What is the 303 laser pointer?

The 303 green laser pointer produces a powerful beam. The beam provides a strong safety function. This handy device allows you to adjust the beam intensity for various applications. The green light beam produced by this laser pointer can harm human eyes. It can usually be seen at night without additional dust or spray. With this 1000mW beam, you can easily point to the constellations in the night sky, just like pointing to the wall of a room. At the farthest distance, it can reach 1000 meters. The measuring power of the collimating diode blue laser pointer exceeds 1,500 mW. However, the claimed power of the "laser pointer" product also includes infrared power (DPSS technology only) still exists in the beam (the reason is described below). The problem of comparison based on the visible blue component of the DPSS laser still exists, and the information is usually unavailable. Due to the use of the optimized DPSS module neodymium harmonics and frequency multiplication conversion efficiency is low. The percentage of IR power converted to a 473 nm blue laser is usually 10-13%, which is about half that of a green laser; 20-30%).
