WebA spherometer is a measuring device which has a metallic triangular frame supported on three legs. The tips of the three legs form an equilateral … WebFigure 4: Spherometer Measure the distance from the center of the spherometer to one of the legs. You can measure the distance r with a simple scale. Place the spherometer on a plane mirror and record the reading. This reading on the micrometer corresponds to zero curvature. Place the spherometer on each lens and record the reading.
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.
WebMar 21, 2016 · Spherometers are useful particularly for measuring the ROC of convex surfaces for which there are no other simple inexpensive methods. There are 2 main variants the ring type (including truncated ring variants) and the 3 ball foot type. Fabrication errors include: 1) Unequal ball diameter size 2) Decentered depth measuring device axis kiwanis builders club websiteWebNov 22, 2016 · Determine the pitch and the least count of the spherometer [Art. 2.13 (c)] and record it step wise.
