Data sheet Biconcave Lens D25.4mm 400 - 700nm
Description
Symmetrical biconvex lenses are most useful when dealing with finite conjugate points. This makes them ideal for 1:1 imaging applications or for use in multi-element systems.
There are two types of biconvex lenses available; BK7 for use in visible range to infrared wavelength range.
Our lenses are listed by outside diameter and focal length to assist your selection according to required specifications.
