WebFrom the Solve Type menu, select Marginal Ray Height and hit return. This is a “solve”, i.e. a calculation done by OpticStudio to solve for a property of the lens. In this case, we are setting the thickness from the back surface of the lens (#2) to the image (#3) such that the marginal ray which just hits the outer edge of the stop is ... 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 angle of the marginal ray reflecting off the secondary mirror is shown in Fig. 2(a) to be larger than the critical angle. This is in the case of an image plane at the vertex of the … Web3 Answers. Sorted by: 1. A lens with spherical surfaces (i.e. surfaces that are a segment of a sphere) does not focus all parallel light rays onto a single point. Instead there is a focal surface called a caustic. This causes spherical aberation. As long as the lens curvature is small, i.e. the ray is near to the optical axis (paraxial rays ...
