How can glass lens 650nm red line laser module work at different work distance?

No matter line projection work is processing at close or long distance, or other hard reaching places, it is not a good job to still adopt a formal manual line drawing or printing work at all. At the same time, after continuous technical innovation of advanced 650nm red laser diode tech, not simply made into a red laser pointer, it is developing into a quite practically used device of a 650nm red line laser module. On condition that it gets constant power source supply and proper mounting onto other industrial device or equipment, without any serious relying on any manual labor force input, this laser line generator just begins to work with constant red laser beam emission and high precision line indication for multiple raw material processing works. 
The usual use of a 650nm red line laser module is always working for a quite long time. It is a key issue to maintain its stable and reliable line generation in long lasting use. The basic use of an import 650nm red laser diode is assuring increasing laser beam stability of at least 40%. In addition, after its special use of a metal heat sink cooling system inside a high duration anodized aluminum alloy housing tube, in practical precise line positioning work, this direct diode emission made laser line generator has just achieved excellent thermal emitting and thermal conductivity. It also enables long lasting red line alignment within 10 hours, and up to 85% laser beam stability under proper use.
On the basis of a qualified glass coated lens within wide fan angles of 10 to 110 degree, under operation with a series of strict laser beam stability test and aging preventing test up to 24 hours, the real line generation with a 650nm red line laser module is working well with excellent laser light cycling use, and highly reliable red line generation in long lasting use. It gets different line lengths of 0.5 meter to 6 meters. In practical industrial and high tech precise line positioning work fields, this laser line generator is operating easy and quick as an accessory part, which is able to make highly clear and quick response line indication for laser cutting, saw mill, lumber machine, laser car wheel alignment, laser medical therapy and high tech work etc.
Not relying on any manual labor force input, no matter it is pointing at close or long distance this 650nm red line laser module just enables the most convenient installation and the easiest reaching of red line source indication in continuous use. It allows freely adjusted laser line fineness and line emitting direction, which just enables the highest level of accuracy line generation within the longest extending distance of 25 meters. On condition that laser users are paying high attention to thermal energy hurt to eyes and wearing proper 650nm wavelength preventing laser safety goggles, without any eye exposure to laser beam aperture, this alignment laser brings users easy and secured line generation in long lasting use effectively.
