Magnification of Infrared Night Vision and Digital Night Vision
Because the magnification of the low-light tube is about 0.5, it is not easy for the lens to achieve a large magnification, and it is generally a fixed magnification, such as 1x, 3x, 5x, etc.
The digital night vision device itself will also have a fixed magnification, but at the same time there will also be a digital zoom. For example, Alfa's new multi-function third-generation digital night vision device DB550L itself has a magnification of 5 times and a digital magnification of 1-4 times, which means that the overall magnification range of this digital night vision device is 5-20 times. There are also digital night vision imaging systems with a magnification of approximately or greater than one, so generally speaking, with the same magnification lens, the magnification of a digital night vision device will be twice that of an infrared night vision device, such as an infrared night vision device with a magnification of 5 times. The lens of the vision device is 10 times larger than that of digital night vision, which is very important.
