About Polarization

Utilizing the polarization method in light microscopy reveals a specific kind of information about the sample. Applying this contrast method, we less often talk about structure size and shape, resolution power or even a specific staining. In case of transparent samples, polarization contrast in first instance has one subject in mind: the potential BIREFRINGENCE of the sample and its implications on a structural insight.

BIREFRINGENCE is a widespread phenomenon, found in nature as well as in man-made materials. Starch grains, fibers, crystals and minerals, plastic sheets and die cast components, the structural basis is always the same: embedded within an amorphous matrix, structures with an intrinsic geometric pattern cause an impact on the speed of light and its oscillating direction when sent through the sample.

Chemical cristals

A sponge a phoenix?

All sponges possess a remarkable ability to regenerate lost parts. A piece cut from the body of a sponge is capable of growing into a complete sponge. This power of regeneration helps the sponges to repair the damage caused in the harsh environment.

Transition of lava on Mount Etna

Limonite is a mineral consisting of various iron oxides. Limonite is yellow, ochre, brown or blackish colored by iron oxide.

Volcanic rock of Mount Etna can be transformed into Limonite, which is called like that because of its yellow brownish color. The Limonite is mainly produced by the oxidation of iron containing lava rocks by weathering, facilitated by splitting and pulverizing of the rock because of the penetration of the roots of vegetation enabling oxygen and humidity to enter.
