Among all visible optical spectrum, the 532nm wavelength is just standing the middle part. After its projection into a uniform beam 532nm green line laser module, it is equipped with inner cooling system and a qualified optic lens with different fan angles inside its high duration anodized aluminum alloy housing tube. For the most important of all, owing to its ultra high brightness and high fineness green reference line projection with different line lengths and line fineness, cooperated with constant electric power source supply and ultra compact size tube design, this accessory part of a laser line generator enables quite easy reaching, quick response and ultra fine green reference line projection onto different working surfaces constantly.
The genuine use of a 532nm green line laser module applies a qualified separate crystal lens within 10 to 93 degree fan angles. When it projects non Gaussian distribution green laser beam, it also forms into highly uniform green reference line up to 85%. as a result, either it is pointing at close or long distance, it keeps work with the same line brightness from the middle part towards both ends, thus it is providing users quite satisfied line positioning results for those of long distance and high lighting working occasions as well. This laser line generator is especially applicable for those of longer distance, and fulfilling high level of accuracy line generation within the maximum work distance of more than 25 meters. 
The usual use of a uniform beam 532nm green line laser module has better contrast than red laser light in natural light and industrial lighting environments. The human eyes has a higher sensitivity to green light, and can clearly identify laser line even on strong light or dark workpiece surfaces. Comparing with formally used 405nm violet laser, green alignment laser light is less effected by dust or smoke, but keeping work with high penetration green laser light source emission at long extending distance. It is especially suitable for welding and cutting works. 
Laser cutting work with a 532nm green line laser module: metal sheet cutting, such as stainless steel, aluminum alloy, non metallic material cutting, such as acrylic, wood. When it projects a highly clear green reference line for the cutting  trajectory, replacing traditional manual marking to avoid human errors. Real-time display of the cutting path allows operators to adjust the position of the workpiece quickly so as to reduce material waste. Suitable for high-speed cutting equipment (such as fiber laser cutting machines), the green alignment laser line response speed is synchronized with the movement of the equipment to improve processing efficiency.
