While, before choosing an ideal green laser pointer, you have been surfing online or seeking for suggestions with someone else. A qualified laser pen should not only get reliable quality, but also reliable after sale services. Low price is not the only one choice for users. It should be designed with elegant and durable shell, long lasting and good quality green laser beam and green laser dot emission of laser beam aperture.

Comparing with other visible laser devices, among all visible optical spectrum within 405nm to 1064nm laser devices, 532nm green laser pointer is standing among the middle wavelength range. It projects the most visible and the most easily absorbed green laser light of middle wavelength of 532nm green DPSS (diode-pumped solid-state) Laser system. Not projecting laser light directly via a laser diode, it is projecting even more visible and brighter green laser light, thus getting even better performance than any other visible lasers with the same output power.

On consideration of laser operating safety, in majority countries and regions, 532nm green laser pointer is only allowing laser safety class of IIIa, not exceeding 5mW. If users are getting serious need of such laser device, it only allows proper output power of 1mW and 5mW. When it is flowing into laser market, it has just passed through a series of strict laser beam stability test up to 24 hours. In practical operation of a green laser pen, only after easy press of on/off button on the front part of laser tube head, it begins to work with highly visible green laser light emission at several miles.

Not the same as industrial stabilized laser module device, the genuine use of a 532nm green laser pointer should be power off after a few seconds work. The inner part might be getting increasing temperature, thus after constant green laser dot projection within 30 seconds, it should be power off so as to make sure of perfect cooling down of laser tube, and maintain excellent performance in formal laser beam targeting.
