WebbWatch on. The working principle of a standard camera involves using a lens to focus an image onto a light-sensitive material such as film or a digital image sensor. Light enters the camera through the lens, which is made up of a collection of tiny curved lenses that bend and focus the incoming light onto the image plane. WebbThe working principle is based on the generation of electron-hole pairs by the backscattered electrons which escape the sample and are absorbed by the detector. The …
