Product Code : SCL-LAO-14616
Indian Lab Suppliers supplies the Spherometer (Product ID: 14616) as part of its light and optics range. It is a three-legged micrometer instrument for measuring the radius of curvature of lenses and other curved surfaces.
Quick Answer
The three fixed legs stand at the corners of an equilateral triangle, and a central micrometer screw with a 0.5 mm pitch and circular scale measures the small height h of the curved surface relative to the plane of the legs. With l the mean distance between the legs, the radius of curvature is R = l²/6h + h/2. Readings are zeroed on a flat glass plate. The body is brass or aluminium alloy with a chrome-plated finish, and the leg circle is 30–50 mm across depending on design. Least count is 0.01 mm as standard; a 0.001 mm model is also listed, so please confirm least count at quotation.
