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…

These images show the microstructure of a hard metal with 10% cobalt which is used for heavy-duty tools. The large increase in magnification of the right image (compared to the left) has a risk of being outside the useful range or, in other words, empty magnification.

What is Empty Magnification and How can Users Avoid it

The phenomenon of “empty magnification”, which can occur while using an optical, light, or digital microscope, and how it can be avoided is explained in this article. The performance of an optical…

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.

Image of an onion flake taken with a basic Leica compound microscope after it was tested for resistance to fungus and mold growth following part 11 of the ISO 9022 standard.

ISO 9022 Standard Part 11 - Testing Microscopes with Severe Conditions

This article describes a test to determine the robustness of Leica microscopes to mold and fungus growth. The test follows the specifications of the ISO 9022 part 11 standard for optical instruments.

Fluorescence microscope image of a life-science specimen

An Introduction to Fluorescence

This article gives an introduction to fluorescence and photoluminescence, which includes phosphorescence, explains the basic theory behind them, and how fluorescence is used for microscopy.

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.
