Biconvex lenses are a good quality simple form of lens; typically both faces are convex and spherical. UV grade fused silica biconvex lenses are widely used for moderate quality imaging and also for focussing and control of laser beams in UV applications. Generally biconvex lenses have the same radius of curvature on both spherical surfaces.
Our stock range of quality grade UV Grade Fused Silica lenses are available uncoated or AR coated for ultra-violet applications from 248-400nm although the lens can work down at 185nm through to NIR applications at 2000nm. Knight optical also offers custom biconvex lenses to meet your requirements or alternatively edge stock lenses for a quick turnaround.
Stock lenses can be edged to smaller diameters.
Stock lenses can be ground to rectangular and square shaped apertures.
