Axial excitation confinement beyond the diffraction limit is crucial to the development of next-generation, super-resolution microscopy. STimulated Emission Depletion (STED) nanoscopy offers lateral…Read articleQuantifying the Resolution of a Leica SR GSD 3D Localization Microscopy System with 2D and 3D Nanorulers
DNA origami based nanorulers produced by GATTAquant are common standards to test the achievable spatial resolution of super-resolution microscopes. Recently the nanorulers were used to test the…Read articleSuper-Resolution Mapping of Neuronal Circuitry With an Index-Optimized Clearing Agent
Super-resolution imaging deep inside tissues has been challenging, as it is extremely sensitive to light scattering and spherical aberrations. Here, we report an optimized optical clearing agent for…Read articleHyVolution – 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…Read articleHyVolution – 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…Read articlePathways to Optical STED Microscopy
STED nanoscopy has evolved to a highly versatile tool for the observation of the living cell, more and more finding its way into state-of-the-art optical imaging facilities in biomedical research…Read articleMulti-Images Deconvolution Improves Signal-to-Noise Ratio on Gated Stimulated Emission Depletion Microscopy
Time-gated detection, namely, only collecting the fluorescence photons after a time-delay from the excitation events, reduces complexity, cost, and illumination intensity of a stimulated emission…Read articleSuper-Resolution – On a Heuristic Point of View About the Resolution of a Light Microscope
Since super-resolution has become one of the most favored methods in biomedical research, the term has become increasingly popular. Still, there is much of confusion about what is super-resolution and…Read articleVideo Talk by Jeff Lichtman: Point Spread Function
An infinitesimally small point appears in the microscope as a spot with a certain size, blurred in the z-direction and with concentric rings around it. This "point spread function" reveals many of the…Read articleFusionOptics in Neurosurgery and Ophthalmology – for a Larger 3D Area in Focus
Neurosurgeons and ophthalmologists deal with delicate structures, deep or narow cavities and tiny structures with vitally important functions. A clear, three-dimensional view on the surgical field is…Read articleVideo Talk by Jeff Lichtman: Resolution in Microscopy – Wave Optics and the Diffraction Limit
Light has properties of particles and waves. Understanding the wave nature of light is essential to understanding the workings of a microscope. This lecture describes Huygens Wavelets,…Read articlePinhole Geometry: Four Corners are Perfect
Square and hexagonal pinholes provide identical image signal levels, if the geometries are compared in a sensible manner. The amount of light passing the pinhole depends on the area of that aperture,…Read articleA Guide to Super-Resolution Fluorescence Microscopy
For centuries, cell biology has been based on light microscopy and at the same time been limited by its optical resolution. However, several new technologies have been developed recently that bypass…Read articleDigital Cameras
Manufacturers digital cameras race to outdo each other with ever-increasing numbers of megapixels. The world record for professional medium format digital cameras has now surpassed 60 megapixels per…Read articleBeware of "Empty" Magnification
This article explains how to avoid the phenomen of "empty magnification" in microscopy.Read article
