First part includes the … 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 of a triangle. The lower end of the screw and those of the table legs are finely tapered and terminate in hemispheres, so … See more • Lapidary • Lens clock • Lens (optics) • Lensometer See more The spherometer directly measures a sagittal, h. Using the mean length between two outer legs, a, the spherical radius R is given by the formula: 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 … See more
WebSPHEROCOMPACT is an extremely accurate and easy to use instrument designed for saggita measurement of both concave and convex surfaces. • SPHEROCOMPACT is the first hand held spherometer with a high precision linear encoder which features bright digital readout, micron resolution and excellent absolute accuracy.
Webthe precision spherometers offer for comparable accuracy dramatically reduced costs. the measurement time for PC-controlled spherometers is a fraction of the time; needed to set up, to align and to take a measurement with interferometers. since the measuring procedure is so simple, no highly qualified personnel is required. WebJan 20, 2011 · If your spherometer radius is 49.96, change it to 49.97 and see what happens. Is that significant? Depends. But self-deception is never in order, imho. Science is all about self-doubt and testing. Repeatability is not accuracy. Accuracy is actually quantified uncertainty. Regards, Mladen
