532nm Laser Pens
Most green laser pointers on the market today have a wavelength of 532nm and is a DPSS (diode pumped solid state) laser. While this may seem like a minor difference, there is, in fact, a major difference between the two types of lasers. A 520nm green laser pointer has obvious improvements in power, stability, and durability compared to 532nm laser pointers. Naturally, the laser 532nm can also emit a clearly visible green beam light, but also can produce a number of beautiful patterns according to equipment setting, then making all kinds of beautiful occasion atmosphere.
