  • These lenses are also available with a -A, -B, or -C antireflection coating.
  • Much like surface flatness for flat optics, surface power is a measure of the deviation between the surface of the curved optic and a calibrated reference gauge, typically for a 633 nm source, unless otherwise stated. This specification is also commonly referred to as surface fit.

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. To minimize the introduction of spherical aberrations, collimated light should be incident on the curved surface when focusing it to a line, and light from a line source should be incident on the plano surface when collimating.

These N-BK7 Plano-Convex Cylindrical lenses are available uncoated or with one of three Antireflection Coatings, which can reduce the amount of light reflected from each surface of the lens. The uncoated lenses are highlighted on this page. Lenses with a -A (350 - 700 nm range), -B (650 - 1050 nm range), or -C (1050 - 1700 nm range) antireflection coating are featured elsewhere. Please see the Graphs tab for coating information.

For cage system and lens tube compatibility, please see our Mounted Plano-Convex Round Cylindrical lenses. These lenses are typically easier to integrate into our standard optomechanics.

All cylindrical lenses can be ordered uncoated and the cylindrical lenses made from N-BK7 can be ordered with one of the following broadband AR coatings:
-A: 350-700 nm, -B: 650-1050 nm, or -C: 1050-1700 nm

These high-performance multilayer AR coatings have an average reflectance of less than 0.5% (per surface) across the specified wavelength ranges. The central peak in each curve is less than 0.25%. These coatings provide good performance for angles of incidence (AOI) between 0° and 30° (0.5 NA). For optics intended to be used at large angles, consider using a custom coating optimized at a 45° angle of incidence; this custom coating is effective from 25° to 52°. The plot shown below indicates the performance of the standard coatings in this family as a function of wavelength.

Comparison of Circularization Techniques for Elliptical Beams

Edge-emitting laser diodes emit elliptical beams as a consequence of the rectangular cross sections of their emission apertures. The component of the beam corresponding to the narrower dimension of the aperture has a greater divergence angle than the orthogonal beam component. As one component diverges more rapidly than the other, the beam shape is elliptical rather than circular. 

Elliptical beam shapes can be undesirable, as the spot size of the focused beam is larger than if the beam were circular, and larger spot sizes have lower irradiances (power per area). Several different techniques can be used to circularize an elliptical beam, and we experimented with and compared the performance of three methods based on a pair of cylindrical lenses, an anamorphic prism pair, and a spatial filter. The characteristics of the circularized beams were evaluated by performing M2 measurements, wavefront measurements, and measuring the transmitted power. 

While we demonstrated that each circularization technique improves the circularity of the elliptical input beam, we showed that each technique provides a different balance of circularization, beam quality, and transmitted power. Our results, which are documented in this Lab Fact, indicate that an application's specific requirements will determine which is the best circularization technique to choose.

Experimental Design and Setup

The experimental setup is shown in the picture at the top-right. The elliptically-shaped, collimated beam of a temperature-stabilized 670 nm laser diode was input to each of our circularization systems. Collimation results in a low-divergence beam, but it does not affect the beam shape.

The beam circularization systems, shown to the right, were placed, one at a time, in the vacant spot in the setup highlighted by the yellow rectangle. With this arrangement, it was possible to use the same experimental conditions when evaluating each circularization technique, which allowed the performance of each to be directly compared with the others. Some information describing selection and configuration procedures for several components used in this experimental work can be accessed by clicking the following hyperlinks: 

The characteristics of the beams output by the different circularization systems were evaluated by making measurements using a power meter, a wavefront sensor, and an M2 system. In the image of the experimental setup, all of these systems are shown on the right side of the table for illustrative purposes; they were used one at a time. The power meter was used to determine how much the beam circularization system attenuated the intensity of the input laser beam. The wavefront sensor provided a way to measure the abberations of the output beam. The M2 system measurement describes the resemblence of the output beam to a Gaussian beam. Ideally, the circularization systems would not attenuate or abberate the laser beam, and they would output a perfectly Gaussian beam. 

