  • 球面レンズよりも高いNAを有する非球面コンデンサーレンズ
  • 直径は10~75 mmまでの13種類から選択可能
  • NA:0.52~0.79
  • コーティング無し、350~700 nmまたは650~1050 nm用ARコーティング付きでご用意

照明の高効率化用途に

  • 集光
  • 投影
  • 検出

当社の非球面コンデンサーレンズは、球面レンズに比べて高いNA(低いF値)を有しています。このため、これらのレンズは照明の高効率化用途や、ランプおよびLEDのような光源からの光をコリメートするのに適しています。10~75 mmまでの直径でラインナップしています。コーティング無しは380~2100 nm用、ARコーティング付きは350~700 nm用(-Aコーティング)または650~1050 nm用(-Bコーティング)となります。 -Aコーティングの設計波長は350~700 nmですが、光学クラウンガラスは380 nm以下の波長で吸収を示します。コーティング付きバージョンの反射率に関しては、右のグラフ内のアイコンをクリックいただくとご覧いただけます。

コンデンサーレンズは、球面レンズなどのレンズに比べて焦点距離が短くF値が低いため、レンズ間距離やほかの素子との間隔を小さくできます。よって、ディテクタに光を集光するなどの集光用途に適しています。 レンズの非球面側は高精度な型成形により形成され、平坦面側もしくは球凸面側は研削および研磨により形成されています。適切な性能を得るためには、レンズの平坦面を光源に向けてください。注:B270材料は380~2100 nmの波長を透過しますが、これらのレンズは可視波長域用に設計されています。これ以外の波長における性能は、下記掲載の各レンズの表内にある焦点シフトのグラフをご覧ください。

当社では、このレンズを取り付ける際にスパナレンチ用に隙間を作る、SM05、SM1、SM2ネジ付きの厚型固定リングもご用意しています(詳細は「Lens Mounting Guide」タブをご参照ください)

要求が厳しい用途には、設計波長で回折限界の性能を示す精密CNC研磨非球面レンズ(N-BK7S-LAH64UV溶融石英の各材料でご用意)をお勧めします。当社では、平坦面側が研磨された拡散板になっている非球面コンデンサーレンズもご用意しております。

当社の固定リングはマウント無しの光学素子をレンズチューブまたは光学マウント内に固定します。リングの位置固定には対応するスパナレンチを使用します。平面光学素子や曲率が低い光学素子用には黒アルマイト製の固定リングをØ5 mm~Ø101.6 mm(Ø4インチ)まで標準品としてご用意しております。曲率が高い光学素子用には、厚みのある固定リングをØ12.7 mm(Ø1/2インチ)Ø25.4 mm(Ø1インチ)Ø50.8 mm(Ø2インチ)でご用意しております。

厚みのある固定リングは非球面レンズ、短焦点距離の平凸レンズコンデンサーレンズなど、曲率が高い光学素子の取り付けに使用します。右の動画のように通常の固定リングを曲率が高い光学素子に使用した場合、スパナレンチのガイドフランジが光学素子の表面に接触し、光学素子を傷つける可能性があります。また、スパナレンチと固定リングの間に隙間ができるため、固定リングが正しく締め付けられません。厚みのある固定リングは、スパナレンチが光学素子の表面に接触することなくレンズを固定させることができます。

Like the comment of barney.william, I'm trying to calculate the NA of these lenses, albeit by a different approach, which I believe should be accurate (at least for the plano-aspherical lenses): I take the sag formula: z=z(y), differentiate it by y: tan(alpha)=dz/dy, and then I expect to calculate: NA=sin(alpha). I plugged in the numbers you provide in your product table. Why don't I get the NA you present?
YLohia  (posted 2018-06-26 09:24:37.0)
Hello, thank you for contacting Thorlabs. Is there a particular lens you are looking at that yields a significantly different NA? In general, the equations provided by Tyler (tfrisch) in response to the comment by barney.william you mentioned (NA=D/(2f) or tan(NA)=D/(2f)) are fairly decent approximations. That being said, as Tyler said in his reply, these equations will not give you the most accurate NA due to the thickness of the lens, index of refraction, etc. All of the NAs listed on this page are simulated using the ray tracing software Zemax.

