Multiphoton microscopy of an unstained mouse skin section acquired using the 4Tune detector.

Mission Impossible Accomplished: Tunable Colors for Non-descanning Detection

Leica Microsystems’ 4Tune detector, the key component of the SP8 DIVE Deep In Vivo Explorer, provides spectrally tunable image recording with non-descanning detection. An innovative solution for…

Koehler Illumination: A Brief History and a Practical Set Up in Five Easy Steps

In this article, we will look at the history of the technique of Koehler Illumination in addition to how to adjust the components in five easy steps.

Mammalian cell culure. Phase contrast and fluorescence image.

Introduction to Mammalian Cell Culture

Mammalian cell culture is one of the basic pillars of life sciences. Without the ability to grow cells in the lab, the fast progress in disciplines like cell biology, immunology, or cancer research…

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…

Interview with Dr. Shigeki Watanabe on Research in Synaptic Membrane Dynamics

Dr. Shigeki Watanabe, principle investigator of the department of Cell Biology at the Johns Hopkins University School of Medicine in Baltimore, held a workshop in Zürich, Switzerland on methods to…

Laser Beam Shaping for Multicolor Multiphoton Microscopy

Multiphoton Microscopy is one of the current hot topics in life science research. The new Leica TCS SP8 DIVE from Leica Microsystems presents a series of beneficial new innovations, including a freely…

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…

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…
