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. Although all petrographic microscopes have common parts and functions, there are many brands of microscope, each of which may look different. If petrographic microscopes are maintained and handled carefully, they can last for literally generations of students.

If petrographic microscopes are maintained and handled carefully, they can last for literally generations of students.
The use of a polarizing microscope to analyze the optical properties of crystals is a standard technique in mineralogy and petrography.
Here we document the use of a petrographic microscope to observe and image the photoluminescence (PL) response of whole zircon grains excited under ultraviolet (UV) light, and the utility of this PL response in selecting grains for geochronology.
