As the name suggests, cylindrical lenses are either round or rectangular objects with cylindrically shaped surfaces. They differ from spherical lenses in that they focus a beam to a focal line rather than a focal point.
Transmission is improved by applying an anti-reflection coating on both sides, and multilayer coatings are available for various areas of the light spectrum. Cylindrical lenses can be made from ZnSe, Ge, Si, and other IR materials.
Applications include laser scanners, laser diode systems, spectrophotometers, projectors, and optical data storage and retrieval systems.

We offer a selection of very precise cylindrical lenses, both positive and negative, in glass and fused silica. These lenses are well suited for applications which require magnification in one dimension only. Examples include energy collection for linear detectors or for coupling to a slit input, source generation for barcode scanners, circularization of diode laser outputs, one-dimensional image compression, and other similar applications.
Cylindrical lenses are more difficult to manufacture than spherical lenses but we take great care to ensure that the lens power is confined to a single axis and that the lenses are tightly specified so that you can use them with confidence in a complex imaging system.The lenses we offer here represent some of the more general requirements of our customers. But please call if you need a different shape or size. The lenses are uncoated but our standard coatings may be applied by choice of the appropriate coating suffix.

These patented gradient-index cylindrical microlenses with Luneburg type refractive index distribution are drawn from a highly polished gradient-index fiber preform. A simple tuning of the drawing process produces diffraction-limited microlenses in the shape of fibers or rods with precise diameters and unsurpassed surface quality. When illuminated sideways, these fibers act as perfect cylindrical lenses with 0.5 NA. The fused silica cladding and the gradient-index core of these lenses withstand very high temperatures (transition temperature is ≈1100°C). The lenses can be used in visible and near infra red spectrum.
The rods or fibers are cut to desired length. The round cross-section of these lenses results in the large field of view and simple, cost-effective alignment with the laser diodes where most of the positioning errors result in simple focusing errors. This leads to effective "best focus" search beneficial for automated or manual positioning.
These lenses could be used either as fast-axis collimators for single laser diodes or for building cylindrical lens arrays for laser diode bars. In order to accommodate a small emitter pitch, the edge of the lens may be ground to a desired width.

Meniscus cylindrical lenses act just like meniscus lenses, but in one dimension. These large radius cylindrical lenses are made out of optical quality glass.

|
These large radius cylindrical lenses are made by grinding and polishing of optical quality glass.

These large radius cylindrical lenses are similar to cut-rod lenses except that their dimensions are larger and the fabrication process is different.

A cylinder is a surface that is circular in one direction and flat in the orthogonal direction. A cylindrical optic has one or more cylindrical surfaces. Cylindrical optics are used in medical instruments, graphic arts, laser printers, and semiconductor processing equipment.
Optimax uses several interferometric techniques including plano reference flats, spherical transmission lenses, and diffractive optical elements to verify the plano axis and power axis of the optic.
Optimax inspects 100% of all optics and provides test data with prototype orders. We utilize state-of-the-art metrology and provide on-time delivery guarantees to ensure your satisfaction!
Optimax can provide optics complete with BBAR, V-coat, and mirror coatings. We have four electron-beam coaters supported by a Perkin-Elmer Lambda 900 Spectrophotometer. For more details please see our Coatings data sheet.
