Spherometer accuracy
WebAt its simplest, a spherometer is just a ring with a known inner diameter and outer diameter with a depth indicator in the middle. When placed on a convex or concave spherical surface, you immediately have all three points. Ask Question Comment Download Step 1: Materials You can use almost any materials, to any dimension. WebThe Spherometer is a device use in measuring the radius of curvature of a spherical surface. For an example, it can be used to measure the thickness of a microscope slide or the depth of depression in a slide. Even the curvature of a ball can be measured using a Spherometer. The Spherometer consists of a micrometer screw threaded into a small ...

WebA spherometer is a device which does exactly as it says: a sphere (sphere) it measures (ometer). It is a device used to measure the curvature of a sphere. See below: The spherometer has three straight legs equally spaced out, like the corner points of an equilateral triangle. A fourth leg is at the centre of the triangle and is adjustable. WebFor example, if a tolerance of 0.02% is required in the radius of curvature R=10" using a spherometer with arms of length 3.5", the required accuracy in reading the sagitta must …
WebZeiss, of Jena, constructs a very accurate spherometer having a ring with an inner circular knife edge for convex surfaces, and an outer circular knife edge for concave surfaces. Webusing spherometers the radius can be accurately measured before polishing, when a correction of the lenses is still possible. the accuracy of measurement is directly traceable to international standards, since Trioptics spherometers are calibrated with (NIST and NPL) certified test plates.

WebA spherometer is used to measure the radius of curvature of a spherical surface. Most lenses have surfaces that are either spherical or close to it. For such surfaces, a spherometer provides a simple way to verify that the curvature is correct. WebSome of the widely used modi cations of the common spherometer are: Ball Spherometer: Accuracy of measurement requires the legs of the spherometer to have sharp tips, which can damage the surfaces under study. Blunt tips may save the surface but compromise on the accuracy. This situation has been overcome in the ball spherometer.
