Night Vision Devices do not consist of :

Explanation

Night Vision Devices (NVDs) primarily function through two technologies: image enhancement (amplifying ambient light) and thermal imaging (detecting infrared radiation). A typical NVD consists of an objective lens, an infrared image converter tube (or image intensifier tube), and an eyepiece. NVDs are commonly designed in the form of a telescope (monocular) or binocular.

X-rays are high-energy electromagnetic waves with very short wavelengths, used for medical imaging and structural analysis. They are not utilized in night vision technology, which operates within the visible and infrared regions of the electromagnetic spectrum.
