Spherulitic crystals of hippuric acid, a carboxylic acid found in urine, imaged with crossed polarizers showing so-called Maltese crosses. Spherulitic structures are formed by radial crystal growth starting from a central crystal nucleus. Image recorded with a DM4 P microscope using transmitted light, 20x Plan Fluotar objective, and polarizers.

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…
