Proper Operation Instructions for Laser Rangefinders
Internationally, there is a unified classification and standardized warning sign for lasers. Lasers are categorized into four classes (Class 1 to Class 4). Class 1 lasers are harmless to the human body; Class 2 lasers cause minor harm to humans, while Class 3 and above lasers can result in severe injury. Special caution must be exercised during use to avoid direct exposure to the human eyes.
In the early 1990s, major European and American companies successively commercially produced semiconductor laser diodes, bringing a revolutionary advancement to the practical application value of lasers. Other types of lasers are greatly limited in application due to their complex laser generation mechanism, oversized volume and weight, and high power consumption. The emergence of semiconductor lasers has perfectly solved these problems. As semiconductor laser technology matures further and costs gradually decrease, its production scale and application fields continue to expand. Judging from the current development pace, it boasts extremely promising application prospects.
Semiconductor lasers feature small size, light weight, high reliability, high conversion efficiency, low power consumption, simple driving power supply, direct modulation capability, compact structure, low cost and safe operation, supporting an extremely wide range of applications. Typical scenarios include optical storage, laser printing, laser typesetting, laser ranging, barcode scanning, industrial detection, testing and measuring instruments, laser display, medical equipment, military applications, security monitoring, field exploration, construction leveling and marking instruments, laboratory and teaching demonstrations, stage lighting and laser performances, laser level rulers and various marking and positioning devices.
The unique advantages of semiconductor lasers make them highly suitable for military applications, such as field ranging, firearm aiming, firing simulation systems, dazzling jamming, submarine communication guidance, fuze devices and security defense. Powered by ordinary batteries, they enable the deployment of various portable military devices.
