In those of industrial and high tech precise dot measuring work fields, cooperated with advanced 515nm green laser diode tech and a qualified optic lens inside a durable metal housing tube, laser tech engineer has just developed a professional dot measuring tool of a 515nm green laser diode module. It gets near middle wavelength among all visible optical spectrum, featured by its low laser beam divergence fan angle and special tem00 laser beam mode, either it is pointing at close or long distance, a correct output power made 515nm green dot laser just makes sure of ultra clear, precise and good stability green reference dot projection at long extending distances conveniently.

Being made with an external AC/DC adapter as its electric power source, comparing with a simple green laser pointer only used for temporary dot positioning work, the usual use of a 515nm green laser diode module is able to work with long time lasting green laser beam and green dot projection from beam aperture. For the most important of all, configured with an inner metal heat sink cooling system inside a durable anodized aluminum alloy housing tube, it gets superior nice heat dissipation, ultra stable green reference dot projection within wide range operating temperature, different humidity and other working environments as well.

In various industrial and high tech precise dot measuring work fields, on consideration of ultra clear and precise dot indication onto different working surfaces, 515nm green laser diode module applies a qualified glass coated lens and glass window in front of laser beam aperture. It projects highly clear and precise green reference dot at long extending distances. When it is equipped with adjustable focus optic lens, this low laser beam divergence fan angle made 515nm green dot laser gets highly concentrated forest green laser beam emission, and increasing accuracy and brightness green dot alignment at longer lasted distance and ambient lighting occasions etc.

Application in industrial fields:

Precision dot alignment and positioning. Compact size tube made 515nm green laser diode module is used for electronic component assembly (such as chip packaging, SMT patch), mechanical component installation, such as machine tool guide rail calibration, automatic production line station alignment. Green laser dot is clearly visible, which is convenient for operators to align tiny components with high level of accuracy up to 0.1mm, and improving assembly efficiency and consistency.

Laser marking and engraving. Green alignment laser dot is used for permanent dot identification of the surface of materials such as metal, plastic, and ceramic, such as product serial number, QR code, pattern engraving etc. The green alignment laser wavelength has a high absorption rate for some non-metallic materials, fast marking speed and small heat-affected zone, which is suitable for high-precision and low-damage marking needs.

3D scanning and measurement. High brightness green laser light source and green reference dot can be used to object contour scanning in industrial automation (such as robot vision guidance, size detection), reverse engineering modeling. The reflectivity of green light on diffuse reflection surfaces is better than that of infrared light, and the spot imaging is clear. With the camera, high-precision 3D point cloud data acquisition (accuracy can reach micron level) can be achieved.
