BK7 convex lens Dimmesion:+/-0.02 to +/-0.1 surface quality:10/5 to 60/40 Precision:1/4@633nm best and tracking service
Product description
Convex lenses are thicker at the middle. Rays of light that pass through the lens are brought closer together (they converge).
A convex lens is a converging lens.When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
The distance between the principal focus and the centre of the lens is called the focal length.
