The Zeiss Elyra S.1 uses the technique of structured illumination (SR-SIM) to achieve resolutions two times better than that of a confocal, deconvolution or standard fluorescence microscope. Resolutions in XY of 110nm and in Z of 300nm are possible (resolution is wavelength and sample-preparation dependent), allowing users to image a volume in the sample that is 1/8 that of previous techniques.

The good news is that this super-resolution technique is a not-too-difficult jump from the dyes and sample prep techniques used for a confocal or deconvolution microscope. The Elyra S.1 can image four fluorescent colors, roughly corresponding to DAPI, FITC/GFP, Rhodamine/RFP, and CY5 (see below). SR-SIM can image to depths of 10-15 microns into a sample. Note: SR-SIM does not work well (or at all) with dimly fluorescent samples or samples that photo-bleach.
