Spherulitic crystals of hippuric acid, which were imaged with a Leica microscope using crossed polarizers, showing so-called Maltese crosses.

A Guide to Polarized Light Microscopy

Polarized light microscopy (POL) enhances contrast in birefringent materials and is used in geology, biology, and materials science to study minerals, crystals, fibers, and plant cell walls.

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

顕微鏡を知る：被写界深度

顕微鏡において被写界深度は、凹凸の変化が⼤きい構造を持つ試料をピントがあったシャープに観察・撮像するために重要なパラメータです。被写界深度は、開⼝数、解像度、倍率の相関関係によって決定され、解像度とパラメータは反⽐例の関係にあります。被写界深度と解像度のバランスが最適になるように調整することができる顕微鏡もあります。

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.

C. elegans adult hermaphrodite gonades acquired using THUNDER Imager. Staining: blue - DAPI (nucleus), green - SP56 (sperm), red - RME-2 (oocyte), magenta - PGL-1 (RNA + protein granules). Image courtesy of Prof. Dr. Christian Eckmann, Martin Luther University, Halle, Germany.
