When line indication work is processing at different work distances, not able to rely on any manual or mechanical line aligning work, it would be a quite efficient job to operate a high density beam emitting tool of a 515nm green laser line generator. Being made with an import 515nm green laser diode and a qualified optic lens inside a durable metal housing tube, it is working well with high quality forest green laser beam emission, and ultra fine and bright forest green line projection at long extending distance. Any time this ultra compact size tube made 515nm green laser module makes proper installation to desired machine or device, it is able to make quick response and long lasting green line alignment for all raw material processing works constantly. 
Designed with an AC/DC adapter, comparing with a simple green laser pointer with alkaline battery power source, the usual use of a 515nm green laser line generator is always working for a quite long time, and still maintaining its stable and reliable green line projection in use. It is applying an import 515nm green laser diode within 5mW to 50mW as its beam emitting source. Owing to the special use of a metal heat sink cooling system design, after getting even better thermal emitting than formal air or water cooling system, this 515nm green laser module is working well with good laser beam stability and ultra long time green line alignment for all precise machinery processing works. 
According to quite special use of a qualified glass coated lens within 10 to 110 degree fan angles, after special use of a glass window in front of laser beam aperture, the usual use of a 515nm green laser line generator is performing well with high transmittance and high density forest green laser beam emission at several miles far away. Whenever it projects high linear quality and highly straight green reference line within 0.5 meter to 6 meters lengths in use, only after correct selection of both of output power and optic lens fan angle, this 515nm green line laser is able to make high precision and high brightness green line indication for multiple industrial and high tech fields constantly. 
Being made with APC, ACC driving circuit board, within wide range output power of 5mW to 50mW, this 515nm green laser line generator keeps work with constant green laser beam and green line projection, and achieves long serving lifetime of more than 8,000 hours in proper use. On condition that it projects powerful green laser radiation and thermal energy hurt to eyes, after correct wearing of laser safety glasses and avoiding eye exposure to beam aperture, this green alignment laser just brings users easy and secured use for all application fields effectively.
