Central Nervous System (CNS) Development and Activity in Organisms
This article shows how studying central nervous system (CNS) development in Drosophila-melanogaster embryos expressing a GCaMP calcium indicator in the neurons can be improved with a THUNDER Imager.
What is the Patch-Clamp Technique?
This article gives an introduction to the patch-clamp technique and how it is used to study the physiology of ion channels for neuroscience and other life-science fields.
Differential Interference Contrast (DIC) Microscopy
This article demonstrates how differential interference contrast (DIC) can be actually better than brightfield illumination when using microscopy to image unstained biological specimens.
Digital Inspection Microscope for Industrial Applications
Factors users should consider before choosing a digital inspection microscope for industrial applications, including quality control (QC), failure analysis (FA), and R&D, are described in this…
Going Beyond Deconvolution
Widefield fluorescence microscopy is often used to visualize structures in life science specimens and obtain useful information. With the use of fluorescent proteins or dyes, discrete specimen…
Microscope Illumination for Industrial Applications
Inspection microscope users can obtain information from this article which helps them choose the optimal microscope illumination or lighting system for inspection of parts or components.
Phase Contrast and Microscopy
This article explains phase contrast, an optical microscopy technique, which reveals fine details of unstained, transparent specimens that are difficult to see with common brightfield illumination.
Immersion Objectives
How an immersion objective, which has a liquid medium between it and the specimen being observed, helps increase the numerical aperture and microscope resolution is explained in this article.
How to Determine Cell Confluency with a Digital Microscope
This article shows how to measure cell confluency in an easy and consistent way with Mateo TL, increasing confidence in downstream experiments.
Microscope Resolution: Concepts, Factors and Calculation
This article explains in simple terms microscope resolution concepts, like the Airy disc, Abbe diffraction limit, Rayleigh criterion, and full width half max (FWHM). It also discusses the history.

Leitfaden zur Fluoreszenzlebensdauer-Imaging-Mikroskopie (FLIM)
The fluorescence lifetime is a measure of how long a fluorophore remains on average in its excited state before returning to the ground state by emitting a fluorescence photon.
Cleanliness Analysis for Particulate Contamination
Devices, products, and their components fabricated in many industries can be quite sensitive to contamination and, as a result, have stringent requirements for technical cleanliness. Measurement…
