With the continuous development of science and technology, people's research and use of optics are becoming more and more common. Light of different wavelengths has different functions and uses on different devices. The VA-S01-L3B75 binocular laser rangefinder uses the characteristics of 905nm and 1535nm wavelengths to realize the laser ranging function.
(1)905nm wavelength laser
The main reason why laser rangefinders use 905nm wavelength lasers is that this wavelength of laser has great advantages in many aspects, so it has become the preferred choice of laser rangefinder technology. First of all, the 905nm wavelength laser is closer to visible light, which means it is more friendly to the human retina because the human eye is more sensitive to visible light. In addition, when this wavelength of laser propagates in the air, it is less affected by scattering, which is conducive to improving the accuracy of ranging. Moreover, the attenuation of 905nm laser in the atmosphere is relatively small, which means that it can propagate farther while maintaining sufficient intensity for accurate measurement.
In addition, 905nm wavelength laser also has its advantages in terms of technology and production cost. Due to the widespread application and mature production process of CMOS image sensors, the use of 905nm wavelength laser can make full use of this technical foundation, reduce production costs, and ensure product quality and performance. This is particularly important in the design and manufacture of laser ranging sensors because it is directly related to the market competitiveness of the product.
In summary, 905nm wavelength laser has become the preferred wavelength of laser ranging technology due to its relative safety to the human eye, good air transmission characteristics, and mature production process and technical foundation.
(2)1535nm wavelength laser
The main reason why laser rangefinders use 1535nm wavelength lasers is definitely that this wavelength of laser is safe for the human eye and has good transmission performance in the atmospheric environment.
Lasers with a wavelength of 1535nm are called eye-safe lasers. This is because lasers with a wavelength of 1.4-2.0 microns are almost harmless to the human eye, so lasers in this band are specially marked as eye-safe lasers. In addition, the 1535nm band is located in the atmospheric transmission window, and its absorption and scattering are only 1/50 of the output of 1.06um lasers, which is of great significance for long-distance effects, especially military applications. This type of laser usually uses erbium glass as the working medium because it can produce a wavelength of 1535nm, which is not only safe for the human eye, but also can more effectively penetrate environmental factors such as smoke and haze, making 1535nm lasers widely used in many fields.
Specifically, lasers with a wavelength of 1535nm have many advantages, including eye-safe characteristics, good beam quality, and stable single pulse energy, which are necessary for precise measurement and high-performance communication systems. In addition, the design of 1535nm lasers usually focuses on miniaturization and high efficiency to adapt to various more complex and harsh environmental conditions. These technical features make 1535nm wavelength laser widely used in ranging, radar, communication and other fields.
The VA-S01-L3B75 binocular laser rangefinder uses 905nm and 1535nm wavelength lasers, so the safety of the VA-S01-L3B75 binocular laser rangefinder is guaranteed. At the same time, it has good transmission performance, high stability, high precision, protection level IP66, small size, light weight, easy to carry, simple operation, and suitable for various complex environments. If you need a laser rangefinder, then the VA-S01-L3B75 binocular laser rangefinder is a good choice.
