Different from a simple used green laser pointer, once dot alignment work is processing for a quite a long time or long distance, it is for more enough to reach with manual labor force input. Thus it is a quite a nice solution for users to operate a high brightness device, such as a 532nm green laser diode module. It keeps works with highly visible and intense green laser light source emission from a 532nm green DPSS laser system. Among all visible laser devices, owing to its low laser beam divergence and quite special TEM00 laser beam mode, either dot alignment work is processing at the close or long distance, this 532nm green dot laser is always making sure of highly precise and highly clear green dot projection at long extending distance continuously.The basic use of green laser diode module is always continuing for quite a long time. The major part of a metal heat sink cooling system has just got even better thermal emitting that formally used air or water cooling system. After the configuration of the durable anodized aluminum alloy housing tube, available with different dimensions of 16mm and 26mm diameter design, this 532nm green dot laser just obtains superior nice thermal emitting and thermal conductivity, and enables highly reliable green reference dot projection within daily operating time of ten hours, without any appearance of laser light decay or blur in proper use.On condition that 532nm green laser diode module applies a qualified glass coated lens and glass window, after strict laser beam stability test and aging preventing tests up to 24 hours, it is achieving high quality green laser light source emission at long extended distance. Usually it is pointing under quite harsh working occasion, such as moisture, rainwater, fog or dust, the special use of a glass window still makes perfect protection of this alignment laser from any possibility of laser light decay or blur. As a result, within wide range output power of 5mW to 100mW, this 532nm green dot laser is not simply used for close distance and inner room working conditions, but also making quite satisfied the green dot projection at long extending distance of 25 meters and multiple highlighting working occasion as well.Different from any prior dot positioning work, only according to the real work distance and required dot diameter design, this 532nm green laser diode module should only be selected with correct output power and proper mounting onto any other machine or device. It enables easy installation and quick response green dot projection onto any vertical or horizontal work surface. The unique adoption of adjustable focus optic lens has just assured highly concentrated green laser light source emission and highly precise dot projection at greater distance and highlighting working occasions. Whenever users take basic laser safety measures and wear correct laser safety glasses, industrial stabilized alignment laser just makes easy, long lasting and good direction dot alignment for all application fields.