Edge-emitting laser diodes also emit astigmatic beams, and it can be desirable to force the displaced focal points of the orthogonal beam components to overlap. Of the three circularization techniques investigated in this work, only the cylindrical lens pair can also compensate for astigmatism. The displacement between the focal spots of the orthogonal beam components were measured for each circularization technique. In the case of the cylindrical lens pair, their configuration was tuned to minimize the astigmatism in the laser beam. The astigmatism was reported as a normalized quantity.

Experimental Results

The experimental results are summarized in the following table, in which the green cells identify the best result in each category. Each circularization approach has its benefits. The best circularization technique for an application is determined by the system’s requirements for beam quality, transmitted optical power, and setup constraints. 

Spatial filtering significantly improved the circularity and quality of the beam, but the beam had low transmitted power. The cylindrical lens pair provided a well-circularized beam and balanced circularization and beam quality with transmitted power. In addition, the cylindrical lens pair compensated for much of the beam's astigmatism. The circularity of the beam provided by the anamorphic prism pair compared well to that of the cylindrical lens pair. The beam output from the prisms had better M2 values and less wavefront error than the cylindrical lenses, but the transmitted power was lower.

  • Circularity=dminor/dmajor, where dminor and dmajor are minor and major diameters of fitted ellipse (1/e intensity) and Circularity = 1 indicates a perfectly circular beam.
  • Normalized astigmatism is the difference in the waist positions of the two orthogonal components of the beam, divided by the Raleigh length of the beam component with the smaller waist.

Components used in each circularization system were chosen to allow the same experimental setup be used for all experiments. This had the desired effect of allowing the results of all circularization techniques to be directly compared; however, optimizing the setup for a circularization technique could have improved its performance. The mounts used for the collimating lens and the anamorphic prism pair enabled easy manipulation and integration into this experimental system. It is possible that using smaller mounts would improve results by allowing the members of each pair to be more precisely positioned with respect to one another. In addition, using made-to-order cylindrical lenses with customized focal lengths may have improved the results of the cylindrical lens pair circularization system. All results may have been affected by the use of the beam profiler software algorithm to determine the beam radii used in the circularity calculation.

Hello! Is there a damage threshold for the lenses? I have a LJ1695L1 that I'm planning to use with a pulsed laser, 532 nm, 120mJ, 10ns. Thank you!
pbui  (posted 2013-11-14 03:31:34.0)
Response from Phong at Thorlabs: We do not test our uncoated lenses due to their high damage threshold. As long as the uncoated BK7 lens is free from surface contaminants/defects, I would not anticipate any damage from your laser.

Response from Tim at Thorlabs: Thank you for contacting us. We have a few close cases, LJ1874L1 and LJ4107, but no true hemicylindrical prism as a stock option. We will contact you to discuss your requirements to determine possible solutions.

Hi, do you provide hemicylindrical prisms (radius equals to center thickness)?

A response from Adam at Thorlabs: At the design wavelength of 587.6nm, the back focal length of this lens is 22.55mm. I will also send you an email incase you need the back focal length at a different wavelength.

Dear Thorlabs team, Im in need of the backfocal length of the LJ1810L1 (distance between the flat surface of the lense to the back side focal point)! Best regards, Klaus Pelikan
Tyler  (posted 2008-04-09 16:48:10.0)
The front and back focal lengths are not a quantity that we currently have tabulated for our lenses; however, using Zemax the FFL and BFL were calculated for the LJ1878L1 at a wavelength of 587.6 nm. BFL=6.127 mm (measured from the flat surface of the lens to the back side focal point) and FFL=8.5 mm (measured from the apex of the curved surface of the lens to the front side focal point) If you need this information for a small number of lenses we can provide it relatively quickly. I will add this to the list of specifications that customers would like to have for the cylindrical lenses, but it typically takes a fair amount of time to generate a new specification for a large number of products. Thank you for telling Thorlabs of your need. We always appreciate the feedback since it allows us to improve our service to you and future customers.

Hi, It would be helpful for me, and perhaps others, if you would include the back focal length (f_b) with your plano-convex cylindrical lenses, for example the LJ1878L1. The schematic drawing on page 730 (catalog 19) shows this quantity, but the tables on pages 730-733 and beyond do not have this data, although there would be plenty of room for an extra column. It would be great if you could include this in the future, and also on your web catalog. Thanks, Benno Petrig
