There might be a macro-objective out there with wide FOV while still retaining a decent NA. I know Nikon made a system called the AZC2+ which was a large area confocal. I'm sure other vendors have similar.

I've actually got an AZ-Plan Fluor 5x from the AZC2+. Unfortunately it is designed around a 100 mm tube lens, which means that it is effectively a 10x objective in terms of focal length (f=20 mm). I was hoping to find a true 4/5x (f= ~30-40 mm).

Recent ad in Science is unclear whether Prior will be selling this, or is simply proud to have supplied "leading-edge repeatability and precision" XY (and Z?): http://www.sciencemag.org/custom-publishing/new-products/3d-microscope The Mesolens microscope makes possible for the first time the imaging of relatively large biomedically important specimens such as embryos, brain areas, or tumors, with full 3D recording of many thousands of cells. The microscope’s innovative design includes a novel apochromatic lens with an aperture-to-magnification ratio far in excess of conventional lenses used by other manufacturers. This low-magnification lens, with its exceptionally high numerical aperture, can image an entire specimen while retaining subcellular detail, thus removing the need for image stitching. The focus motor enables the Mesolens to provide highly accurate imaging in the/z/-axis. The leading-edge repeatability and precision of the microscope stage ensures that the correct position of the specimen is obtained and maintained throughout the entire imaging process. Prior Scientific www.prior-scientific.co.uk http://trends.directindustry.com/prior-scientific/project-14131-154886.html A technical paper from the University of Strathclyde (UK) evaluating the Mesolens microscope may be downloaded from https://elifesciences.org/content/5/e18659/article-info. Further information about the Mesolens microscope can be found at www.mesolens.com. enjoy, George p.s. If Brad sends you one, please ask him to send me one too.

I'm guessing that won't fit on a 'regular' microscope?
