WebFocal length = the distance from the subject to the lens + the distance from the lens to the camera sensor. You also need to understand if your lens is concave or convex to determine focal length. A convex lens (also known as a converging lens) and a concave lens (also called a diverging lens) focus light at different points. WebMar 15, 2024 · You can also collect more light by increasing the aperture of your optic. The trick with this, though, is that even as you increase the aperture, you have to make sure the focal length doesn't change. Often, a larger telescope will have a correspondingly longer focal length, which affects image scale, so the image becomes larger.
WebNov 22, 2015 · 1) If you increase the radius of one surface to a very large number, the lens becomes either a plano-convex or a plano-concave lens. For the moment, think only about a plano-convex lens, with R2 essentially infinite. Then. 1/F = (n-1) (1/R1) or F = R1 / (n-1) where n is the refractive index. 2) So, for n < 2, the focal length of a plano-convex ...
