WebA spherometer is used primarily to measure the curvature of objects such as lenses and curved mirrors. This example came from the U.S. Naval Observatory. It was made by Alvan Clark & Sons for the U.S. expeditions to observe the 1874 transit of Venus. It has only a horizontal scale and no vertical scale common to most spherometers. WebApr 12, 2024 · The spherometer is an instrument that measures the radius of curvature of a spherical surface using the micrometre screw principle. This consists of a graduated disc in 500 divisions, say, which is turned above by a milled head. The screw is rotated precisely such that for every turn of the disc, say 0.5 m m , it progresses.

WebA spherometer is an instrument used to measure the radius of curvature of a spherical surface. It usually consists of a small, pointed metal probe that is placed against the surface to be measured and a calibrated scale that indicates the radius of curvature. Electronic Spherometer: It is an instrument that measures the curvature of a surface. WebJan 20, 2011 · The precision in the depth gauge is now (after the above) going to determine the accuracy of the spherometer in use, as the leg measurement is over a long span and can be determined to a few parts in a 100,000. heather st johns fc twitter https://stork-net.com
