Custom

What are you looking for in Custom?

We are able to supply custom cylindrical lenses in a range of forms and grades. We offer quality grade cylindrical lenses in materials such as, although not limited to, BK7 or equivalent and UV Fused Silica, and also more commercial standard lenses. We supply cylindrical meniscus lenses, which work just like meniscus lenses, only in one dimension and we can also offer sets of cylindrical lenses, tailored to suit your range of needs.

Our high quality BK7 or equivalent and UV Fused Silica cylindrical lenses can be used to create a round beam from a diode laser’s elliptical output, we will provide these in whichever quality you require, from precision grade to commercial grade. Should you need a comprehensive selection of lenses, with a range of shapes and focal lengths, we provide sets to suit your needs. A meniscus cylindrical lens can turn a transmitted plane wave into a cylindrical wave, and can also correct ocular astigmation.

Knight Optical is able to provide custom cylindrical lenses, cylindrical meniscus lenses and sets thereof for general applications, whilst also offering high precision forms with increased performance and specification for diode laser and all other applications.

Contact our multilingual technical sales team and discover how Knight Optical’s high quality custom cylindrical lenses can improve your product and supply chain experience.
