UV fused silica cylindrical lenses

What are you looking for in Stock?

Fused silica cylindrical lenses are widely used in the ultraviolet applications and these cylindrical lenses find many applications for beam handling in this spectral region. Like all cylindrical lenses they will create line focii.

These cylindrical lenses are the ultra-violet type manufactured from UV grade fused which is useful a useful choice of material for applications at 185nm and is available in planoconvex and planoconcave forms. We can supply custom UV grade cylindrical lenses in rectangular or circular shaped apertures. We also offer mounting options for seamless integration into your optical system.

Our cylindrical lenses are available in AR coated (248-400nm) and uncoated options. Uncoated cylindrical lenses can be custom AR coated to suite your specific application or edged to circular apertures at short notice.

We can also offer custom UV grade fused silica cylindrical lenses in a range of alternative UV materials such as quartz or calcium fluoride to meet your specific requirements. Alternatively stock rectangular shaped UV cylindrical lenses can be edged to circular apertures at short notice, please enquire.

Please note we also stock BK7 or equivalent Cylindrical lenses for visible/ NIR applications, they are also stocked BBAR coated for 450-900nm.
