and developed with the longest developing history. Owing to its mature laser diode technology and mass production, all kinds of laser gadget including red line laser alignment is always available at the most affordable price among all visible beam lasers. 650nm red laser is not as visible and bright as 532nm green laser, but it is always enough to provide moderate level of accuracy and precision red reference line on required fields. It is always enough for people to make line measurement and positioning on required surfaces of textile processing, garment making, stone cutting, wood processing or wooden board cutting machine etc.
In order to get different red reference line length at different targeting distance, red line laser alignment is always being designed with different laser degrees from 5 degrees until 120 degrees. The larger laser line degree has just got longer distance line length at targeted surfaces. For close distance targeting, a 5mW red line laser alignment is always customized to get 1 meter red reference line at 30 centimeter operating distance. The line projecting alignment laser is always being designed with fixed focus. Only if users know required line length at required distance, laser professionals will make correct calculation of required laser line degree.
The optic lens of red line laser alignment uses glass coated optic lens, which is much more efficient than commonly seen plastic lens. Usually glass coated laser lens is emitting more clearly visible red reference line than those of common ones. As a result, this genuine quality red laser alignment is always making the best line emitting result for both close distance and long distance line generating.
