A laser pointer is a tool that uses a Laser pointer. The length that can be displayed is relatively long, it can replace pointers and other pointers, and can also be used as an indicator when playing movies, ppt, etc. The laser light emitted by the laser pointer is a solid-state laser, so the light-emitting principle of the laser pointer is the light-emitting principle of the solid-state laser. The solid-state laser in the laser pointer is a laser diode. A remote control is a device used to remotely control a machine. Modern remote controls are mainly composed of integrated circuit boards and buttons, and there are many types of remote controls. We mainly discuss infrared remote control.
With the advancement of technology and time, the laser pointer has developed into a small high-tech product, not only for guidance, but also for continuous expansion. The laser light emitted by the laser pointer is a solid-state laser, so the light-emitting principle of the laser pointer is the light-emitting principle of the solid-state laser.The solid-state laser in the laser pointer is a laser diode.
The visible light wavelengths that can be seen by the human eye are arranged from long to short, in order of red, orange, yellow, green, net, blue, purple, and the wavelength range, and the main component of the emitting part is an infrared light diode. This is a special light emitting diode. Because its internal material is separated from ordinary light-emitting diodes, it is a special light-emitting diode. The infrared wavelength of the widely used infrared light diode is about 940nm, the shape is the same as that of the ordinary infrared light diode, but the color is different.
The difference between a laser pointer and a remote control is essentially the difference in the principle of light output, that is, the difference between a laser diode and an infrared diode. This is the difference between laser diodes and ordinary photodiodes.
