Why would a green laser pointer be made?

At present, with the development of multimedia players, multimedia players using hard disks, micro hard disks, and memory cards are emerging in an endless stream, and the remote controls used for operation are also diverse. Usually, the remote control equipped with it uses the emitted red light as the remote control laser. The remote control distance is short and the human eye can recognize it relatively low, so it is not easy to achieve a good effect of attracting attention. The traditional red light multimedia remote control pointer can no longer meet the requirements of the development of multimedia equipment. In order to overcome the short remote control distance and the low recognition of the human eye aligned with the beam, a green remote control laser pointer with a long controllable distance and high beam recognition is not only different from the ordinary red laser pointer, its wavelength Shorter, just within the visible range of the human eye, and the output brightness is much higher than that of the red laser.
