Marginal ray height
WebTaking the 0.707 ray as marginal, the primary becomes 141.4mm diameter f/2.79 mirror (the 0.707 ray focuses at the mid point of the original longitudinal defocus, 1.56mm inside the primary's paraxial focus). WebThe marginal ray (sometimes known as an a ray or a marginal axial ray) in an optical system is the meridional ray that starts at the point where the object crosses the optical axis, and …

WebIn complex objectives, the effective focal length is determined from the focus separation s from the last surface and the height of marginal ray h m on it, as ƒ=sD/2h m (FIG. 8). For closer objects, the focus forms farther away from the objective. how to make a clickable button in pygameWebThe marginal ray height on the rear doublet is small due to the proximity to the image plane.
