Spherometer
Product Code : JA-M-7905
The Spherometer (SKU JA-M-7905) is a brass instrument for measuring the radius of curvature of spherical lenses and curved surfaces in school and college physics practicals. It has a vertical scale reading 10-0-10 mm and a micrometre scale with 100 divisions, so students can measure the small height of a curved surface above a flat plane and calculate its radius of curvature. This brass spherometer for radius of curvature work is manufactured in India by JaincoLab.
Specifications
The spherometer is made of brass, with a vertical scale of 10-0-10 mm and a micrometre (circular) scale divided into 100 divisions.

Applications of the brass spherometer
The spherometer measures the sagitta, the small height of a curved surface above the plane of its three legs, from which the radius of curvature is calculated; the experiment appears in senior-secondary and first-year undergraduate practical syllabuses.
- Determining the radius of curvature of a convex or concave lens surface
- Finding the radius of curvature of a spherical mirror or watch glass
- Measuring small thicknesses, such as that of a thin glass plate
- Teaching pitch, least count and zero error of a screw instrument
- Combining with focal-length data to find the refractive index of lens glass
Scope of supply and ordering
Each unit is one brass spherometer with its vertical and micrometre scales. A flat glass plate, accessories, spares and quantities are confirmed on the quotation.
Minimum order quantity, lead time and packing are set out on each quotation according to the number of instruments and the delivery destination. JaincoLab supplies spherometers singly or as class sets to schools and colleges, and in bulk to education projects and export buyers in Africa, the Middle East and South and South-East Asia.
