Double Disk Spherometer

A double disk spherometer is a precise instrument designed to measure the radius of curvature of curved surfaces, particularly useful in optical applications for measuring lens curvature. Traditionally employed by opticians, this tool features a double disc made of brass, coated with nickel to resist rust. The spherometer is equipped with three pricking legs that ensure accurate readings, making it an invaluable asset for both students and teachers in educational settings, such as classrooms and laboratories. Its ability to provide meticulous measurements of spherical and curved surfaces positions the spherometer as an essential device for anyone engaged in the fields of engineering, physics, or optics. With its straightforward design and practical applications, the spherometer remains a cornerstone in the study and measurement of curvature.
