If line measuring work is processing at much longer distance and high lighting than formal occasion, it is an easy and efficient job to apply a 50mW green laser line generator. It is able to work with the most sensitive color and easy absorbing green laser light from middle wavelength of 532nm green DPSS laser. When it gets the lowest laser beam divergence of less than 1mrad, green laser module is just achieving highly fine and straight line generation in distance. The usual use of 50mW green laser line generator is applying for various working environments. Designing with metal heat sink cooling system and APC driving circuit board inside durable metal housing tube, it is obtaining perfect thermal emitting and highly stable green line alignment in continuous use. It should only be selecting with correct optic lens degree, after proper installation and adjustment of laser beam focus, unless it is pointing under sunlight, green line laser makes highly fine and precise line alignment in distance perfectly.
