What is an easy job to make clear and accurate enough dot projection at various work distances? Not easy to reach with a simple green laser pointer, in order to make long lasting and long distance dot positioning work, it would be a quite efficient job for users to operate a high density beam emitting tool of a 520nm green laser diode module. It always makes advanced use of an import 520nm green laser diode and a qualified optic lens inside a durable metal housing tube. In practical precise dot measuring work, only after its proper installation and correct use of output power, this direct diode emission made 520nm green dot laser brings users good direction, long lasting and high stability forest green dot projection onto all working surfaces constantly. 
When 520nm green laser diode module gets constant power source from a 5V, 9V 1000mA AC/DC adapter, owing to its acceptation of 100V to 240V operating voltage, it is always applied for various working environments. Being made with an import 520nm green laser diode within 5mW to 50mW, after basic use of a metal heat sink cooling system, it always gets good thermal emitting and increasing laser beam stability of at least 40%. In practical precise dot measuring work fields, this 520nm green dot laser still maintains ultra high stability and highly clear forest green dot projection within long lasting work time of 10 hours per day.
According to the advanced use of a qualified glass coated lens, without any effect by moisture, dust, rain, water of fog etc, this 520nm green laser diode module still makes sure of highly stable and reliable forest green dot projection in long lasting use. It should only be selected with correct output power on the basis of work distance and lighting occasion. When 520nm green dot laser makes proper installation onto those of industrial machine or device, within the longest work distance of 25 meters and multiple lighting occasions, it brings users quite satisfied dot measurement for laser marking machine, drilling system, military targeting, laser engraving, lab experiment and high tech work etc.
Within any limitation by long distance, high height and other hard reaching places etc, this accessory part of a 520nm green laser diode module enables quite easy installation, quick reaching and good direction forest green dot projection onto any raw material surface. It also allows freely adjusted laser beam focus and laser dot emitting direction, it brings users the best dot alignment experience for all labs, institutes and colleges etc. Whenever users are paying high attention to thermal energy hurt to eyes and wearing proper laser safety glasses, this green alignment laser still brings users easy and secured use for all working occasions.
