Quality assurance during production in a manufacturing plant.

Quality Assurance Improvement Across Industries

Precision is paramount. Imagine a pacemaker that fails mid-operation or a semiconductor flaw that causes a critical system crash. In industries, such as medical devices, electronics, and…

Image of roundworm C. elegans acquired with a M205 FA fluorescence automated stereo microscope in combination with Rottermann contrast. Areas labelled with mCherry are seen as reddish purple.

A Guide to C. elegans Research – Working with Nematodes

Efficient microscopy techniques for C. elegans research are outlined in this guide. As a widely used model organism with about 70% gene homology to humans, the nematode Caenorhabditis elegans (also…

Some 2D measurements, e.g., lengths and areas, made on a PCB sample with a Leica measurement microscope using the Enersight software.

How to Select the Right Measurement Microscope

With a measurement microscope, users can measure the size and dimensions of sample features in both 2D and 3D, something crucial for inspection, QC, failure analysis, and R&D. However, choosing the…

Example of calibrating a microscope at a higher magnification value using a stage micrometer.

Microscope Calibration for Measurements: Why and How You Should Do It

Microscope calibration ensures accurate and consistent measurements for inspection, quality control (QC), failure analysis, and research and development (R&D). Calibration steps are described in this…

A fruit fly (Drosophila melanogaster) observed with an Ivesta 3 stereo microscope during fly pushing (sorting of the flies). The scale bar length is 1 mm. Image courtesy of M. Benton, EMBL, Heidelberg, Germany.

A Guide to Using Microscopy for Drosophila (Fruit Fly) Research

The fruit fly, typically Drosophila melanogaster, has been used as a model organism for over a century. One reason is that many disease-related genes are shared between Drosophila and humans. It is…

Zebrafisch-Forschung

Für optimale Ergebnisse während der Bewertung, Sortierung, Manipulation und Bildgebung von Modellorganismen ist es entscheidend feine Details und Strukturen genauestens zu erkennen. Das bildet die…

Präpariermikroskope

Wenn Sie Präparationen durchführen, verbringen Sie oft viele Stunden an den Okularen eines Präpariermikroskops. Bei Leica Microsystems können Sie aus einer Vielzahl von Mikroskopen und einem…

Area of a printed circuit board (PCB) which was imaged with extended depth of field (EDOF) using digital microscopy.

Depth of Field in Microscope Images

For microscopy imaging, depth of field is an important parameter when needing sharp images of sample areas with structures having significant changes in depth. In practice, depth of field is…

Image of a Siemens star, where the diameter of the 1st black line circle is 10 mm and the 2nd is 20 mm, taken via an eyepiece of a M205 A stereo microscope. The rectangles represent the field of view (FOV) of a Leica digital camera when installed with various C-mounts (red 0.32x, blue 0.5x, green 0.63x).

Understanding Clearly the Magnification of Microscopy

To help users better understand the magnification of microscopy and how to determine the useful range of magnification values for digital microscopes, this article provides helpful guidelines.
