UV-fused silica cylindrical lenses - Quality grade (Uncoated) Cylindrical Lenses focus or diverge light in one plane only. Our circular lenses are particularly convenient for mounting; the longer-focus lenses are simply cut to a circular shape, whilst the stronger lenses are mounted in a recess on a black anodised aluminium disc. B270 optical crown lenses are offered for the visible and near IR, and fused silica for the UV; both are also available multiplayer AR coated to improve transmittance.
