Petrographic Microscopes: Focusing on their Uses

April 12, 2018 By Eileen Ross

The right job requires the right tool. That’s why petrographic microscopes are the instrument of choice when your work requires looking at rocks and minerals in extensive detail.

Petrographic microscopes allow researchers in optical mineralogy and petrography to look closely at rocks and minerals in thin sections. Users can use these microscopes to get incredibly clear and detailed looks at rocks to determine the mineral content and textural relationship within the rock. This helps geologists understand the origin of the rock and, as a result, the world in whole, allowing petrologists to create incredibly detailed descriptions of various types of rocks.

Petrographic microscopes are also favored as they are built with optical parts that do not add unwanted polarizing effects. True petrographic microscopes typically include a piece called a Bertrand lens. This focuses and enlarges a figure, which is useful when looking at complex mineral and rock structures. The Bertrand lens can typically be removed to make a direct observation, as well, depending on the needs of the microscope’s user.

Users can also make other modifications to the microscope’s optical system. Petrographic microscopes allow for different filers to be inserted between the polarizers to identify positive and negative birefringence.

Petrographic microscopes provide a unique view on the world that many do not get to see. If your organization or institution is looking for a new piece of equipment to help with your studies, petrographic microscopes are the right choice for you.

If you are interested in getting a petrographic microscope, or any other type of microscope, look to Absolute Clarity & Calibration. We sell both new and refurbished microscopes, along with specialized products, such as stereo and gemological microscopes. With accompanying parts, such as stands, splitters and bulbs, we have everything you need to get a clearer look at any sample. To learn more, call us today at 860-583-0502.
