Any time highly precise dot measurement is in need for those of industrial processing works, not easily relying a simple laser pointer or other manual dot projecting tool, it should be a much better substitute for engineers and professionals to operate a highly intense beam emitted tool of a 405nm violet laser diode module. It keeps work with highly intense and powerful violet laser light generation fro an import laser diode directly. Featured by its short wavelength of 405nm, cooperated with basic thermal emitting system design inside a highly durable housing tube, this direct diode emission made violet dot laser alignment enables highly intense and concentrated violet laser light emission, and efficient conversion of increasing accuracy and stability dot alignment for all industrial precise processing works conveniently. 
After its easy connects with an AC/DC adapter, without spending extra time on alkaline battery change, 405nm violet laser diode module always enables highly powerful violet laser light source concentration. The short wavelength of 405nm can be focused to sub-micron level violet laser dot projection, with concentrated energy density, enabling high-precision micro/nano-scale processing. When it applies an import 405nm violet laser diode within different output power range of 50mW to 100mW and 150mW to 500mW, according to the adoption of a metal heat sink cooling system design inside a durable anodized aluminum alloy housing tube, violet dot laser alignment always enables superior nice heat dissipation and ultra stable violet dot indication as long as 10 hours per day. 
Whatever raw material surface it is pointing, 405nm violet laser diode module maintains high material absorption rate for polymers, semiconductors, and some metals. It gets higher absorption rate than other long wavelength lasers, resulting in higher processing efficiency and a negligible heat-affected zone. Equipped with a qualified glass coated lens and an adjustable focus optic lens in front of laser beam aperture, once it gets immediate violet laser light concentration, violet dot laser alignment enables low dot alignment positioning errors, allowing for precise control of the processing area and preventing damage to surrounding materials. It can be adapted with precision motion platforms and vision positioning systems, supporting various industrial processing equipment and automated mass production.
General applications in industrial processing:
Micro/Nano Fabrication: Etching of microstructures in semiconductor chips, fabrication of fine circuits on PCBs, and molding of micro-sensor components.
Material Modification: Micro-melting modification of metal/non-metal material surfaces (improving hardness and wear resistance), and activation of polymer material surfaces (enhancing adhesion).
Precision Welding: Spot welding of micro-electronic components (such as chip pins and micro-battery tabs), and precision welding of biomedical devices (such as micro-catheters).
3D Printing Assistance: 405nm violet alignment laser makes precise exposure point positioning in photopolymer 3D printing (adapted to rapid curing of photosensitive resins), and precise contour positioning for micro-part printing.
