Our 1X telecentric objective is ideal for machine vision applications (see Telecentric Tutorial tab), while our 2X and 4X objectives have high numerical apertures (NA), making them ideal for widefield imaging. These objectives are designed for use with a tube lens focal length of 200 mm and have optical elements that are AR-coated for improved transmission.

Thorlabs' super apochromatic microscope objectives provide axial color correction in the visible range and a flat field of focus in a variety of imaging modalities without introducing vignetting. Magnifications Specified for Use with a 200 mm Tube Lens.Ideal for Brightfield, Fluorescence, Multiphoton, and Confocal Imaging Applications.Infinity-Corrected Super Apochromatic Design.If you use the Zemax models provided here, we would appreciate it if you could cite this paper as well as the figshare fileset.Thorlabs maintains the labeling convention shown above for all of its super apochromatic microscope objectives. (See the Objective Tutorial tab for more information about microscope objective types.) Features This paper provides a detailed description of how these Zemax models were produced and analyzed.

20X 0.5NA ZEMAX FILE UPDATE
Update (, Description only): The related paper on “Comparative analysis of imaging configurations and objectives for Fourier microscopy” by Jonathan A. In all cases, this required a shift in the position of the Bertrand Lens of ~1cm further from the tube lens. Specifically, the position of the Bertrand Lens has been modified so that it correctly images the BFP image onto the real image plane. Additionally, for all multiconfiguration files, the "before image plane" configuration has been modified. Update (, Version 2, filenames annotated with "_v2" suffix): For all objectives files and the objective catalog, the immersion oil layer semi-diameter has been changed to float so as to prevent unrealistic vignetting that may otherwise occur.
