What is laser pointer?
What is laser pointer? The laser pointer is just laser transmitter, just like we used to play with infrared toys when we were young, just like an infrared sight. Laser colors include red, green and blue. When you open it, it will project a bright spot or light and point to the object.
Laser Pen principle
The laser pointer has red, green, blue, and purple light; different beam colors represent the colors emitted by lasers of different wavelengths. For red light: a solid-state diode pumped laser with a wavelength of 671 nm. For yellow light: The wavelength is 593.5 nm. Green light: 808nm infrared laser is used. For blue light: This is a 473nm blue laser manufactured by DPSS. Violet: Blue-violet laser diode with a wavelength of 405nm is used, which is a semiconductor laser and is close to the ultraviolet band.
