In order to make highly clear dot alignment, no matter it is pointing at close or long distance, it is always making good job with a high purity beam emitting tool, such as a 635nm red laser diode module. It is projecting at least 3 times brighter red laser light than formal 650nm red laser. On basis of its selected output power within 5mW to 100mW, on basis of its low laser beam divergence of less than 1mrad and special TEM00 laser beam mode, it is working well with highly clear red laser light emission and the brightest red dot alignment at various work distances.
The advanced use of a qualified glass coated lens is cooperating with a glass window, after up to 24 hours aging preventing and beam stability tests, this 635nm red laser diode module is working well with high transmittance red laser light and highly clear red dot alignment within the maximum work distance of 25 meters. Only after its easy adjustment of both dot diameter and dot emitting direction, it brings users low cost, high stability and long lasting red dot alignment perfectly.
