Biconvex Lens Synthetic Fused Silica 20mm Diameter 80.6mm Focal Length
SLSQ-20B-80P
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; synthetic fused silica for wavelengths less than 350nm ultraviolet light.
◦Our lenses are listed by outside diameter and focal length to assist your selection according to required specifications.
