DIC

Ein DIC-Mikroskop ist ein Weitfeldmikroskop, bei dem sich zwischen Lichtquelle und Kondensorlinse sowie zwischen Objektiv und Kamerasensor oder Okularen ein Polarisationsfilter und ein…
Image of a tartaric-acid crystal taken with polarization microscopy. Tartaric acid, a diprotic, aldaric carboxylic acid, is a naturally occurring organic compound notably found in grapes. Tartaric_acids_polarization.jpg

Das Prinzip der Polarisationsmikroskopie

Die Polarisationsmikroskopie wird in den Material- und Geowissenschaften routinemäßig eingesetzt, um Materialien und Mineralien anhand ihrer charakteristischen Brechungseigenschaften und Farben zu…
Images of the same area of a processed wafer taken with standard (left) and oblique (right) brightfield illumination using a Leica compound microscope. The defect on the wafer surface is clearly more visible with oblique illumination.

Rapid Semiconductor Inspection with Microscope Contrast Methods

Semiconductor inspection during the production of patterned wafers and ICs (integrated circuits) is important for identifying and minimizing defects. To increase the efficiency of quality control in…
Neurons imaged with DIC contrast.

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.
Mouse lung sections

Studying Pulmonary Fibrosis

The results shown in this article demonstrate that fibrotic and non-fibrotic regions of collagen present in mouse lung tissue can be distinguished better with polarized light compared to brightfield.…

Metallography – an Introduction

This article gives an overview of metallography and metallic alloy characterization. Different microscopy techniques are used to study the alloy microstructure, i.e., microscale structure of grains,…

Macroscale to Nanoscale Pore Analysis of Shale and Carbonate Rocks

Physical porosity in rocks, like shale and carbonate, has a large effect on the their storage capacity. The pore geometries also affect their permeability. Imaging the visible pore space provides…
Basalt imaged with crossed polarizers

Digital Microscopy in Earth Science

Classical polarized light (compound) microscopes can only be used for prepared samples, because the working distance they offer is insufficient for whole samples. This means that thicker and bigger…

Quality as Clear as Glass - Polarizing Microscopy in Glass Production

An exquisite beverage deserves a high-quality glass. Even the ancient Romans made artistically crafted drinking glasses. In the Middle Ages, Venetian glassmakers were famous for the purity of their…
