Spherometer base
WebA spherometer is a device that does just as the name suggests: it measures (ometer) a sphere (sphere). But what exactly would you measure on a sphere? You could measure its diameter or the circumference of a great circle, the surface area or the radius. But all of these measurements will change proportionally to the radius R of the sphere. WebBase of my 3" spherometer. Notice the circular grooves made with a circle cutter, the three feet, the pin of the indicator in the center, and the thumb set screw to keep the indicator from sliding out of the hole slowly during use. This base has holes drilled at 1", 2", and 3" diameter. In use, I have found that the 3" circle is the only size I ...

A spherometer basically is a precision instrument to measure very small lengths. Its name reflects the way it is used to measure the radii of curvature of spherical surfaces. It is based on the principle of screw. A base circle of three outer legs, a ring, or the equivalent, having a known radius of the base circle. See more A spherometer is an instrument used for the precise measurement of the radius of curvature of a sphere or a curved surface. Originally, these instruments were primarily used by opticians to measure the curvature of … See more The usual form consists of a fine screw moving in a nut carried on the center of a 3 small legged table or frame; the feet forming the vertices … See more Since the spherometer is essentially a type of micrometer, it can be employed for purposes other than measuring the curvature of a spherical surface. For example, it can be used to measure the thickness of a thin plate. To do so, the … See more The spherometer directly measures a sagittal, h.
