Knight Optical's BK7 stock and custom biconvex lenses

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.
