Features

  • Cylindrical Lenses Featuring an Aberration-Reducing Acylindrical Surface
  • Numerical Apertures Ranging from 0.45 to 0.54
  • Available with Either a 350 - 700 nm or 650 - 1050 nm AR Coating

These acylindrical lenses are the cylindrical counterpart to an aspheric lens; they are designed to combine the aberration-reducing benefits of an aspheric surface with the one-dimensional focusing of a standard cylindrical lens. The lenses sold on this page are manufactured using a computer numerical controlled (CNC) grinding and polishing process.

Positive cylindrical lenses are ideal for applications requiring magnification in one dimension. While spherical lenses act symmetrically in two dimensions on an incident ray, cylindrical lenses act in the same manner but only in one dimension. A typical application is to use a pair of cylindrical lenses to provide anamorphic shaping of a beam. A pair of positive cylindrical lenses can be used to collimate and circularize the output of a laser diode. Another application possibility would be to use a single lens to focus a diverging beam onto a detector array.

These cylindrical lenses are slightly deviated from a true cylinder in a way that minimizes the introduction of aberrations, which yields a wavefront error of 500 nm (RMS). The lenses are manufactured using S-LAH64 optical glass, which is a low-dispersion glass with high index of refraction in order to minimize chromatic aberration.

Please see the Selection Guide table to the right for our full selection of precision aspheric lenses.

Mounting Options
These lenses may be mounted in one of our cylindrical lens mounts. For a specific mount recommendation for each lens, please see the Mounting Options tab.

Dear Thorlabs, I wonder if your company can help us cut this lens into a 1 inch round version just like LJ1695RM. Thanks Best, Allen

Dear Sir, We are interested in the acquisition of an 8.0 focal length acylinder from your company. The element of interest is the AYL108. Due to the special application of the system we would like to know if it is possible to acquire such product with two special features: 1- We would require the lens to be uncoated. Is that a possibility? 2- The dimensions of the component is 10mmx10mm. We are currently interested in a longer lens. In fact we would like to have a 25mmx10mm or even longer. Is it possible to have such component? Thank you very much and best regards, Daniel Perez Calero Optical designer TNO
