What is an efficient job to make ultra clear and precise dot indication at longer distance than formal hand reaching? It might be far more enough than formal hand reaching, not easy to reach with a simple green laser pointer or other prior dot positioning work, it would be a much better solution to operate a high energy density beam emitted tool of a 515nm green laser diode module. Cooperated with its inner thermal emitting system and qualified optic lens inside different dimension metal housing tube, only if this ultra compact size tube made 515nm green dot laser gets proper installation or integration, this accessory part is able to make ultra clear, precise and long time lasting dot indication onto multiple raw material surfaces conveniently.

Owing to the adoption of wavelength of 515nm green light band among all visible optical spectrum, human eye visual sensitivity is high, and the subjective brightness is about 5 times that of red light at the same power. When 515nm green laser diode module applies an import 515nm green laser diode within 5mW to 100mW and high power up to 150mW to 200mW, it gets different laser safety classes of IIIa, IIIb, and IV. Cooperated with an inner metal heat sink cooling system inside a durable anodized aluminum alloy housing tube design, the genuine use of a 515nm green dot laser alignment gets superior nice heat dissipation and thermal conductivity, and ultra long time lasting green reference dot projection within long lasting work time of 10 hours per day.
Whenever glass coated lens made 515nm green laser diode module gets quite low laser beam divergence of less than 1.5mard fan angle, and special tem00 laser beam mode, no matter it is pointing at close or long distance, it still makes sure of ultra compact size and precise green reference dot projection at different work distances. In process of long time lasting dot measuring works, the green alignment laser dot is small after long distance transmittance, such as 10 meters, and maintaining high energy concentration in continuous use.
Cooperated with different operating voltage electric power source, such as 5V, 9V, 12V 1000mA AC/DC adapter, not spending extra time on battery change, the usual use of a 515nm green laser diode module always makes sure of long time lasting green laser light source emission, ultra precise and bright green reference dot generation for multiple application fields, covering industrial and manufacturing, intelligence device, laser medical therapy and biotech, military targeting etc. Whenever green alignment laser is operating with basic obeying of laser safety issue, after proper wearing of 515nm wavelength preventing laser safety glasses, it just makes sure of easy, secured and noncontact dot measurement for all working occasions conveniently.
