green laser pointer can be used as the teaching baton.
Experimental simulation, I understand the method to eliminate errors, and mastered the basic use of the microcontroller. Research projects and a comprehensive understanding of the development of the laser rangefinder, structure, principles and the existing problems, mastered the essential skills of scientific research. Small size of semiconductor lasers, light weight, high reliability, high conversion efficiency, low power consumption drive power can be directly modulated structure is simple, inexpensive, safe to use, and its broad range of applications. Such as optical storage, laser printing, laser typesetting, laser rangefinder, barcode scanning, industrial detection, test and measurement instrument, laser display, stage lighting and laser show, laser level and a variety of marking location. green laser pointer can be adopted as some other kinds of indication and irradiance tool.The assembling area of green laser pointer is within the workshop
Some unique advantages of semiconductor lasers make it very suitable for military applications, such as field ranging, guns, etc., aimed at the shooting simulation system, blindness, guided submarine communication, fuses, security and other. Due to the use of ordinary electric bulbs drive, portable weapons and equipment configurations possible. Has been developed and put on the market, the band of the semiconductor laser 370nto, 390r Shan the 405r Shan, 430nto, 480hm, 635r dish, 650hm, 670hm, 780hm, 808nm, 850hm, 980rm, 1310hm, 1550hm, etc., which 1310hm 1550hm main for optical fiber communications. 405nm in a 670n. To visible light 780nm a 1550hm, for the infrared light, 390rm a 370hm ultraviolet wavelengths. green laser pointer can be used as the wireless present.
The laser is a high intensity light radiation devices, high-power lasers can be used for cutting and welding of metallic materials, so the laser on the human body, especially the human eye, serious injury, be extremely careful when using. International uniform classification and unification of safety warning signs on the laser, the laser is divided into four categories (Classl ~ Class4), a class of laser is safe, the two types of lasers on human lighter injuries, the three categories above lasers have a serious injury, when used, should pay particular attention to avoid direct human eye. The basic principles of laser ranging technology. The laser rangefinder is the use of monochrome and coherence of the laser, strong direction stare, to achieve high-precision metrology and testing, such as measuring length, distance, speed, angle, and so on.
