The use of laser pointer

The use of a green laser pointer enables crystal injection of larger wavelengths.

 The resulting light is then refracted from the mirror to achieve the optimum wavelength, making the distant light more visible. Compared to previous laser pointer, it uses much more powerful radiation and is more powerful.

The structure and composition of the blue laser pointer is the same as that of the early green laser pointer. These are nothing more than twice the laser of a green laser pointer. The light produced is ideal for all types of white retractable screens.
