If line aligning work is processing for quite long time, without any relying on manual labor force input, it is perfect choice to try Berlinlasers 515nm green line laser alignment. It is applying an import 515nm green laser diode and metal heat sink cooling system inside its anodized aluminum alloy housing tube, after proper use of 16mm and 26mm diameter metal housing tube, it is assuring excellent thermal emitting, and highly stable forest green line projection within constant work time of 8 to 10 hours. After its proper installation onto industrial machine or device, without any manual labor force input, it always makes no barrier and no decay light line projection under any other harsh occasion of moving or shocking etc. This 515nm green line laser alignment applies qualified glass coated lens and separate crystal lens. It gets wide fan angles of 10 to 110 degree, and Gaussian or non Gaussian distribution infrared laser beam. It is projecting a high linear quality and highly fine green reference line within 0.5 meter to 6 meters. Without any mistake caused by manual operation, when 515nm green laser module makes correct use of output power and optic lens degree, within freely installed distance of 3 meters, it makes sure of no barrier line projection at various work distances perfectly. Technical data: Item: Berlinlasers 515nm green line laser alignments Output power: 5mW to 50mW Optic lens: 10-110 degree glass coated lens, separate crystal lens Adjustable focus: yes Applications: lumber machine, laser cutting machine, sand milling, textile garment processing etc https://www.berlinlasers.com/515nm-forest-green-line-laser-alignment
