Visible Achromatic Doublet Pairs

General Specifications
Design Wavelengths486.1, 587.6, and 656.3 nm
Focal Length Tolerance±1%
Reflectivity
(400 - 700 nm)		Ravg < 0.5%

Features

  • Broadband AR Coating for 400 - 700 nm Range
  • Ideal for Image Relay, NA Conversion, or Image Magnification
  • Different Magnifications for Imaging and Numerical Aperture Matching
  • Focal Lengths Clearly Marked for Quick Identification
  • SM05- or SM1-Threaded for Compatibility with Thorlabs Mechanics
  • Also Available: NIR Doublet Pairs with AR Coating for 650 - 1050 nm Range

Our 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. Thorlabs' Matched Achromatic Pairs combine two of our stock achromatic doublets for image relay systems, NA conversion, or image magnification.

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, thereby 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.

When determining the proper orientation of the lens pair, please note that the magnification is specified as f1:f2. Therefore, to enlarge an object, place the end of the housing with the f1 engraving such that it faces the source; for a reduced image, orient the mount so the f2 engraving faces the object. Achromatic pairs with a 1:1 magnification are bidrectional.

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.

Example Focal Length Shift Plot

The plot to the right shows the focal length shift vs. wavelength for our MAP107575-A Lens Pair. An Excel version of this data is also available.

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.

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!
