In order to get highly precise line projection at close distance, not easily relying on any manual or mechanical line aligning device, it should be quite marvelous experience to adopt Berlinlasers 5mW green line laser alignment. It projects the most easily absorbed and sensitive color green laser light from middle wavelength of 532nm green DPSS laser part, which is able to work with the clearest green reference line in close distance effectively. This 5mW green line laser alignment enables easy use after connect with 5V 1000mA DC input power supply. Comparing with formal alkaline battery power made green laser pointer, it leaves larger inner tube space for metal heat sink cooling system and APC driving circuit board. In formal continuous line alignment work, it maintains up to 85% beam stability under work within 8 to 10 hours per day. When green laser module gets proper installation and adjustment of laser beam focus and laser line targeting direction, it fulfils no mistake line projection for all industrial line aligning work fields perfectly. Technical data: Item: Berlinlasers 5mW green line laser alignment Wavelength: 532nm Laser class: IIIa Optic lens: 10-110 degree glass coated lens, separate crystal lens Adjustable focus: yes Applications: laser cutting, sand milling, textile garment processing, high tech etc http://www.berlinlasers.com/532nm-green-line-projecting-laser-alignment
