Biconcave Lens 10mm Diameter −39.7mm Focal Length 633 - 1064nm
SLB-10B-40NIR1
These biconcave lenses are used when a very high negative power is required. They can be used in a multi-element system or alone to produce a diverging cone or virtual image. Sharpe edges, which are common in negative lenses, are removed by beveling to reduce the likelihood of chipping.
◦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.
