Not the same as other type of other larger size laser devices, green laser pointer is just specially designed in type of quite compact portable pen style. It is always very easy to carry to any place, and make the easiest and the most convenient operation in all occasions. However, any type of laser radiation might be hazard to human eyes, thus laser pointer operators should be cautious enough with any type of invisible and visible laser irritation, and finally enjoy the greatest laser fun in all occasions.
Owing to quite special laser beam transverse mode of TEM00, green laser pointer is always able to make the lowest laser beam divergence of as low as 0.1mard. Whatever kind of targeting places, it can generate the most visible laser beam and the lowest size green dot in use. As a result, this great laser pointer presentation tool is always able to make super wonderful laser beam projection on all targeting surfaces perfectly.
Not the same as other type of laser diode direction beam emission, 532nm green laser pointer selects crystal beam emitting, thus it might produce even larger energy in operation. As a result, laser owners should always obey the correct operation rule. Each time laser pointer pointing time should not exceed 15 seconds, otherwise, it might affect the practical serving lifetime of this green laser pointer.
Any type of laser devices might be hazard to eyes retina. It is not clever idea to make direct pointing of bright green laser beam to human eyes. Retina might be seriously hurt by powerful laser radiation and laser reflection. It is also not allowed to make presentation with green laser pointer in public. Even though user are only operating very low powered laser pointer, it is still necessary to make active measures, and remember to wear laser safety goggles so as to make the most perfect protection of eyes precisely.
