WebMost objectives contain a colored band around the entire circumference of the body that indicates their magnification (Figure 7). For example, a yellow band denotes a 10X magnification. Numerical Aperture. The Numerical Aperture (NA) of an objective is a function of the focal length and the entrance pupil diameter. Large NA objectives … WebSep 9, 2016 · Indeed, this is how the focal length is defined. When we focus on nearby objects, the lens-to-sensor distance must be extended. We focus by racking the lens forward, extending its distance from the sensor. At life-size, magnification one, written as 1:1 or “unity, the lens extension is one focal length and the object-to-sensor distance will ...
