Petrological Microscope QMM-500

 

Viewing Head: 30 degree inclined fixed Trinocular Head

Mechanical Stage: 360 degree rotating circular stage

Observation Technique: (Transmitted light Bright Field (BF), Dark Field (DF) & Polarization (POL) and phase contrast techniques

Eyepiece: A pair of WF 10X/22mm FOV.

Description

 

Polarized light microscopy can mean any of a number of optical microscopy techniques involving polarized light. Simple techniques include illumination of the sample with polarized light. Directly transmitted light can, optionally,
be blocked with a polariser orientated at 90 degrees to the illumination. More complex microscopy techniques which take advantage of polarized light
include differential interference contrast microscopy and interference reflection microscopy. Scientists will often use a device called a polarizing
plate to convert natural light into polarized light.
These illumination techniques are most commonly used on birefringent samples where the polarized light interacts strongly with the sample and so generatincontrast with the background. Polarized light microscopy is used extensively in optical mineralogy
