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…
Left: Tissue cells marked with an immunolabel (FITC) illuminated with wide-band UV excitation. Note the tissue structure with blue autofluorescence. Right: Same tissue and same immunostaining with FITC label illuminated with epi-illumination using narrow-band blue (490 nm) light. Note the increased image contrast (Ploem, 1967)

Milestones in Incident Light Fluorescence Microscopy

Since the middle of the last century, fluorescence microscopy developed into a bio scientific tool with one of the biggest impacts on our understanding of life. Watching cells and proteins with the…

A Brief History of Light Microscopy

The history of microscopy begins in the Middle Ages. As far back as the 11th century, plano-convex lenses made of polished beryl were used in the Arab world as reading stones to magnify manuscripts.…
