Super-Spherotronic for high-precision measurements Super-Spherotronic is an automatic three ball contacting spherometer designed to meet the highest test plate calibration requirements. Being the most accurate instrument of our line of spherometers, Super-Spherotronic can measure the radius of curvature to an accuracy of 0.01%. To ensure that the highest available accuracy values of radius measurement are obtained, all Super-Spherotronic components have been optimized and perfected so that residual errors are negligible: • The mainframe components locating the probe are made of massive...

Rings and precision flats of Super-Spherotronic wolfram carbide (an extremely hard metal), while the probe center is an ultra-precision ruby ball. This completely eliminates any errors introduced by metallic probe centers used in other spherometers. • The probe itself is a high precision Heidenhain encoder, specifically selected for this use, having a total systematic and random error of less than 0.2 microns (0.000008“). • The test plates used for calibration of the instrument are manufactured to high quality standards to an accuracy better than 1/10 wave for sphericity. The test plates...

Spherocompact for production and quality control faces. The radius difference between the concave and convex test plates used in calibration is smaller than lambda/10. SPHEROCOMPACT 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. SPHEROCOMPACT with rings in wooden box • Easily removable rings of different diameters increase the versatility of...

tools and thus reducing subsequent rejected elements. Spherocompact which is an affordable but accurate instrument, can be used either for in-process measurement of lenses and polishing tools or for the calibration of test plates. Equipped with special rings, it can measure radius of cylindrical surfaces. ADVANTAGES Compared with other radius measuring methods (e.g. interferometers) the spherometric measuring method provides a multitude of advantages: R= R = Radius of curvature . D = Diameter of calibrated ring S = Sagital height . d = Diameter of ring ball ± = Correction for...
