In process of ultra clear, precise and bright dot measuring work in laser marking fields, not able to rely on any manual or mechanical dot aligning work, it would be a much better solution for engineers and factory workers to operate a high energy density light emitted tool of a 405nm violet laser diode module. 405nm falls within the near-ultraviolet band, boasting high photon energy and strong non-metallic absorption, enabling clear marking without high power. Marking exhibits significant color difference, high contrast, and sharp, unblemished letter edges. Whenever violet dot laser alignment makes proper use of output power and properly adjusted laser dot diameter, not limited by operating distance, height and other complex working environments, it is able to work with clear, precise and good direction dot alignment for multiple marking works conveniently.
On consideration of high beam stability and long operating time lasted violet light and violet dot projection, this 405nm violet laser diode module has been made with an import 405nm violet laser diode and a qualified glass coated lens. It is available with wide range output power of 50mW to 100mW and higher power up to 150mW to 500mW, configured with a metal heat sink cooling system inside a durable anodized aluminum alloy housing tube, it gets larger space leaving for tube heat dissipation, and achieves ultra long time lasted violet light and violet dot projection as long as 24 hours per day. Furthermore, when violet dot laser alignment makes proper use of output power and operating voltage DC power supply, it can also instruct workers and engineers to make noncontact, no mistake and no barrier dot alignment in long term use.
In process of long operating time lasted dot positioning work, 405nm violet laser diode module enables extremely low thermal effect, cold marking prevents burning or scorching of heat sensitive materials, such as plastics, leather, and fabrics, avoiding yellowing and deformation. Being made with a qualified glass coated lens and adjustable focus optic lens design, every time highly powerful and intense violet light is concentrated from beam aperture, this violet dot laser alignment is converting into an increasing accuracy and brightness violet dot with small spot size, excellent collimation and narrow divergence angle. It is assuring clear and precise marking of micro-characters, high-density QR codes, and fine textures, meeting high-precision marking requirements.
Owing to special ultra violet laser light emission, 405nm violet laser diode module can excite fluorescent materials to create invisible anti-counterfeiting marks that are invisible to the naked eye under normal conditions but visible under ultraviolet light, suitable for high-value-added products such as tobacco, alcohol, pharmaceuticals, and cultural and creative products. Being made with ultra compact size tube, violet alignment laser is easy to embed in small marking machines, portable devices, and automated production lines. It has low power consumption and long lifespan, with maintenance and procurement costs far lower than deep ultraviolet laser equipment.
