Despite the name, most of these devices are meant for the dark: thermal monoculars with 384x288 and 640x512 pixel sensors, digital night vision devices with 4K recording, and models aimed at hunting. Traditional optics are represented by a 7x50 with BAK4 prisms, where the seven-times magnification and a 50-millimetre objective lens work in low light too. Thermal models are compared on the resolution of the sensor and the width of the field of view.
