A Biconvex Lens, or a Double Convex Lens, is an optical lens having two spherical sides with identical radii of curvature that focuses light toward a single point. N-bK7 is an excellent optical grade glass material prevalent for uses in the visible and NIR spectrum. Shalom EO offers Stocked N-BK7 Biconvex Lenses
