WebFor optics like convex lenses, the converging point of the light exiting the lens is on the input side of the focal plane, and is positive in optical power. For concave lenses, the focal point is on the back side of the lens, or the output side of the focal plane, and is negative in power. WebIf such a camera is used with the lens that was previously described as being able to resolve 100 lp/mm, the system will be limited by the lens and not the camera. This means that a camera that was capable of an optical resolution of 145 lp/mm is lens-limited to an optical resolution of 100 lp/mm.
