Spherometers made by TRIOPTICS are used worldwide in hundreds of optics companies and laboratories for the precise measurement of the radius of curvature of concave and convex lenses. The radius of curvature is determined by the tactile measurement of the sagittal height of the curved lens surface...
Gonio-lens (1) is in the form of a cylinder truncated by an oblique plane whose base is a concave surface (2). The radius of curvature of this surface ensures a perfect contact with the cornea (13) of the eye, the surface of the oblique section being convex. The radius of curvature...

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...

Answer to: A plano-convex lens is to have a focal length of 40 cm. It is made of glass of index of refraction 1.65. What radius of curvature is...
A double convex lens (R1=R2=10cm) having focal length equal to the focal length of a concave mirror. The radius of curvature of the concave mirror View Solution The focal length of a concave mirror is 50cm. Where an object be placed so that its image is two times and inverted ...
From a set of previously derived equations for conic surfaces, we derived another set of equations from which the conic constant k and the paraxial radius of curvature r can be obtained, if at least three values of the longitudinal aberration X and their corresponding angles θ of the normals...
