WebI am trying to figure out how big an object of, say, 50cm height at 100m distance and 600mm focal length would appear on a camera's sensor. The ubiquitous formula. object size in image = focal length * object size / object distance yields. object size in image = 600mm * .5/100 = 3mm What I am wondering: Are these 3mm entirely independent of ...
WebThe image distance is the distance from the thin lens to the image. The focal length is a characteristic of the thin lens, and it specifics the distance at which parallel rays come to a focus. Equation 1. Paraxial imaging equation. If the object distance is very large compared to the focal length it is considered to be at infinity.
