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.

Leitz Laborlux: Tartaric acids, polarization contrast

The Polarization Microscopy Principle

Polarization microscopy is routinely used in the material and earth sciences to identify materials and minerals on the basis of their characteristic refractive properties and colors. In biology,…

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…

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.

Spirogyra algae (Conjugation), Transmitted Light Differential Interference Contrast.

DIC

Um microscópio DIC oferece microscopia de campo amplo e tem um filtro de polarização e prisma Wollaston entre a fonte de luz e a lente do condensador e também entre a lente objetiva e o sensor da…

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.…

Radially grown sugar crystals which have been imaged with a Leica microscope using circular polarized light.

Polarizing Microscope Image Gallery

Polarized light microscopy (also known as polarizing microscopy) is an important method used in different fields, including research and quality assurance. It goes beyond just producing images at high…

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…