Do you have the item ACL25416U-A with standard metric size (25 mm instead of 25.4 mm)? If not, what is your suggestion for mounting the lens?
nbayconich  (posted 2017-05-18 02:23:49.0)
Thank you for contacting Thorlabs. We recommend mounting our 25mm and Ø1" aspheric lenses in our SM1 threaded lens tubes prior to mounting into one of our SM1 threaded optical mounts. For example the ACL25416U-A can be mounted inside an SM1L05 and then mounted to an LMR1 fixed lens mount using our extra thick SM1RRC retaining rings. A techsupport representative will contact you directly for more information on quoting a Ø25mm version of the ACL25416U-A.
barney.william  (posted 2016-12-08 13:09:24.353)
What is the formula for calculating numerical aperture? I am using sin(atan(CA/2f)) where CA is clear aperture and f is the back focal length. That doesn't seem to give the same values listed on this page. Thanks in advance for the education! Bill
tfrisch  (posted 2016-12-15 01:35:10.0)
Hello, thank you for contacting Thorlabs. The short answer for why the NA does not match the usual models of NA=D/(2f) or tan(NA)=D/(2f) is that these condenser lenses are thick. By default modeling software often uses a paraxial ray trace, but in this case, a real ray trace is required for the most complete description of the NA. I will reach out to you with more details, but if you have access to Zemax, you can set a real ray trace using our provided models.

Response from Bweh at Thorlabs USA: We have not established damage threshold for these yet but have some recommendations depending on your laser characteristics. I will follow-up with you.
user  (posted 2015-07-06 16:53:36.39)
My question is about the back focal length on the ACL25416U (and actually other lenses for which the face other than aspherical is non-plano). I am a bit confused because on the CAD drawing the BFL is noted with "(ref)" and on that same autoCAD pdf, "ref" refers to the edge thickness. So, is the back focal length (noted fb on your reference drawing) taken from the surface S2 (from the auto CAD drawing) or from the intersection of that surface S2 with the edge (edge thickness "te")?
besembeson  (posted 2015-09-22 09:46:44.0)
Response from Bweh at Thorlabs USA: The back focal plane reference will be from the S2 surface. A better reference drawing for this will be here: http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=4847
user  (posted 2014-07-18 11:08:32.2)
Which is the correct BFL of the ACL3026 lens? In the datasheet it is 19.3mm, but in the ZEMAX file it is 22.6mm.
myanakas  (posted 2014-08-07 08:48:37.0)
Response from Mike at Thorlabs: Thank you for your feedback. The back-focal length depends on the wavelength. Also in order to determine the correct value you should apply the “Marginal Ray Height” function. This is an optimization for calculating this distance correctly. You would just have to choose it from the pull down menu in the Thickness column. So instead of “V” for Variable please choose “M”. Then this distance is calculated correctly. It is about 19mm, depending on the wavelength. If you like to change the wavelength you can also do that by going into the “WAV” menu on the upper menu of the Zemax window.
jp  (posted 2014-05-27 10:36:08.48)
Is the focus length of a lens is wavelength dependent? If it is ,how is the relationship between them?
cdaly  (posted 2014-05-29 04:20:50.0)
Response from Chris at Thorlabs: Yes, the focal length is going to be dependent on the wavelength for any lens. For the ACL108, the shift should not be any more than 0.55mm over the full range(380-2100), but I will send you the curve generated from Zemax with more detailed information.

There seems to be an error with the prescription data and .zmx file for ACL3026- its modeled performance seems to be far less than other lenses in this category. Is the prescription data for ACL3026 accurate?
jlow  (posted 2014-03-27 11:44:08.0)
Response from Jeremy at Thorlabs: The prescription is accurate. The ACL line is not a high performance line and are mainly used for less-demanding application. I would recommend our precision CNC-polished aspheres if you require better performance.

