Graphic calculation of a biconvex lens; X optical axis, Z graph axis, Q graph centre, O1O2 centres of curvature of surfaces 1 and 2, r1r2 radii to points of refraction, p1p2 intercepts of incident and refracted ray on reference planes, p′1 p′2 intercepts of segment of ray within the glass, 1 and 2 lens surfaces and the corresponding graphs.
Lenses of a Huygenian eyepiece so drawn that the two curved surfaces have a common centre, p2 intercept of the ray in the eye lens, p′1 intercept of the ray passing from eye lens to field lens, p′4 intercept of the ray in the field lens, and p4 intercept of the ray below the field lens.
