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。

Automated Laser Microdissection for Proteome Analysis

Deep Visual Proteomics Provides Precise Spatial Proteomic Information

Despite the availability of imaging methods and mass spectroscopy for spatial proteomics, a key challenge that remains is correlating images with single-cell resolution to protein-abundance…

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…
