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…

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…
