Lenses Biconcave Glass
Product Code : JA-LOE-7887
The Lenses Biconcave Glass (SKU JA-LOE-7887) are double concave spherical lenses of optically worked glass with ground edges and polished surfaces, for ray optics and focal-length experiments in school and college laboratories. This biconcave glass lens range is listed in 38 mm and 50 mm diameters, each with focal lengths of 50, 100, 150, 200, 250, 300 and 500 mm, so a laboratory can order matched sets for bench work. JaincoLab manufactures them in India for physics laboratories and education supply programmes.

Applications of the biconcave glass lens in optics practicals
Biconcave lenses are used wherever students study diverging lenses: they form virtual, upright and diminished images, and their focal length is usually found in combination with a convex lens of known focal length on the optical bench.
- Finding the focal length of a concave lens with an auxiliary convex lens, as in senior-secondary practicals
- Showing the divergence of parallel rays from a ray box
- Demonstrating the correction of short sight in lessons on the eye
- Lens-combination experiments to check the power of combined lenses
- Undergraduate optics practicals that need a range of focal lengths
Scope of supply
Each unit is one biconcave glass lens of the diameter and focal length ordered; lenses are quoted per size so that mixed sets can be made up. Accessories, spares and quantities are confirmed on the quotation.
Packing, MOQ and lead time
Minimum order quantity, lead time and packing are confirmed on each quotation according to the sizes, quantities and delivery destination. JaincoLab supplies single schools as well as bulk requirements for colleges, education projects and export buyers in Africa, the Middle East and South and South-East Asia.
Frequently asked questions
Which diameters and focal lengths are available?
The lenses are listed in 38 mm and 50 mm diameters, each with focal lengths of 50, 100, 150, 200, 250, 300 and 500 mm.
What are the lenses made of?
They are double concave spherical lenses of optically worked glass, with ground edges and polished surfaces.
How is the focal length of a concave lens measured in class?
Because a concave lens forms a virtual image, it is usually combined with a convex lens of known focal length on an optical bench and its focal length is calculated from the combination.
What should a quotation request include?
Send the SKU JA-LOE-7887, the diameter and focal length of each lens, the quantities and the delivery destination.
