Not simply relying on prior line printing or line drawing works, whenever users are trying to make quick and accurate enough lien projection onto various targeting surfaces, none of manual or mechanical line aligning tools can be comparable with a 520nm 5mW green line laser module. It is not the same as a formally used 532nm green DPSS laser system. When it is keeping highly bright forest green laser light from 520nm green laser diode, after basic equipment with inner metal heat sink cooling system inside highly durable metal housing tube, this laser line generator is just workable with highly clear and stable green reference line projection in constant use.

The genuine line alignment work with 520nm 5mW green line laser module is different formal a quite simple line drawing device. After correct use of an external DC input power supply with 5V operating voltage, it is keeping work with continuous green reference line projection from beam aperture. It is accepting wide range electric current, without any limitation of thermal emitting space and extra time spending on battery change, this laser line generator is always workable with constant green reference line projection from beam aperture. This laser line alignment tool is able to work within daily operating time of 8 to 10 hours, under operation with enough time leaving for laser tube cooling down, it is keeping highly reliable performance and long serving lifetime in use.
When line alignment work is processed for quite long time, not the same as a formal laser pointer device, 520nm 5mW green line laser module gets excellent use of inner metal heat sink cooling system and APC, ACC driving circuit board. Under operation with constant output power and electric current supply, without any worrying about laser light decay or blur in constant use, this line laser alignment tool achieves good laser light cycling use and the clearest green reference line projection onto any vertical or horizontal surface constantly.
On basis of easy selection of qualified glass coated lens or separate crystal lens, within 10 to 110 degree fan angles, 520nm 5mW green line laser module obtains different line length and line thickness in use. For the most important of all, when users are making easy screw of adjustable cylindrical lens, this alignment laser gets the most focused laser light and the finest green reference line projection in use. Usually within the maximum installation distance of 3 meters and easy adjustment of line targeting direction, it achieves no barrier and no mistake line projection perfectly.
