Focal length in mirror
WebMirror formula is given as: 1 f = 1 v + 1 u. From the above equation, we get the focal length as: f = u v u + v. Where, f is the focal length of a concave mirror. u is the distance of object needle from the pole of the mirror. v is the distance of image needle from the pole of the mirror. The value of f will be negative. WebAccording to our science textbook focal length (f) of a mirror/ lens is equal to half its radius of curvature (R).Which means that there is a specific focal length for a given lens/mirror …

WebGSO's parabolic primary mirrors are perfect for those who want to build their own telescopes or replace mirrors in older ones. Ranging in aperture from 6” to 16” and offered in various f-ratios, these mirrors are made from optical grade BK-7 glass. All mirrors have a reflective aluminum coating with a reflectivity of 92-93%. WebDec 23, 2024 · The native focal length of the primary mirror of your scope is probably f/3 or f/4 - about 300 - 400 mm. The secondary mirror's negative curvature triples the focal length. So you do get 1200mm of focal length in a tube seemingly far too short...
WebAug 31, 2024 · Scope Focal Ratio (f/number): A lens or mirror’s focal length divided by its aperture. For instance, a telescope with an 80-mm-wide lens and a 400-mm focal length has a focal ratio of f/5. Eyepiece Focal Length: Eyepiece focal lengths are nearly always printed on the eyepiece itself and are labeled in millimeters. A telescope’s ...
