Key Factors to Consider When Selecting a Stereo Microscope
Stereo microscopes are often nicknamed the “workhorse” of the lab or production site. Users spend many hours looking through the eyepieces inspecting, observing, documenting, or dissecting samples.…Read article
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
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…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
A Brief History of Light Microscopy – From the Medieval Reading Stone to Super-Resolution
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.…Read article
Using Telecentric Optical Systems to Optimize Industrial Image Accuracy and Reproducibility
When the first multi-lens microscopes were invented in 1590, scientists marveled at their new ability to SEE small objects and features in the natural world that were previously invisible to the eye…Read article
