In fact, there are no night vision telescopes in the world. There are nitrogen-filled telescopes that can be used in low light. A telescope is an optical instrument that focuses light to form a direct image through refraction of a lens or reflection from a concave mirror, or through a magnifying eyepiece for observation. The use of a telescope is to bring the user closer to the target. Simply put, it magnifies the target for viewing without enhancing the light and penetrating capabilities. Therefore, the telescope does not have infrared night vision/see-through functions at all. What happened to the night vision goggles? Infrared night vision device is an electronic device that uses photoelectric conversion technology. Strictly speaking, a night vision goggle is not a telescope, it is an electronic device that uses batteries. There are two types: active and passive. The active one emits a beam of infrared rays, which shines on the object and then reflects back, which is equivalent to a flashlight; the passive one amplifies and converts the infrared rays emitted by the object itself into visible light.
