The light from an M530L3 530 nm LED is focused onto a ground glass diffuser by an ACL5040U-A aspheric condenser lens. The beam is then roughly collimated by a second ACL5040U-A lens. The square image of the LED can be seen on the surface of the diffuser. After the diffuser, the beam is uniform. Both condenser lenses are mounted in SCL04 self-centering lens mounts.

Features

  • Aspheric Condenser Lenses with Larger Apertures and Higher NA than Spherical Lenses
  • 13 Different Diameters From 10 to 75 mm Available
  • NA from 0.52 to 0.79
  • Available Uncoated or AR-Coated for 350 - 700 nm or 650 - 1050 nm
  • Fabricated from B270 Optical Crown Glass (380 - 2100 nm)

High-Efficiency Illumination Applications

  • Light Collection / Condensing
  • Projection
  • Detection

Thorlabs' Aspheric Condenser Lenses offer larger apertures, higher NA, and lower f/# ratios than spherical lenses. Therefore, these lenses are ideal for high-efficiency illumination applications or collimating light from a lamp, LED, or similar light source. Our condensers are sold in diameters from 10 to 75 mm and are available uncoated for 380 - 2100 nm or with an AR coating for 350 to 700 nm (-A Coating) or 650 to 1050 nm (-B Coating). The reflectance curves for the coated versions can be found by clicking on the graph icons in the table to the right.

Because of the shorter focal lengths and a lower f/# than other lenses, condenser lenses can be used in close proximity to one another or other optical elements, which makes them ideal for focusing light onto a detector or other light collection element. The lens surface is precision molded on the aspheric side while the plano or spherical convex side is ground and polished. For best performance, the flatter side of the lens should face the source. Please note that although the B270 substrate transmits from 380 - 2100 nm, these lenses are designed for use at visible wavelengths; focal shift plots are provided in the tables below for each lens for performance at other wavelengths. 

For more demanding applications, we recommend our CNC-Polished, Precision Aspheres (available with N-BK7, S-LAH64, or UV Fused Silica substrates), which offer diffraction-limited performance at their design wavelength. Thorlabs also offers aspheric condensers with a polished diffuser surface on the plano side

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")?

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.

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.

Posted Date: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.

Is the focus length of a lens is wavelength dependent? If it is ,how is the relationship between them?

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.

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.

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.

Response to Javier: I guess my question should be: Can I know where the principal planes are?
Poster:Javier
Posted Date: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.

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.

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.
Poster:thorlabs
Posted Date: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.
