Whenever precise dot measuring works is in serious need, either pointing at close or long distance, engineers and professionals would prefer to operate a high density light emitted tool of 445nm blue laser diode module. It applies an import 445nm blue laser diode and a qualified optic lens inside a high duration metal housing tube. It always has high absorption rate of high reflectivity materials, such as copper, gold, silver and aluminum etc. When blue dot laser alignment gets constant power source supply, available with wide range output power and basic thermal emitting, it is resulting in high contrast, clear characters, no whitening, and no blurring, solving the problem of difficult coloring of highly reflective metals in traditional laser marking.
Owing to the adoption of a short wavelength of 445nmm, the blue light emitted from a blue laser diode module is easy to focus, resulting in small and uniform dot-shaped spots, enabling micron-level micro-marking, ultra-small characters, and fine QR codes, meeting the high-precision marking requirements of precision electronics and micro-parts. Available with minimally low heat affected zone, concentrated energy and narrow heat diffusion range from a blue dot laser alignment can prevent ablation, deformation, and excessive oxidation and blackening, ensuring that thin-walled parts, soft metals, and precision components are not damaged by high temperatures.
Cooperated with a qualified glass coated lens and adjustable focus optic lens, after its immediate blue laser light concentration, this 445nm blue laser diode module gets immediately focused blue dot generation at greater distance. It gets uniform dot-matrix marking patterns, sharp edges and strong three dimensional effect on metal parts, no scorching, yellowing, or cracking on plastic and glass surfaces. After quite easy screw of adjustable focus optic lens in front of laser beam aperture, blue dot laser alignment gets immediately focused blue light, and converts into an increasing brightness and accuracy blue dot projection at greater distance of 25 meters and even higher lighting occasions as well.
Owing to its ultra compact size tube design of 16mm, 18.9mm and 26mm diameter, 445nm blue laser diode module enables easy installation or integration, suitable for automated production lines. It is resistant to vibration interference, can be directly integrated into online marking machines, robotic arms, and assembly line stations, suitable for continuous batch production. Available with low power and energy consumption, when blue alignment laser enables slow light decay, strong long term industrial stability, and simple maintenance. After its correct use of output power and operating voltage DC power supply, it makes sure of clear and precise laser dot marking on a lot of raw material surfaces, including highly reflectivity metals, precision micro-marking, thin-walled parts, glass and ceramics, and fine dot/character marking on ordinary plastics.
