Lenses Biconcave & Convex
Product Code : JA-LOE-7889
The Lenses Biconcave & Convex (SKU JA-LOE-7889) listing covers 50 mm diameter biconcave and biconvex lenses in 100 mm and 150 mm focal lengths, for comparing converging and diverging lenses in school and college optics practicals. Because the 50 mm biconvex and biconcave lenses share the same diameter and focal lengths, students can pair them to study lens combinations and image formation directly. JaincoLab manufactures them in India for physics laboratories and education supply programmes.
Specifications
The listing covers four lenses of 50 mm diameter: biconcave with a 100 mm or 150 mm focal length, and biconvex with a 100 mm or 150 mm focal length.

Applications of the 50 mm biconvex and biconcave lenses
The paired lenses are used to compare converging and diverging behaviour and to find focal lengths on the optical bench, including the standard method of measuring a concave lens in combination with a convex lens.
- Finding the focal length of a convex lens by the u-v method
- Finding the focal length of a concave lens with a convex lens of known focal length
- Showing that equal and opposite lenses in contact give almost no net power
- Converging and diverging ray demonstrations with a ray box
- Simple telescope and lens-combination experiments on the bench
Scope of supply
Each lens is quoted by type and focal length (biconcave or biconvex, 100 mm or 150 mm), all at 50 mm diameter. Accessories, spares and quantities are confirmed on the quotation.
Packing, MOQ and lead time
The quotation confirms minimum order quantity, packing and lead time for the lens types, quantities and delivery destination. JaincoLab supplies small school orders and bulk quantities for colleges, education programmes and export buyers in Africa, the Middle East and South and South-East Asia.
