Biconvex Lens 30mm Diameter 51.1mm Focal Length 400 - 1600 nm
SLB-30B-50PBB
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.
◦This is a BK7 lens with a multi-layer anti-reflection coating for the visible to near-infrared range (400-1600 nm).
◦You can select from a wide variety of options, classified by their outer diameter size and focal length, to meet your specific requirements.
