Laser pointer performance large-scale concert

The laser pointer is a small tool, it can filter out the obvious light by using the power source, yes, it emphasizes things by illuminating everything with a tiny vibrant dot. Lasers can be divided into many categories, such as natural lasers, red lasers, and light blue-violet laser recommendations. Today, environmentally friendly green laser pointer have become the vane of all lasers with their luminous beam, clear perception, low cost and high quality. Environmentally friendly lasers have a variety of output capabilities, for example, some of them cover any range from 1mW to 1000mW, and people choose the appropriate type according to their own reasons. Laser systems at home and abroad are often used in conjunction with parallel data interfaces, USB interfaces and LAN (local area network technology) interfaces. The parallel data interface is "parallel". The "parallel" of the parallel interface does not mean that the interface side runs in parallel with the system bus data line, but refers to the parallel data line connected to the I/O device or the controlled object side. Parallel interface is suitable for short-distance transmission occasions, an improved two-way parallel transmission interface. Parallel data interface, easy to install and use, the highest transmission speed can reach 1.5Mbps. This is the current laser aiming or aiming laser device is mainly used as a 25-pin D-type connector for the parallel port interface. The customization requirements of the green laser pointer should be clearly stated in detail.

Material

The first laser pointer sold for hundreds of dollars, but for cheaper types, demand and improved manufacturing methods kept the price below 20 dollars. Other items include laser pointers, or at least parts, such as high powered laser sights for guns and projectors with built-in laser pointers. Our eyes are sensitive to light, which exists in a very small area of ​​the electromagnetic spectrum called "visible light". This visible light corresponds to the wavelength range from 400 to 700 nanometers (nm) and the color range from violet to red. The human eye cannot "see" radiation with wavelengths outside the visible spectrum. The visible colors from the shortest to the longest wavelength are: purple, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than visible violet light. Infrared radiation has a longer wavelength than visible red light. White light is a mixture of colors in the visible spectrum. Black is completely without light.
