The petrographic microscope is a compound microscope which can work with plane polarised light, meaning that it has some peculiarities. It is necessary to understand the parts and proper use of a petrographic microscope. In practice, however, not everything goes as planned. This is especially true if there are multiple users of the same microscope, either in the same class or across different classes which may be using the microscopes in different ways during the same semester or term. The petrographic microscope is much like any other microscope with the exception of a few additional attachments that are necessary for optical mineralogy determination. Figure 1 contains a diagram of a petrographic microscope similar to the type that we have in the lab.

Petrographic analysis is based on the microscopic description and With a much smaller number of labeled thin sections used in training followed by Microscope parts include eyepiece (10x), objective lenses (4x, 10x, 40x, 100x), fine and coarse focus, slide holder, condenser, iris diaphragm, illuminator, and Log in.

Petrographic microscopes have a rotating stage and a polarizing filter under the stage that transmits light vibrating usually in a N–S direction (front to back).

The petrographic, or polarizing, microscope, a compound instrument using plane-polarized transmitted light, has been applied for over a hundred years as a standard tool in the examination of rock textures and optical properties of minerals. 2.4 Parts of the Petrographic Microscope. Overview of the Microscope; The Illuminator; The Condenser and Substage Assembly; The Stage; The Focus; The Objectives and Revolving Nosepiece; The Polarizers; The (Amici-) Bertrand Lens; The Eyepieces or Oculars; The Camera; The Accessory Plates; Summary Questions; 2.5 Common Issues Using a Petrographic Microscope The camera present within the microscope captures images to reveal the finer details of the specimen. This microscope can zoom and view the density of a specimen until it is only a micrometer thick and has a magnification ranging between 1,000 – 250,000x on the fluorescent screen. This microscope needs a computer software to yield precise results. Some common rock types as seen under the microscope. These are photomicrographs - very thin slices of rock, seen in plane-polarised light, or between crossed polarisers, when the colours seen are produced by interference of light.

About any microscope can be so modified, including stereo microscopes, but the common type is a compound microscope. Those designed for geological work are also known as "petrographic" (="rock imaging") microscopes, which have accessories to assist mineral studies in thin sections of rocks.

Nikon Instruments Inc. - Nikon is a leader in microscope-based optical and imaging technologies for the life sciences and part of the Nikon Healthcare Business Division. Polarization microscopy provides a broad set of challenges when preparing to build automated workflows for sample digitization. These unique challenges, broadly arise from the orientation dependence and can be tackled using a combination of specialized equipment, automation, image processing and machine-learning based analysis techniques.
