The vertex of the lens surface is located on the local optical axis. For the curve $\gamma$ to coincide with some segment of a straight line or with an entire line it is necessary and sufficient that its curvature $k$ vanishes identically. You may imagine curvature as the inverse of the radius, but you can define it in other ways as well. The curvature of the curve is equal to the absolute value of the vector $d ^ {2} \gamma ( t)/dt ^ {2}$, and the direction of this vector is just the direction of the principal normal to the curve. 1.4K views. Principal Max/Min – Decides which direction on a surface has the smallest/largest radius (maximum/minimum curvature) and calculates the curvature in that direction.

Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. More Answers Below. Another approach is to look at the radius of curvature for which the focal shift will remain within a Rayleigh range of its undeviated position, i.e., within a distance that the beam will still appear to be focused.  The topography of the stressed structure including radii of curvature can be measured using optical scanner methods. For example, a circle with a radius of 1/2 metre has a curvature of 2 dioptres. That is, the curvature is κ = 1 R, {\displaystyle \kappa ={\frac {1}{R}},} where R is the radius of curvature (the whole circle has this curvature, it can be read as turn 2π over the length 2π R). It is denoted by R M, or M, or several other symbols. Besides, we can sometimes use symbol ρ (rho) in place of R for the denotation of a radius of curvature.
