Concave Lens

Product Code : SCL-LAO-11885

Indian Lab Suppliers supplies the Concave Lens (Product ID: 11885) as part of its light and optics range. It is a 50 mm double-concave glass lens with the same curvature on both faces.

Quick Answer

A concave lens is diverging: it has a negative focal length and, for a real object, always forms a virtual, upright and diminished image. In the lab its focal length is usually found by pairing it with a convex lens of shorter focal length and measuring the combination. Two grades are offered: a regular school grade with ±10% tolerance on focal length, and an accurate grade made to its stated focal length. Please confirm the focal lengths you need at quotation. Handle with care; glass edges can chip.

Frequently Asked Questions

Is the focal length of a concave lens positive?
No, it is negative because the lens spreads light out.

What diameter is it?
50 mm.

How do the two grades differ?
The regular grade has ±10% focal length tolerance; the accurate grade is made to its stated value.
