Comparing with formal 532nm green DPSS (diode pumped solid state) laser, the creation of 520nm green line laser module should be super great technical revolution of green laser technology. It is keeping direct green laser light emission from inner 520nm green laser diode, it is always providing the most stable and reliable green reference line projection for long time and extreme temperatures etc.
The import 520nm green laser diode is accepting wide range operating temperature within -10 degree to 45 degree Celsius, which is also getting at least 40% improvement of laser beam stability in continuous line projecting work. According to the adoption of quite durable aircraft used aluminum alloy housing tube, it is bearing quite serious occasion of mechanical moving or calibration.

Either it is required to make line alignment for close distance, long distance or other complex working environments, 520nm green line laser module is fulfilling the need for different users. Beginning from 5mW to 50mW, supported by 5V or 9V DC input power supply, it is able to work with continuous forest green reference line projection on various targeting surfaces. Within wide range electric current within 100V to 240V, laser line generator is applied for any working occasion, also getting featured advantages of overheating and over current protecting functions.

In special working occasion of the most accurate line alignment at quite long work distance, 520nm green line laser module would be equipped with the best quality separate crystal lens. It generates non Gaussian distribution green laser beam from laser beam aperture, which is also generating highly fine green reference line. It keeps work with up to 80% beam uniformity, but also keeping the same brightness from middle part towards both ends. Under correct selection of optic lens degree, this laser line generator is assuring no mistake line alignment onto targeting surfaces.

Under occasion of formal accuracy line alignment, 520nm green line laser module can be made with formal plastic coated lens. Available with different fan angle from 10 degree to 110 degree, it is able to generate different line length at a given work distance. On basis of quite easy adjustment of laser beam focus and line targeting direction, green reference line is always making no mistake and no barrier line aligning result onto targeting surfaces.
