Good Use of 445nm Blue Crosshair Laser Module For Precision Manufacturing Laboratories Different from any prior cross line drawing or printing work, it makes a good job to apply a Berlinlasers 445nm blue crosshair laser module for precision manufacturing laboratories. It projects ultra fine and straight two perpendicular blue liens at long extending distances, unaffected by long distance or high height. Being made with basic thermal emitting system and APC, ACC driving circuit board inside a durable metal housing tube, it enables easy installation, high stability and high precision blue vertical and horizontal lines generation at longer lasted distance conveniently. Being made with a qualified glass coated lens with 10, 15 and 110 degree fan angles and adjustable focus optic lens, cross line laser module enables highly concentrated blue laser light emission and efficient conversion of ultra clear and fine blue cross line projection. It makes good job for microchip and micro-component assembly and positioning, small device performance testing benchmark calibration, and is suitable for micro or nano fabrication experiments. https://www.berlinlasers.com/445nm-50mw-80mw-100mw-blue-crosshair-laser-module https://www.berlinlasers.com/oem-lab-lasers/cross-line-laser-modules
