SPHEROMETER Meaning and
Definition
-
A spherometer is a precision measuring instrument that is primarily used in metrology to measure the curvature or radius of a spherical surface. It consists of a central circular plate with three or more screw-like legs that are equidistantly positioned along the perimeter of the plate. The legs have finely threaded ends that allow for small vertical adjustments.
To measure the curvature of a spherical object, the spherometer is placed on the surface, and the screws are gradually adjusted until all three legs make even contact. The height of each leg is then measured to determine the radius of curvature. By taking multiple readings at various points on the surface, the spherometer can provide accurate information regarding the sphere's shape and uniformity.
Spherometers are commonly used in fields such as optics, astronomy, and precision engineering. They are particularly helpful in determining the accuracy and quality of lenses and mirrors, as they provide quantitative data about their surface characteristics. Additionally, spherometers can be used in the calibration of other instruments and in the production of spherical objects.
The design and construction of spherometers have evolved over time to incorporate high-precision mechanics and digital components. Modern variants may include measurement displays, motorized adjustments, and other features to enhance accuracy and ease of use.

Etymology of SPHEROMETER
The word "spherometer" is derived from the combination of two root words: "sphere" and "meter".
1. "Sphere" comes from the Latin word "sphaera" (meaning "globe" or "ball"), which can be traced back to the Greek word "sphaira".
2. "Meter" is derived from the Greek word "metron", which means "measure" or "measurement".
When these two root words are combined, "spherometer" simply means a measuring instrument or device used specifically for measuring spherical objects.
