A petrographic microscope is a type of optical microscope that uses polarized light to identify rocks and minerals in thin section and to investigate microscopic textures and features that are present in minerals and rocks. This module provides an overview of the parts of a petrographic microscope, including the purpose of each part.

Figure 1 contains a diagram of a petrographic microscope similar to the type that we have in the lab. Below is a brief explanation of the more important parts of the microscope: 1. Petrography is a branch of petrology that focuses on detailed descriptions of rocks. Someone who studies petrography is called a petrographer. The mineral content and the textural relationships within the rock are described in detail. The classification of rocks is based on the information acquired during the petrographic analysis.

THE BEST "AFFORDABLE" PETROGRAPHIC MICROSCOPES OF THE 1970S TO 1990S by J. Gregory McHone, USA Introduction Relatively few of us are lucky enough to have and use a wide range of makes and models of microscopes. Work-place microscope labs often have little variety in brands or models, so as to reduce costs for maintenance and accessories. But Petrography is a branch of petrology that focuses on detailed descriptions of rocks. Someone who studies petrography is called a petrographer. The mineral content and the textural relationships within the rock are described in detail.

A petrographic microscope is a type of optical microscope used in petrology and optical mineralogy to identify rocks and minerals in thin sections. The microscope is used in optical mineralogy and petrography, a branch of petrology which focuses on detailed descriptions of rocks. The method is called " polarized light microscopy " (PLM). Although petrographic microscopes can look different from each other, since they all function in a similar manner, the parts should be located in similar positions from microscope to microscope. Understanding the function of each part of the microscope will help when making petrographic observations and measurements. The petrographic microscope is much like any other microscope with the exception of a few additional attachments that are necessary for optical mineralogy determination.
