Cylindrical Optics

There are many challenges inherent in manufacturing cylindrical lenses: mechanical geometries drive process selection and capabilities, for example. Manufacturers must be well-versed in how different manufacturing techniques can influence cylinder specification, and to make design recommendations that will reduce cost and improve tolerances.

At Optimax, customers benefit from a dedicated team of experienced engineers operating with advanced manufacturing processes to deliver solutions, not just products.



Our quotes are structured to offer standard pricing and delivery – quicker delivery options are available upon request.

What are Cylinder Lenses?

Cylindrical optics are a type of lens with a curvature in a single direction, yielding different radii in the X and Y axes. Optical cylinders are subsequently ideal for condensing, focusing, or expanding incoming light. Optimax fabricates cylinders from a range of materials, utilizing a deterministic CNC machining process to ensure predictable removal rates and tight adherence to critical tolerances.

The surface curvature of cylindrical optics is typically spherical and they tend to have a plano-convex or plano-concave design, coming in circular, rectangular, or square profiles. These are used for a broad range of applications across the full spectrum of industry and research. Common uses of cylindrical lenses include correcting astigmatism and altering the shape of laser beams prior to collimation.

OEMs rely on optical cylinders for various purposes in holography, optical spectroscopy, laser line scanning, and more. Those same OEMs depend upon Optimax to overcome critical manufacturing challenges and to routinely deliver the highest quality cylindrical optics.

Specifying Cylinders

Several key parameters must be defined when specifying cylindrical optics, namely a tolerance for the radius – or power – axis and the plano – zero power – axis. Manufacturers must also define decentration in both axes, and the alignment of the optical axis with the mechanical one. Irregularity and slope may also be specified.

Optimax cylinder lenses are verified using interferometric techniques, including distance measuring interferometry, plano reference flats, and CGH diffractive elements. The latter converts the plane wavefront from a transmission flat to a cylindrical wavefront, which can be used to measure both concave and convex surfaces. The available coverage varies greatly based on the size and shape of the cylindrical surface.

For more information on CGH nulls and an illustration of available coverage please see:

Manufacturing Cylindrical Optics

Cylindrical lenses comprise an optical surface that has a radius in one direction and is flat in the orthogonal direction. The manufacturing methods used in cylinder manufacture account for this axis, subsequently conserving position. There are two primary production techniques used to fabricate cylindrical optics – the Arbor process and the X-Y process.

The radius of curvature divided by diameter – or width – gives an R-number, which helps define which technique should be selected. Alternatively, order quantity may be the determining factor in method selection. At Optimax, we pride ourselves on delivering a collaborative service, offering customers the benefit of our extensive expertise and assisting with the burden of choice.
