2) So, for n < 2, the focal length of a plano-convex thin lens will be greater than the radius of curvature, and for n > 2, the focal length will be less. Most optical materials have an index of refraction in the range of 1.3 to 1.7 for visible light, so for most lenses, the...
The surface curvature of cylindrical optics is typically spherical and they tend to have a plano-convex or plano-concave design, coming in circular, rectangular, or square profiles. These are used for a broad range of applications across the full spectrum of industry and research. Common uses of...
