Eyepiece
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.
Intensity distribution (arbitrary color coding) of an image of two points where the distance between them corresponds to the Rayleigh criterion.

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.
Spherical aberration describes the fact that waves which pass through the centre of the lens are refracted less than the waves which pass through the edges of the curved lens.

Eyepieces, Objectives and Optical Aberrations

This article covers the components of the eyepieces and how to adjust them correctly to suit your eyes.

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…
Infinity port

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”…
Cleaning microscope optics

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…
