Unlike the middle wavelength of 532nm green DPSS laser, the creation of a 505nm green laser diode module applies advanced semiconductor laser diode tech, cooperating with basic thermal emitting design and qualified optic lens, it is able to work with ultra nice thermal emitting and stable green laser beam and green reference dot projection at long extending distances. According to its special use of high sealing and high strength materials made, this green laser gets perfect protection of its internal components and ensures that the module works stably in different working environments.
General inside the durable anodized aluminum alloy housing tube, 505nm green laser diode module adopts a metal heat sink cooling system. It generates heat and increasing temperature when it is working. However, owing to its superior nice thermal emitting and thermal conductivity, usually it enables long time lasting green dot projection within 8 to 10 hours per day, and still maintains ultra stable and reliable green dot projection as expected. It keeps work with superior nice laser beam stability and ultra long time lasting green dot indication.
Not as bright as a 532nm green DPSS laser, the 505nm wavelength is still in the green spectrum range, and the human eyes are highly sensitive to light of this wavelength, thus it has excellent visual recognition in bright or dim environments. Besides its basic adoption of external AC/DC adapter as its electric power source, it also gets special use of APC, ACC driving circuit board inside the tube. It enables long time lasting green laser beam and green dot projection, without any effect by increasing temperature and serious electric current impact as well.
Owing to the use of advanced manufacturing technology and high quality optical component, such as glass coated lens and glass window in front part of a laser beam aperture, this 505nm green laser diode module is maintaining high transmittance green laser light emission, and high laser power stability in continuous use. When it is pointing under quite harsh working occasion of moisture, dust, rain, or fog etc, it gets no effect, and still maintains ultra clear and precise green dot projection within both of long time lasting and long distance dot positioning works. This 505nm green dot laser gets ultra low laser beam divergence radiation, thus which can maintains good directionality during propagation and reduce energy dispersion.
