These are just two possible configurations of many available. All the low order dual wavelength waveplates are mounted in a Ø25.4 mm black anodized aluminum ring and feature a clear aperture of 18 mm. Controls polarization for dual-wavelength sources.

Dual-wavelength low-order waveplates are made from high-quality crystalline quartz and are available at quarter-wave, half-wave, and full-wave retardance.

Waveplates are made from materials that exhibit birefringence. The velocities of extraordinary and ordinary rays through the birefringent material vary inversely with their refractive indices. Differences in velocity give rise to a phase difference when two beams recombine. At any specific wavelength, this difference is governed by the thickness of the retarder (waveplate).

Cylindrical lenses are less common than spherical lenses, but are still wide spread in many Photonics applications, below you’ll find a complete guide to let you learn more about it:

The focal length of a lens is a number, measured in millimeters, which determines how wide angle or telephoto a lens is. A diagram showing different subjects ...

To guaranty a good surface aspect, polishing cylindrical lens use specific polishing toolings and polishing pads. See above an example of such a tool, you’ll notice that for cost saving, several cylindrical glass lenses are polish at the same time.

Cylinder lensvs cylindricallens

Whereas a spherical lens is perfectly symmetric along a central rotational axis, it is not the case for the cylindrical ones.  Which means while the rotation angle by which the lens is used has no impact for the first one but will impact the optical system for the former one. Assembly of cylindrical lenses are therefore subject to one more constraint.

The main difference stands in the way the light rays are deviated through it. Spherical lens tends to focus on a point whereas cylindrical ones focus on a one dimension line.

A cylindrical lens is a lens with at least one optical surface has the shape of a section of a cylinder. While spherical lenses surfaces are defined from a fix center of curvature and a radius, cylinder lens shape are made along a central axis with a fix radius of curvature.
