See the attached file. A spacer defines the air-gap distance between a lens and a flat surface. The corner of the spacer can be modeled as a circle with radius, r1. First a circular lens is used, and the "sag," or amount that the lens bulges out on the axis, defines the air gap distance by: sag = R - (R2 - (chord)2) ½ In th

If two circles with radii r and R contact at a point above a straight axis, what is the height, Δy, of contact (as a function of the curvature of the circles) above the axis. Please see the attached file for the fully formatted problem.
