Scientifc Equipment Spherometer is a precision educational measuring instrument designed for determining the radius of curvature of spherical surfaces such as lenses, mirrors, curved glass plates, and optical components. It is suitable for school science laboratories, college physics labs, optics practicals, engineering labs, STEM classrooms, and teacher-led demonstrations.

The spherometer helps students understand accurate measurement of curved surfaces using a central screw and three supporting legs. It is commonly used in physics experiments to measure the curvature of convex and concave surfaces and to calculate the radius of curvature using standard laboratory methods.

Product Description

The Spherometer by Scientifc Equipment is a practical physics laboratory apparatus used for measuring small height differences and determining the curvature of spherical surfaces. It generally consists of a circular or triangular metal frame with three fixed legs, a central micrometer screw, a graduated circular disc, vertical scale, and pointed contact tips as per supplied model configuration.

During an experiment, the three fixed legs rest on the surface being measured while the central screw is adjusted until it touches the surface. By comparing readings on a plane surface and a curved surface, students can calculate the sagitta and radius of curvature. This makes the instrument useful for teaching measurement accuracy, screw gauge principle, curvature, optics, and practical physics calculations.

Scientifc Equipment Spherometer is ideal for physics laboratories, optics experiments, lens testing, mirror surface study, engineering measurement practice, and STEM-based practical learning.
