Whenever users are looking for an easy operating and highly fine line alignment, not limited by long distance or any other manual labor force input, it is always making an easy job after the use of a high purity beam emitting tool of 635nm red line laser module. It is projecting the purest red laser light from 635nm red laser diode. Owing to its low laser beam divergence and special use of separate crystal lens, it is always performing with highly fine and bright red reference line projection from beam aperture. In a large variety of industrial and high tech line positioning work fields, after correct use of output power and optic lens, without the use of sunlight, this red laser line generator always makes sure of increasing accuracy and fineness red line alignment at various work distances. The practical line alignment work with 635nm red line laser module is different from any other manual line drawing or printing work. It is operating easy and quick after its connects with an external AC/DC adapter. Employing an import 635nm red laser diode within 5mW to 100mW, only after its correct use of a 5V, 9V 1000mA DC power supply, it is able to make continuous red laser beam emission, and highly clear red reference line projection at various work distances. In occasion that it is avoiding use under sunlight, high power red laser is just making clear line alignment within the maximum work distance of 25 meters.Being made with the best quality separate crystal lens, comparing with formal glass coated lens or plastic coated lens, this 635nm red line laser module is performing with highly uniform distribution red laser light emission. It is also performing with the same line brightness from middle part towards both ends, without laser light decay or blur in continuous use. Within wide range optic lens degree of 10 degree to 93 degree, after basic measurement and experiment of technical data, this laser line generator allows correct use of separate crystal lens degree, and makes sure of increasing accuracy red line alignment for all precise device manufacturing work fields.Without any serious relying on manual labor force input, 635nm red line laser module always makes easy and quick line indication onto any vertical or horizontal surface. It is also allowing quite easy screw of adjustable focus optic lens and high speed red laser light concentration, and assuring no mistake and no barrier line alignment for a lot of application fields, including military targeting, lumber machine, sand milling, textile garment processing and high tech work fields etc. When high power red alignment laser is selecting for long distance and high lighting, only after correct wearing of laser safety goggles and avoiding eye exposure to beam aperture, it always makes sure of highly secured and fine red line alignment in all application fields perfectly.
