Knight Optical (UK) Ltd Biconvex Lens BK7 40mmdia x 40mm F.L. AR coated (R<0.5% 450-900nm) LBV4040-AV2

Biconvex lenses are one of the most simple lenses, but good quality, glass lenses with both faces convex and spherical. Biconvex lenses are widely used for moderate quality imaging and also for focussing and control of laser beams. Generally biconvex lenses have both surfaces with the same curvature. Knight Optical's stock range of quality grade N-BK7 or equivalent biconvex lenses are available uncoated or broadband AR coated for visible through to NIR applications. Knight optical also offers custom biconvex lenses to meet your requirements or alternatively edge stock lenses for a quick turnaround. We can supply alternative coatings where requested, including broadband 630-1100nm and 1050-1700nm anti reflective coatings for IR and telecoms applications.
