WebThe resolution of an optical imaging system – a microscope, telescope, or camera – can be limited by factors such as imperfections in the lenses or misalignment. However, there is a principal limit to the resolution of any optical system, due to the physics of diffraction. WebAug 2, 2024 · The third method is to define a tolerance on the focal length, most often in terms of percentage. For example, a lens with a 500mm focal length may have a +/-1% tolerance which translates to 495mm to 505mm. Plugging these focal lengths into the thin lens equation allows fabricators to derive the mechanical tolerance on the radius of … preinvestigation
