SR-SIM Super Resolution Image
ELYRA S.1 - SR-SIM

Super-resolution Structured Illumination Microscopy (SR-SIM) images any fluorophore - with up to twice the resolution of a conventional light microscope.

In SR-SIM, a grid pattern is projected onto the image plane. The grid structures interfere with sample structures, creating Moiré fringes. These contain high frequency information (synonymous with high resolution information) transformed down to low frequencies that can be captured by the optical system. Then all you need do is back-compute these lower frequencies to their true value in the final image. In this way you can double the resolution in all three directions.

Put Flexibility First with Structured Illumination 

ELYRA S.1 images any fluorophore – with up to twice the resolution of a conventional light microscope.

You have invested a lot of time and energy in producing fusion proteins and multicolor staining protocols that are adapted to your experimental system. Now, with ELYRA S.1, you capture superresolution microscopy data with ease, using samples that may already be available in your lab's freezer. Specially-designed gratings give you the best resolution for each wavelength. Do you need Z-sectioning for 3D data acquisition? A fast, light-efficient detection? Then ELYRA S.1 is your ideal choice.
