Double Convex Lens

Name: Double Convex Lens
Brand: ECOPTIK INDUSTRIAL PTE.LTD.

The double-convex lens is the most basic type of converging lens, with a symmetrical structure suitable for bidirectional optical paths, but its aberration control has limitations. It is suitable for low-precision imaging systems, such as projection toys and simple microscopes.
