How to select the right solution for visual inspection
This article helps users with the decision-making process when selecting a microscope as a solution for routine visual inspection. Important factors that should be considered are described.Read article
The Power of Pairing Adaptive Deconvolution with Computational Clearing
Deconvolution is a computational method used to restore the image of the object that is corrupted by the point spread function (PSF) along with sources of noise. In this technical brief, learn how the…Read article
Key Factors to Consider When Selecting a Stereo Microscope
Stereo microscopes are often nicknamed the “workhorse” of the lab or production site. Users spend many hours looking through the eyepieces inspecting, observing, documenting, or dissecting samples.…Read article
Evaluating Axon Regeneration After Brain or Spine Trauma of Mice
Damaged nerve regeneration was investigated using mouse spinal cord sections treated with compounds that counter axon growth inhibitor (AGI) proteins. The sections were screened to find active and…Read article
What Does 30,000:1 Magnification Really Mean?
One important criterion concerning the performance of an optical microscope is magnification. This report will offer digital microscopy users helpful guidelines to determine the useful range of…Read article
Eyepieces, Objectives and Optical Aberrations
For most microscope applications, there are generally only two sets of optics which are adjusted by the user, namely, the objectives and the eyepieces. Of course, this is assuming that the microscope…Read article
Koehler Illumination: A Brief History and a Practical Set Up in Five Easy Steps
The technique of Koehler Illumination is one of the most important and fundamental techniques in achieving optimum imaging in any given light microscope set-up. Although it should be routinely used as…Read article
Immersion Objectives: Using Oil, Glycerol, or Water to Overcome some of the Limits of Resolution
To examine specimens at high magnifications using the microscope, there are a number of factors which need to be taken into consideration. These include resolution, numerical aperture (NA), the…Read article
Collecting Light: The Importance of Numerical Aperture in Microscopy
Numerical aperture (abbreviated as ‘NA’) is an important consideration when trying to distinguish detail in a specimen viewed down the microscope. NA is a number without units and is related to the…Read article
Video Talk by Kurt Thorn: The Abbe Diffraction Experiment
This lecture describes the famous experiments of Ernst Abbe which showed how diffraction of light by a specimen (and interference with the illuminating light) gives rise to an image and how collection…Read article
Super-Resolution Optical Microscopy of Lipid Plasma Membrane Dynamics
Plasma membrane dynamics are an important ruler of cellular activity, particularly through the interaction and diffusion dynamics of membrane-embedded proteins and lipids. FCS (fluorescence…Read article
Microscope Resolution: Concepts, Factors and Calculation
In microscopy, the term ‘resolution’ is used to describe the ability of a microscope to distinguish detail. In other words, this is the minimum distance at which two distinct points of a specimen can…Read article
Visualization of Membrane Dynamics with Millisecond Temporal Resolution
Application Note for Leica EM ICE, Leica EM AFS2 - Electrical stimulation of neurons combined with high-pressure freezing allows physiological activation of synaptic activity and precise control over…Read article
Practical Guide for Excellent GSDIM Super-Resolution Images
Do you know that most protists and bacteria lack in one feature that each of our body cell has? Our cells are touch and communicate with one another. They send and receive a variety of signals that…Read article
Measuring the 3D STED-PSF with a new Type of Fluorescent Beads
A new type of fluorescent bead is presented by GATTAquant. These beads, called GATTA-Beads, are characterized by a small diameter (23 nm), high intensity and size uniformity. In combination with…Read article
Mirror-Enhanced Super-Resolution Microscopy
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 article
Quantifying 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 article
