Small focal length vs large focal length
Webb12 sep. 2014 · Focal length is a technical characteristic of a lens that directly influences its angle of view, i.e. how much of the entire field of view it will project onto the sensor. Large focal length results in a small angle of view, which means the … WebbFocal Length The focal length of a microscope objective is typically between 2 mm and 40 mm. However, that parameter is often considered as less important, since magnification and numerical aperture are …
