Digitronic spherometer; consists of 3 basic parts; 1 is the ball ring which is a precisioin jig ground fixture with ultra precision balls; measurement device is a precision linear position encoder w/0.0001 inch resolution, 3-is the display unit which is an electronic counter and calculator; item gives precision measurement of lens-concave, lens-convex, flats, balls, spheres, spherical segment, spherical zone, centicular shapes, comparator agains master optics, item provides a method of measuring curved surfaces w/extreme accuracy to 0.0001 in. On sagitta height range porm 0.600 in.
No other part numbers with same form, fit, and function found.
A gage used to obtain precise measurements or variances between objects electronically. It may include a power supply, computer, measuring amplifier, or probes. The output may be in analog, digital, opto-electronic, or printed form. See also analyzer, surface finish, contact.
