Precise Work of 405nm Violet Line Laser Module for Laser Direct Writing

What is a good job to make precise and clear line indication for laser direct writing and photolithography, not relying on prior line drawing or printing work, it makes a better job to apply a direct diode emission made device of 405nm violet line laser module. It gets constant power source supply, employed by an import 405nm violet laser diode and a qualified optic lens with different fan angle, it can easily generate highly straight, fine and stable violet reference line onto multiple processing surfaces.
405nm violet laser line generator processed with a highly straight and fine violet line within 0. 5meter to 6 meters length, and freely adjusted laser line thickness. The single line marking is used for area exposure, pattern alignment, and boundary marking. Being used as an accessory part, it makes good job for precise line alignment for PCB photolithography, LDI laser direct writing alignment, alignment for microfluidic chips and masks, and alignment for microelectronic packaging and wafer edge marking etc.
