Focal plane deviation

WebMar 31, 2024 · The focal plane is perpendicular to the principal axis of the lens . The distance of the focal plane from the lens is equal to the focal length of the lens . Note We know that every lens has two focuses , hence the number of focal planes will also be two ( according to the geometry of the lens) . JEE NEET Best courses for you Crash course WebThe focal plane in a camera is the surface the light is focused onto after passing through a photographic lens. In digital cameras the focal plane is the surface of the digital image sensor. Hence, the term “sensor plane” is used. Differences between the …
