How to choose the most suitable low-light night vision device?
In the previous article, we talked about 3 key parameters for purchasing digital night vision devices. Today, we talk about 3 parameters for purchasing low-light night vision devices (photo tube night vision devices). Yes, you heard it right, just looking at 3 parameters can help you easily buy a low-light night vision device.
low light night vision device
In fact, the purchase standard of low-light night vision devices is relatively simple, because the structure of this type of night vision device is relatively simple, and the function is relatively simple, only for viewing and use, of course, there are other night vision devices that have thermal image fusion function . No matter which function is integrated, it is still based on the basic framework of low-light night vision devices. Brilliance Tech is a professional manufacturer of low-light night vision devices.
The first parameter, image clarity.
Whether it is low-light night vision or other types of night vision, clarity is the first major reference. So what parameters are used to reflect clarity? The first is to look at the level of night vision devices, whether it belongs to the first generation of night vision devices, or the second generation of night vision devices, or the third generation of night vision devices, and higher-level night vision devices. Most brands of night vision devices will clearly indicate which category they are in the parameter performance of the product. Of course, the higher the level, the better the clarity. In addition to the level of the night vision imaging tube, it can also be identified by looking at the resolution, signal-to-noise ratio, and optical sensitivity. The resolution of the general second-generation night vision device is 48-65lp/mm (line pair), and the resolution of the third-generation night vision device is about 72lp/mm. The other two parameters will not be explained too much. The resolution and sensitivity of the night vision device refers to the resolution and sensitivity of the image intensifier tube. The signal-to-noise ratio is jointly affected by the image intensifier tube and the internal optical path design of the night vision device. It is precisely because of the above reasons that night vision devices with high resolution, high sensitivity and high signal-to-noise ratio will have a very high cost and a very high price.
The second parameter is the field of view.
The field of view of the current monocular low-light night vision device is generally 40-60, and the field of view of the binocular low-light night vision device is 40-120. This parameter is a bit far-fetched, because most night vision devices The minimum field of view is basically around 40. Of course, the larger the field of view, the better, but a large field of view means that some "sacrifices" have to be made in other aspects. For reference only, no hard cover required.
The third parameter, volume weight.
In fact, this is the appearance of the night vision device. Generally, the bulky low-light night vision device is also heavy, because the large volume means that the tube of the internal imaging tube is larger, and the low-light night vision device should still pursue small size, Due to the characteristics of light weight, you also need to pay attention to this when purchasing. If it is a 1000g thing hanging on the head, the neck can't stand it after half an hour.
Welcome to buy night vision goggles from Brillance Tech because they produce night vision goggles with high resolution, good quality and low price.
