Lenses Biconvex Glass
Product Code : JA-LOE-7891
The Lenses Biconvex Glass (SKU JA-LOE-7891) are double convex spherical lenses made from optically worked glass, with ground edges and highly polished faces, for converging-lens experiments in school and college physics laboratories. The biconvex glass lens range is listed in two diameters, 38 mm and 50 mm, and seven focal lengths from 50 mm to 500 mm in each diameter, covering short-focus magnifier work as well as long-focus bench set-ups. JaincoLab manufactures the lenses in India for laboratories and education supply programmes.
Specifications
Each lens is a double convex spherical lens in optically worked, polished glass with ground edges, available at 38 mm or 50 mm diameter with a focal length of 50, 100, 150, 200, 250, 300 or 500 mm.

Applications of biconvex glass lenses in optics practicals
Biconvex lenses are the converging lenses at the centre of school and college ray optics, used to form real images on a screen, to find focal length by several methods and to build simple optical instruments on the bench.
- Finding focal length by the distant-object method and by plotting u against v
- Forming real, inverted images of a candle or illuminated object on a screen
- Using short-focus lenses as simple magnifiers
- Building a model telescope or compound microscope from two lenses
- Serving as the auxiliary lens when a concave lens is measured
Scope of supply
Lenses are quoted individually by diameter and focal length, so a laboratory can combine several focal lengths in one order. Accessories, spares and quantities are confirmed on the quotation.
Packing, MOQ and lead time
Lead time, packing and MOQ are set out on the quotation according to the lens sizes, quantities and delivery destination. JaincoLab supplies school orders, class sets for colleges and bulk or export quantities for education projects in Africa, the Middle East and South and South-East Asia.
Frequently asked questions
Which diameters and focal lengths can be ordered?
Two diameters, 38 mm and 50 mm, each in focal lengths of 50, 100, 150, 200, 250, 300 and 500 mm.
What material and finish do the lenses have?
They are optically worked glass with ground edges and highly polished surfaces.
Which focal length suits a school focal-length practical?
Medium focal lengths such as 100 mm to 200 mm are convenient on a bench or metre rule; the choice depends on the bench length and the experiment.
What should a quotation request include?
Send the SKU JA-LOE-7891, the diameter and focal length of each lens, the quantities and the delivery destination.
