 Custom Cylindrical Lenses
Cylindrical Lenses are used to focus or diverge light in single plane only. We offer round and rectangular lenses from stock and both are easy to mount. We stock cylindrical lenses in BK7 and UV Grade Fused Silica for use down to 170nm. Fused silica is best used for hostile environments requiring greater thermal, chemical and radiation resistance. Cylindrical lenses are stocked uncoated or with a multilayer AR coating, a broadband 450-900nm coating on BK7 grade or a 248-400nm on the fused silica range. All uncoated and AR coated cylindrical lenses can be edged to smaller diameters at short notice.
Knight Optical can offer Custom Cylindrical Lenses in a full range of materials from UV through to infrared wavelengths. Whether you have a prototype application or a production run requirement to your unique specification, we are able to accommodate these needs.
