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
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…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
Infinity Optical Systems
“Infinity Optics” refers to the concept of a beam path with parallel rays between the objective and the tube lens of a microscope. Flat optical components can be brought into this “Infinity Space”…Read article
What do you Call a Drosophila who Likes to Drink? A Bar Fly!
The thought of a Drosophoila headed to the local bar for a drink creates a funny joke, but after long hours of sorting flies under a microscope that causes eyestrain or neck pain, you may be the one…Read article
What You Always Wanted to Know About Digital Microscopy, but Never Got Around to Asking
Digital microscopy is one of the buzz words in microscopy – and there are a couple of facts that are useful to know. Georg Schlaffer, Product Manager with Leica Microsystems, has often been asked…Read article
How to Clean Microscope Optics
Clean microscope optics are essential for obtaining good microscope images. If they are dirty, the microscope should be cleaned to avoid a loss of quality. If you decide to do this yourself, you…Read article
Optical Microscopes – Some Basics
The optical microscope has been a standard tool in life science as well as material science for more than one and a half centuries now. To use this tool economically and effectively, it helps a lot to…Read article
