Features of Large-Diameter Aspheric Lenses

  • Precision-Polished for Exceptional Performance
  • Large Diameters from 10 - 100 mm
  • Numerical Apertures from 0.23 - 0.619
  • Diffraction-Limited Performance
  • Low Dispersion Materials Minimize Chromatic Aberration
  • Superior Energy Beam Distribution
  • Corrected Wavefront Transmission: 20X to 50X Improvement Over Large-Diameter Molded Glass Aspheric Lenses

Thorlabs stocks precision-ground, large-diameter aspheric lenses from Asphericon. With diameters ranging from 10 mm to 100 mm, these aspheres are available with numerical apertures (NA) ranging from either 0.23 - 0.24 or 0.488 - 0.619. These aspheric lenses are manufactured using CNC grinding and polishing machines; for diameters in excess of 15 mm this produces lenses with RMS wavefront errors that are typically 20 to 50 times less than a similarly sized molded aspheric lens. The lenses are constructed using S-LAH64 or N-BK7 optical glass. Ohara's S-LAH64 optical glass is a low-dispersion glass with high index of refraction in order to minimize chromatic aberration.

For best performance, the curved surface of the lens should face the collimated source for focusing applications. Conversely, when used for collimating a source, the plano surface should face the source.

Do these lenses obey the Abbe sine condition, so that the principal surface is hemispherical and parallel rays from below the lens are brought together in the rear focal plane?

Posted Date: 2013-05-15 11:04:00.0
Response from Tim at Thorlabs: Thank you for your inquiry. These lenses will not obey the Abbe sine condition and a more suitable option in this regard would be a multi element plan objective. We provide Zemax files in the supporting documentation if you would like to quantify the performance. I will contact you with simulated data on this.

Response from Sean at Thorlabs to akde: In response to your numerical aperture measurement, please note that the definition of NA is n_air*sin(theta), where theta is the angle between the marginal ray and the chief ray in image space. Note that it is the index of the medium surrounding the lens (typically air), not the index of the lens itself, that is used in the definition of NA. Also note that the NA for these lenses is defined at the design wavelength of 780 nm, and for a perfectly collimated input beam of Ø46 mm (the clear aperture of the lens). If this is not the case, then you will measure an angle that is different than 30° which yields the defined NA. Also, the NA specified on our website for the AL5040 is incorrect, it is actually 0.50. We will get this corrected throughout our documentation soon. Thanks again for the good discussion and your feedback.

Response from Sean at Thorlabs: Thank you for your additional feedback clarifying the source of your confusion. I will update the diagram on our aspheric condenser lenses and add one to our large diameter aspheric lenses pages today with additional information on the principal plane. In addition, I will also look at all of our lens pages to ensure that the definition of the effective focal length and the principal plane is clear. Since the principal plane location will vary from lens to lens (and for some lens designs, will even be outside of the physical lens), it is probably not practical to put this information on the AutoCAD PDF drawings. We are checking into the NA defined for these lenses and I will post a complete reply for that question as soon as more information is available.

Response to Sean: (Continuing with my earlier feed-back on NA values of ACLs and ALs): It turns out that the NA values reported are found to be in excellent agreement if NA is defined as only the sine of the half-angle of focusing. Multiplying by refractive index (a number larger than 1) makes the NA values higher than reported values. Thus an NA of 0.619 (for AL7560) reported on the website is indeed an NA of ~0.935.

Response to Sean: Thank you very much for your reply. (1) It will be nice if the location of the principal plane is shown in the Auto CAD drawing. The confusion was because I was following the figure for aspheric condenser lenses (ACLs) for which the EFL turns out to be very close to the "working distance" or "back focal distance" (distance of the focus from the flat surface) plus the "edge thickness". (2) I measured the half-angle of focusing for few large-diameter aspheric lenses (ALs); for example, for AL5040 the half-angle turns out to be close to 32 degrees which yields (taking refractive index 1.5) a NA of ~0.8, much higher than the reported value (0.554)!

Response from Sean at Thorlabs: Thank you for your feedback on our large diameter aspheres. The effective focal lengths listed on our specs table are correct. The 2.4 mm measurement you cite for the AL2520 is simply the edge thickness of the lens, and does not indicate the location of the principal plane. We designated the 0.488 – 0.619 range of numerical apertures as “high” because these are higher than usual for a singlet lens. The aspheric profile of these lenses allows NAs that are greater than what are possible with spherical profiles. However, in the paragraph text of the overview tab, I have added the range of “low” and “high” NAs to ensure that this distinction is clear.

Posted Date: 2012-04-17 23:41:06.0
The effective focal lengths (EFLs) of these lenses are somewhat confusing! for example, the EFL of AL2520 is not 20mm (following the specification) but turns out to be (following the autocad drawing) 2.4mm + 15.7mm = 18.1mm. Also, the "high NA" values are bit misleading. An NA of 0.6 produces a shallow focus with half angle of only ~25 degrees and cannot be considered as "high NA". Usually (in microscopy literature) "high NA" corresponds to NA = 1.0 or more so that the half angle is at least ~45 degrees or more. Dr Arijit K De (LBNL/UCB, Berkeley)

Response from Javier at Thorlabs to last poster. Thank you very much for your feedback. The A2 term is not used in Code V and other applications since the K constant has the same control in the aspheric lens equation. Please contact us at techsupport@thorlabs.com and we will gladly provide information for any particular lens(es) you may be interested in.

You represent the asphere profile with a a2 term. In code V, there is no modeling of an a2 term for an asphere profile (goes from K constant, a4, a6, a8, etc...) similar to the profile you show on your molded asphere lenses. Can you please clarify what the a2 coefficiency corresponds to or put a format that matches normal asphere approaches?

Response from Javier at Thorlabs to spotnis: Thank you very much for submitting your request. We modeled the output profile of the AL2550-A lens in Zemax and did not find any changes in the performance, other than the inherent focal length shift of the lens (at 405 nm, the back focal length of the lens is 44.288 mm). Also, N-BK7 transmits well at 405 nm (~99%), so the rings and artifacts are most likely due to other factors affecting your setup. I will contact you directly to troubleshoot your application a bit further.

I have tried using AL2550-A (f=50mm) for collimation of the output of a fiber. The wavelength is 405nm. The collimated beam does not have a gaussian profile, in fact it has a lot of rings and artifacts. The output of the fiber when collimated using an achromatic doublet of similar focal length (AC254-045-A) has a good gaussian profile. What is the performance of these aspheres for wavelengths other then the design wavelength 780 nm?

Response from Buki at Thorlabs: Thank you for your feedback. You are correct about the mistake in the wavefront error under the specs tab. These aspheres (designed at 780nm) have different WFE that vary from one lens to another. To determine the individual spec sheets and drawings for these lenses, please click on the document icon beside the lens part number. We will soon update the information on the web to accurately display the specifications of these large diameter aspheres. Please contact TechSupport@thorlabs.com if you have further questions.

please be sure that the specification is not surface accuracy. 0.2 micron RMS surface accuracy is about 0.07 micron RMS WFE if you have an index of 1.5

the overview describes these lenses as diffraction limited performance your specs are 0.2 to 0.35 micron typical and 0.5 micron maximum RMS WFE. diffraction limited for 1 µm light is 0.07 micron RMS WFE. Sounds like you are at best 3x diffraction limit.