Specifications and coefficients for this aspheric lens dont seem consistent according to Zemax. Is the 4th order coefficient for the ACL2520 equal to -1.5e-5, not +1.5e-5? Thanks! John
Thorlabs  (posted 2010-12-01 15:42:32.0)
Response from Javier at Thorlabs to Edgar: I will work with our web team on updating this page with ZEMAX files for the aspheric condenser lenses. In the meantime, I will send you the zmx file for the ACL2520.
edgar.guevara  (posted 2010-11-30 18:09:24.0)
Can you post the full prescription data for ZEMAX, I think it would be very useful for all the users. I am trying to collimate the light from a LED, but I do not know if this aspheric (ACL2520) is enough.
Thorlabs  (posted 2010-10-11 14:06:22.0)
Response from Javier at Thorlabs to saxena.a: We would recommnend using the AL2520-A large diameter aspheric lens for this purpose. This lens, designed for diffraction-limited performance, has a better collection efficiency and better resolution than its ACL counterpart.
Thorlabs  (posted 2010-07-07 08:28:15.0)
Response from Javier at Thorlabs to mrubioroy: thank you for your reply. The easiest way to determine where the principal planes are for this lens is by ray tracing. For this purpose, it is important to know the wavelength(s) that you are working at, since Snells law needs to be applied, and we would need to know the index of refraction of the lens material at the operating wavelength. Also, beam diameter needs to be considered. I will contact you directly to work out all these details.
mrubioroy  (posted 2010-06-09 12:22:40.0)
Response to Javier: I guess my question should be: Can I know where the principal planes are?
Javier  (posted 2010-06-08 04:24:57.0)
Response from Javier at Thorlabs to mrubio: for a thin lens, the effective focal length can be considered as being measured from the center of the lens to the focal point. However, for a thick lens such as the ACL2520, the focal length is measured from one of the pricipal planes, which are basically defined as hypothetical planes were all the refraction is considered to happen. The thin lens equation can be used, but it disregards the distance between these planes. Gullstrands equation takes this distance into account, but the calculation process can get very involved. So, although the answer is not straightforward, you can consider the effective focal length as being measured a few millimiters from the convex surface of the lens. I will contact you directly in case you would like to discuss this further. Regarding your question about back focal length, you are correct; it is measured from the flat, or plano, side.
mrubio  (posted 2010-06-07 16:20:13.0)
From where is the EFL of 20mm on ACL2520 measured? Is the back focal distance measured from the flat side?

Sir, We had optimized our setup using AL108 and AL1210 combination for a Fluorescence detection (non-imaging application) setup. During websearch can find ACL108 and ACL 1210, which are much cheaper. Can I please have the aspheric lens prescription data - so that I can verify in Zemax that whether the alternate and cheaper substitute can meet the previous design performance.
klee  (posted 2009-10-12 14:08:37.0)
A response from Ken at Thorlabs: You are correct that the flat side should be facing the focus and the curved side should be facing collimation. We will correct this shortly.
thorlabs  (posted 2009-10-09 21:28:01.0)
Is the setup shown here correct? The Aspheric Condenser Lenses page shows two condenser lenses with curved faces toward each other. As I look at your picture, I see collimated light to the left and to the right of the pair (external to the pair) and light focused to a point between the pair. Normally the flat side of the lens faces toward focus and the curved side faces toward collimation.
apalmentieri  (posted 2009-08-14 16:15:04.0)

  • これらのレンズの焦点距離の公差は±8%です。これは製造上の公差で、波長に依存する焦点シフトによるものではありません。
  • レンズの焦点距離をその直径で割ることによって概算のF値(f/#)が求められます。
  • 開口数(NA)は、広がり角度の正弦値から算出されます。レンズは厚みがあるため、近軸近似では最外部の光線追跡はできません。
