How does glass coated lens 635nm red line laser module work at various distances? from Daniel Smith's blog

In various industrial precise line measuring work fields, different from any prior line drawing or line printing work, a lot of factory workers and engineers would prefer to make clear line alignment with a 635nm red line laser module. It is keeping work with highly pure and bright red laser light emission from a 635nm red laser diode. Being made with a qualified glass coated lens with wide fan angles and constant power source supply, no matter it is pointing at close or long distance, it always makes sure of easy mounting, quick reaching and high precision red line alignment onto any raw material processing works.

Not the same as prior line drawing or printing work, either it is pointing at close or long distance, this 635nm red line laser module is working well with the purest and the brightest red laser light emission from a 635nm red laser diode. Available with quite low laser beam divergence and special TEM00 laser beam mode, whatever kind of working surface it is pointing, it is projecting extremely clear and fine red reference line from laser beam aperture. As a results, either it is pointing at close or long distance, unless it is pointing under sunlight, this laser line generator is able to make highly precise line generation for a lot of raw material processing works effectively.

When 635nm red line laser module applies a qualified glass coated lens with wide fan angles of 10 to 110 degree, different from any prior line positioning work, it should only be selecting with correct output power and optic lens fan angle. It projects highly straight and fine red reference line within 0.5 meter to 6 meters. Usually within the maximum work distance of 25 meters, unless it is pointing under sunlight, this red laser line generator is able to make highly precise red line indication for a lot of application fields, including laser cutting for stone, wood, steel, garment, saw mill, lumber machine, laser car wheel alignment system and high tech work etc.

Designed with different dimension and durable metal housing tube, available with electric wires for both 635nm red line laser module and DC power supply, it always allows the most convenient installation, and the easiest reaching of red line alignment onto any vertical or horizontal surface. Owing to special use of adjustable focus optic lens, after immediate red laser light focusing, this industrial alignment laser achieves increasing accuracy and fineness red line alignment at even longer distance and higher lighting occasions. When users are paying high attention to laser safety issue and wearing correct laser safety goggles, without any eye exposure to laser beam aperture, it always brings users highly secured line generation in constant use.
