Features
- Available with Antireflection Coating for 400 - 700 nm or 650 - 1050 nm
- Ideal for Image Relay, NA Conversion, or Image Magnification
- Different Magnifications for Imaging and Numerical Aperture Matching
- Focal Lengths Clearly Marked for Quick Identification
- Compatible with Thorlabs' SM05- or SM1-Threaded Components
Thorlabs' Matched Achromatic Pairs combine two of our unmounted, cemented achromatic doublets for image relay, NA conversion, or image magnification. Achromatic doublets are designed for infinite conjugate ratios, but are ideal for finite conjugate applications when used in pairs. In finite conjugate applications, both the object and image are a finite distance from the lens pair.
These pairs are housed in SM05 (0.535"-40) or SM1 (1.035"-40) threaded housings, which have outer diameters of Ø0.7" and Ø1.2", respectively. The housing is engraved with the part number, focal lengths, and magnification of the pair, allowing for easy identification. Since the lenses are pre-mounted, there is no need to handle the glass optics, making these achromats ideal for integration into a host of OEM applications.
To achieve the specified magnification, orient the mount so that the end of the housing with the shorter focal length lens is closer to the object. If the lens is used in the reverse direction, the inverse magnification will be achieved. If the two lenses have the same focal length, either orientation of the housing will produce 1:1 magnification.

The shaded region indicates the specified 400 - 700 nm wavelength range for optimum performance.
The matched Achromatic Pairs offer superior performance in a simplified package compared to traditional spherical singlets when used for image relay. In the first set of plots to the right, two LA1509-A N-BK7 plano-convex lenses are optimized to image the Thorlabs logo. In the second set of plots, the MAP10100100-A is used to image the logo, and the improvement is obvious. The doublet pair in the MAP configuration is able to minimize the spherical and chromatic aberrations to produce a better image.

(posted 2024-04-04 09:52:33.82) Is it possible to adjust the distance of the two lenses? If the distance is different from the correct tc value, will it be a spherical aberration?
Thanks! Jonas Euchner
(posted 2023-10-17 07:07:13.497) I believe the Example Focal Length Shift Plot for the MAP107575-A is incorrect in the Performance tab. It lists the focal length shift in µm. After running the analysis in Oslo, with additional tests in TracePro, I believe the axis should be in mm not µm.
This is more in line with the performance observed in the lab, and more similar to the performance of the single AC254_75_A lens. If I am correct, please update the performance graph as it mislead us in believing this Steinhell lens has superior chromatic focal shift jdelia
(posted 2023-10-18 10:16:40.0) Thank you for pointing this out to us. You are correct, the y-axis of the graph in question should be in mm. We are looking into updating the graph accordingly. Syeda Aimen Abbasi
(posted 2022-11-10 11:15:03.67) Dear Sir/Madam,
We have the MAP103050-A lens. But the lens is mounted within the holder and is around 7.4mm from the edge of the holder. This is a concern for our optical design since we want our object to be as close to the proximal lens as possible (within 5mm).
Is there a way to reduce the distance from the lens to the tip of the holder to, say 1 or 2mm?
If not, are any other products that has the same lens, but does not have such a larger distance within the holder?
Thank you very much for your time! ksosnowski
(posted 2022-11-12 12:29:13.0) Hello Syeda, thanks for reaching out to Thorlabs. The distance from edge of lens to edge of housing can be found on the CAD drawing for each part. The housing itself is designed to properly space the pair of doublets, so they cannot be adjusted as in a standard lens tube. Your local tech support team is reaching out to discuss this application further. Alastair MacDowell
(posted 2020-02-24 19:07:41.98) I note the lack of a Field of View specification. How good are these lenses for imaging ? eg for the MAP107575-A llamb
(posted 2020-02-27 09:20:16.0) Thank you for your feedback. Most of the achromatic doublets are not designed with any field of view, so they are not ideal for strict imaging applications. We would recommend a camera lens like our MVL- series for imaging purposes in order to achieve a field of view. Intermediate images have a finite size, so a relay lens needs to be able to capture the off-axis ray bundles. khatoniar.mandeep
(posted 2019-01-12 14:00:19.113) Can these doublet pairs be used as a lens relay ? That is to mantain collimation of an already collimated beam or correct for beam divergences for collimated beams (4f system) ? YLohia
(posted 2019-04-04 09:06:48.0) Hello, thank you for contacting Thorlabs. These lenses can be used as a relay lenses, but not in collimated space. The spacing between the two lenses would have to be the sum of the focal lengths for this to be possible. It appears that you may be looking for a beam expander, as the divergence of a collimated beam is reduced as the beam diameter increases. tillsten
(posted 2017-07-05 13:14:07.06) Can the 30mm diameter doublets be used to focus the light from a non-collimated white light LED? tfrisch
(posted 2017-08-04 10:26:49.0) Hello, thank you for contacting Thorlabs. These pair of achromatic doublets would create a magnified image of the LED emitter when the first lens is one focal length from the LED. I will reach out to you directly to discuss your application. user
(posted 2015-03-15 01:06:26.497) Hello, are these usable to magnify a low power collimated beam? besembeson
(posted 2015-03-26 03:55:53.0) Response from Bweh at Thorlabs USA: These are typically used for image relay, NA conversion or image magnification. For magnification of collimated sources, you would need one of our beam expanders at the following link: http://www.thorlabs.us/navigation.cfm?guide_id=2023 tcohen
(posted 2012-03-28 11:31:00.0) Response from Tim at Thorlabs: Thank you for your feedback! I have contacted you with the focal length shift data and an OPD plot for spherical aberration. Simone.Rupp
(posted 2012-03-27 05:03:34.0) Dear Thorlabs team,
are there any data available that allow me to estimate the focal length shift due to chromatic aberration? For some other Thorlabs products (e.g. achromatic triplets) those data are available as excel files.
I'm especially interested in the MAP107575-A in a wavelength range from 500 or 600 nm to 700 nm.
If there are any numbers quantifying the effect of spherical aberrations, these would be interesting for me, too.
Thank you! apalmentieri
(posted 2009-10-13 14:25:42.0) A response from Adam at Thorlabs: I am currently checking with our optics division and hope to provide you with more information soon. I will respond to your email address and this feedback post. roberto.nesci
(posted 2009-10-13 14:02:21.0) how large is the corrected focal plane of this optical assembly?
