A Biconvex Lens, or a Double Convex Lens, is an optical lens having two spherical sides with identical radii of curvature that focuses light towards a single point. UV Fused Silica is the amorphous form of Silicon Dioxide with the superior transmission in the UV region and could be utilized for wavelengths ranging from Ultraviolet (UV) to Near-infrared (NIR) spectrum. Shalom EO offers Stocked UV Fused Silica Biconvex Lenses.
