Many friends don't even know that there are telescopes that can be used at night. In fact, it is not called a telescope, it is called a night vision device.

The function of a night vision device is not only to see far, but the most special thing is that it can be used at night - especially in the dark night, very clear!

The telescope we know can be used to see far, and the picture can be directly obtained through the eyepiece, but it is limited to daytime use. The weak light at night makes it difficult to see the details of things, and it is impossible to record the image.

But night vision devices are different. Night vision devices can be used both day and night, and have the function of magnifying the lens to observe the distance. The 4K high-definition night vision device lens and 8x digital zoom on the market can also record the viewed images in photo or video format.

The reason why the details of things can be seen clearly in a completely dark environment is because it relies on advanced infrared night vision technology. This technology can actively capture infrared light that is invisible to the naked eye at night, and then convert it into a picture that we can see on the display screen. This series of tedious steps are completed on this small night vision device, which can observe the details of things very well at night, especially for some friends who like to play outdoors.
