When users are getting serious need of ultra clear and precise dot indication at a longer work distance than formal hand reaching, not easily relying on a simple laser pointer or manual dot projecting tool, it would be a much better solution to make use of a highly intense beam emitted tool of a 405nm violet laser diode module. It applies a short wavelength 405nm violet laser diode as its beam emitting source and a qualified glass coated lens inside a durable metal housing tube. Commonly violet dot laser gets constant electric power source supply and proper integration with industrial machine or device, not limited by long distance or high height, this short wavelength violet laser light can be focused to sub-micron level spots, precisely targeting micro-machining areas, meeting the micro-nano scale requirements of machining.
In process of long term constant dot generation work, 405nm violet laser diode module applies an import 405nm violet laser diode within 50mW to 100mW and high power range of 150mW to 500mW as its beam emitting source. It should be working for even longer lasted violet laser beam and violet laser dot projection than a formally used violet laser pointer. As a result, when it adopts different dimension tube diameter of 16mm, 18.9mm and 26mm design, owing to its larger space leaving for inner metal heat sink cooling system, this direct diode emission made violet dot laser alignment enables good heat dissipation and ultra long time lasted violet dot generation for all dot positioning works.
Within the shortest time consumption, only after quite easy connects with 5V, 9V or 12V 1000mA AC/DC adapter, 405nm violet laser diode module allows highly concentrated energy emission and short duration of action result in negligible damage to surrounding materials, preventing thermal deformation of mechanical parts from affecting precision. Equipped with APC, ACC driving circuit board, whatever output power it is selected, violet dot laser alignment keeps work with constant violet laser beam and violet laser dot projection, and long serving lifetime of more than 8,000 hours. It keeps work with uniform energy distribution in the dotted laser spot, combined with a vision positioning system, enables micron-level positioning errors, improving processing consistency. Featured by high absorption rate for commonly used mechanical materials, such as metal, stainless steel, titanium alloys, polymers and ceramics, it offers processing efficiency superior to long-wavelength lasers.

405nm Violet Laser Diode Module Used for Laser Marking Works
Whenever advanced 405nm violet laser diode is applied for the creation of a professional dot measuring tool, it is cooperated with a qualified optic lens and basic cooling system inside a highly durable metal housing tube, thus designed and manufactured into a professional dot measuring device, such as a 405nm violet laser diode module. Based on correct use of output power and connects with DC power supply, not seriously relying on any manual labor force input, this ultra compact structure made violet dot laser enables easy carrying and easy integration, and high efficiency laser marking work on materials such as plastics and resins, enabling precise engraving of patterns, text, and other markings on their surfaces.
Comparing with any other visible laser devices, the basic use of a violet laser diode module applies a much shorter wavelength of 405nm, which belonging to the near ultraviolet laser range, has a shorter wavelength, allowing it to be focused into a smaller spot size. When it applies an import 405nm violet laser diode within 50mW to 100mW and high power up to 150mW to 500mW, either it is pointing at close or long work distance, it is achieving higher marking accuracy and suitable for fine marking applications, such as engraving tiny logs on electronic components. In addition, owing to its high photon energy, this 405nm violet dot laser alignment tool also allows for specific photochemical reactions with some materials, disrupting the bonds between atoms or molecules, causing them to vaporize and evaporate, achieving marking. With a minimal heat-affected zone, it represents a “cold process” and is suitable for marking heat-sensitive and easily deformed materials.
Based on the adoption of a qualified glass coated lens and glass window inside a durable anodized aluminum alloy housing tube, this 405nm violet laser diode module is not only projecting high energy density and highly powerful violet laser light source at long extending distance, but also converting into ultra compact size and bright violet reference dot projection at long distance and and high lighting occasions as well. After quite easy screw of adjustable focus optic lens, every time violet dot laser alignment tool gets highly concentrated laser light source, it also assures increasing accuracy and brightness dot projection at even longer distance and higher lighting occasions. It gets wide material compatibility, which is suitable for marking a variety of materials, including glass, plastic, IC chips, and PCBs, with particularly good results on white plastics and heat-sensitive plastics, meeting the marking needs of various industries, including electronics, pharmaceuticals, and packaging.
Only if 405nm violet laser diode module gets proper connects with AC/DC adapter, it can make excellent marking results onto different raw material processing surfaces. It produces clear, durable marks with strong wear and corrosion resistance. For products requiring anti-counterfeiting or traceability, it can be used to mark information such as QR codes and barcodes, resisting tampering and wear. Owing to its ultra compact structure design, this violet dot laser module is highly compatible, and reliable, which can be easily integrated into various laser marking systems, minimizing space requirements. Power can be adjusted to suit different application requirements, offering high adaptability. Any time this alignment laser makes proper integration onto laser making machine or device, it can assure fast marking, the marking of large numbers of parts in a short period of time, meeting the demands of industrial mass production. It also offers low maintenance costs, a long service life, and 24/7 operation.
