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…

Introduction to Widefield Microscopy

This article gives an introduction to widefield microscopy, one of the most basic and commonly used microscopy techniques. It also shows the basic differences between widefield and confocal…

Optimization of the Interplay of Optical Components for Aberration Free Microscopy

Optical microscopes are used to magnify objects which are otherwise invisible for the human eye. For this purpose high quality optics is necessary to achieve appropriate resolution. However, besides…
Multicolor image of a Confetti Mouse recorded with the new SP8 DIVE with the 4Tune spectral detector. The adaptation to the transgenic markers allows to achieve more contrast and depth for multi-color in vivo deep imaging. Sample courtesy of Jacco van Rheenen, University of Utrecht, NL.

About the Most Important Considerations When Imaging Deep Into Mouse Tissue

When operating a confocal microscope, or when discussing features and parameters of such a device, we inescapably mention the pinhole and its diameter. This short introductory document is meant to…

Primary Beam Splitting Devices for Confocal Microscopes

Current fluorescence microscopy employs incident illumination which requires separation of illumination and emission light. The classical device performing this separation is a color-dependent beam…

Photoactivatable, Photoconvertible, and Photoswitchable Fluorescent Proteins

Fluorescent proteins (FPs) such as GFP, YFP or DsRed are powerful tools to visualize cellular components in living cells. Nevertheless, there are circumstances when classical FPs reach their limits.…
Pinhole diameter and diffraction pattern.

Pinhole Effect in Confocal Microscopes

When operating a confocal microscope, or when discussing features and parameters of such a device, we inescapably mention the pinhole and its diameter. This short introductory document is meant to…
Comparison when observing a rodent model organism with a Greenough versus CMO (common main objective) stereo microscope for a task like surgery.
