What is an efficient job to make clear and accurate dot indication at a longer work distance than formal hand reaching? It is not able to rely on a simple laser pointer or manual dot projecting work at all, but making even better job with a highly intense beam emitted tool of a 405nm violet laser diode module. It is widely used for a lot of industrial precise machinery processing work fields. The 405nm wavelength falls within the near ultraviolet range, with higher photon energy, allowing for focussing into a smaller spot size. It is suitable for high-precision inspection and micromachining. On condition that ultra compact structure made 405nm violet dot laser makes proper installation or integration with other industrial device or equipment, it enables easy reaching, highly precise and clear violet reference dot projection at a long extending distance constantly.
The real use of a 405nm violet laser diode module applies an import import 405nm violet laser diode within 50mW to 100mW and high power range of 150mW to 500mW as its beam emitting source, which is in need to make long time lasting dot projection work as expected. It applies an inner metal heat sink cooling system and APC, ACC driving circuit board inside a durable anodized aluminum alloy housing tube. Besides the adoption of a qualified laser diode, it is also coupled with high performance driving circuit board, which offers strong anti-interference performance, excellent consistency, and a long service life of more than 10,000 hours in use. When violet dot laser module is working together with other industrial device or instrument, it can work continuously within 8 to 10 hours per day, and still maintains ultra high laser beam stability of up to 85% in continuous use.
Typically 405nm violet laser diode module is made with ultra compact size tube, available with 16mm, 18.9mm and 26mm diameter for different output power range. It gets featured advantages of ultra-small footprint and high compatibility, which are easily integrated into various industrial equipment, convenient to use, and do not occupy excessive space. According to real work distance, 405nm violet laser alignment enables correct use of output power and equipped operating voltage DC power supply, it is suitable for high precision industrial dot measuring application fields greatly. The short wavelength excels in industrial applications requiring high precision, such as semiconductor photolithography, enabling high-precision line exposure and uniform exposure, meeting the high-precision requirements of microelectronic component manufacturing.
In addition, the practical use of a glass coated lens 405nm violet laser diode module is compatible with special materials. It offer excellent dot marking and curing performance for certain materials, such as some plastics, resins, and photosensitive resins, making them difficult to replace with other wavelengths. It also gets unique interaction with biomolecules and biomarkers, making it widely used in biomedical testing instruments. It can excite fluorescent markers, enabling the detection and imaging of biological tissues and molecules, playing a vital role in the R&D and production of medical devices.
Application in industrial precise machinery processing works:
Material Processing and Marking: 405nm violet laser diode module can be used for laser marking on some plastics, resins, and other materials, accurately engraving patterns, text, and other markings on their surfaces. It can also be used for photocuring. The 405nm wavelength can rapidly cure certain photosensitive resins, finding applications in 3D printing and UV ink curing.
Semiconductor and Electronics Manufacturing: 405nm violet alignment lasers play a key role in laser direct imaging (LDI) equipment used in industrial PCB production. Their high power output enables submicron exposure accuracy, enabling precise engraving of complex circuit patterns, improving the yield rate of PCB production, and shortening exposure time. Measurement and Control: It can be used in laser tool setters. For example, the HPS-LCA100 high-precision laser tool setter utilizes a 405nm violet laser diode module. Its shorter wavelength enables higher measurement accuracy and improved anti-interference capabilities, enabling stable, rapid, and precise tool measurement under the complex working conditions of CNC machining centers.
Biomedical Testing: The 405nm wavelength resonates with absorption wavelengths of substances such as DNA and RNA, and also matches the excitation wavelengths of various biomarkers. Violet alignment laser is commonly used in fluorescent dye excitation, cell imaging, flow cytometry, and Raman spectroscopy, helping researchers observe and analyze biological tissue samples.
