Two types of radius gauges. A radius gauge, also known as a fillet gauge, [1] is a tool used to measure the radius of an object. [2]Radius gauges require a bright light behind the object to be measured.
A spherometer is an instrument used for the precise measurement of the radius of curvature of a curved surface. Originally, these instruments were primarily used by opticians to measure the curvature of the surface of a lens .

BS 8888 performs three fundamental tasks : Unifying all the ISO standards applicable to technical specification; Giving an index of ISO standards involved with different principles of technical product specification (TPS);
Lens clock. A lens clock is a mechanical dial indicator that is used to measure the dioptric power of a lens.It is a specialized version of a spherometer.A lens clock measures the curvature of a surface, but gives the result as an optical power in diopters, assuming the lens is made of a material with a particular refractive index.
