Ray tracing involves two primary equations in addition to the one for calculating power. Equations 2 – 3 are necessary for any ray-tracing calculations. (2)y′ = y+u′t′ y ′ = y + u ′ t ′ (3)n′u′ = nu−yΦ n ′ u ′ = n u − y Φ where an apostrophe denotes the subsequent surface, angle, thickness, etc.

p(t) = e+ t (s-e) (now you know how to get s and e) •Typically weoffset the ray by half of the pixel width and height, i.e, cast the ray from the pixel center e s s-e incrementing (i,j) (0,0) Put it all together •We can represent the ray as a 3D parametric …
Lens approximations and equations - Opto E

The thin lens approximation requires the lens thickness to be considerably smaller than the radii of curvature of the lens surfaces: it is thus possible to ignore optical effects due to the real thickness of the lenses and to simplify ray-tracing calculations. Furthermore, assuming that both object and image space are in the same medium (e.g ...

A ray from the top of the object proceeding parallel to the centerline perpendicular to the lens. Beyond the lens, it will pass through the principal focal point. For a negative lens, it will proceed from the lens as if it emanated from the focal point on the near side of the lens. A ray through the center of the lens, which will be undeflected.
