HyVolution – Super-Resolution Imaging with a Confocal Microscope
Since the invention of the microscope, there has been continual discussion about the possibility of showing more detailed features of specimens as compared to just magnifying them. In this article we describe the HyVolution concept and how the combination of confocal multiparameter fluorescence imaging at the confocal super-resolution regime with psf-based real deconvolution allows high-speed multicolor imaging with a resolution down to 140 nm.
HyVolution – the Smart Path to Confocal Super-Resolution
Super-resolution refers to any device or method that can resolve better than the classical Abbe limit. Apart from infinite super-resolution techniques such as STED (stimulated emission depletion) and SMLM (single-molecule localization methods) that can theoretically resolve to any detail, there are also methods for limited super-resolution. Here we present HyVolution by Leica, which merges optical super-resolution and computational super-resolution. The optical part is provided by confocal microscopy, and the computational part by deconvolution. Lateral resolution of 140 nm is demonstrated. HyVolution offers multiple fluorescence recording in truly simultaneous mode.

Super-sensitive detection with low noise plus Huygens deconvolution is the key to resolving structures down to 140 nm with a confocal microscope. The result is crisp images full of contrast revealing details, which cannot be seen with confocal microscopy.
