Polarizing microscopes are often also referred to as petrographic microscopes. It is for the reason that their main application is in studying rocks and minerals under polarized light. The study of optical mineralogy uses petrographic microscopes to produce polarized light for analysis and identification on slides of rock and mineral thin sections. Cross polarization can be obtained with our polarized light microscopes. This is done by turning the polarizer and the analyzer of the microscope at 90 degrees to each other. This is called the extinction angle. At this angle, most of the light transmission is blocked by the polarized filters. A polarized light microscope set at this extinction angle is then able to view thin sections of the specimens and their colorations. There are several useful applications for polarized microscopes.

Applications for polarized light microscopes include rock and mineral identification. Also for medical applications, such as in viewing microscopic crystals in urine, biochemistry and biomedical research are fields that find the polarizing microscope very useful. The polarizing microscope is likewise utilized in studying meteorite thin specimens, in the filed of geology and geological engineering. This microscope is even used in the petroleum industry. There are several models of polarizing microscopes, each having its own unique features designed to cater to the needs of its users. An example of this microscope is the Infinity Corrected Polarizing Microscope. This type of polarizing microscope produces excellent bright and clear images through its high optics quality. This superior quality microscope is said to be great for Geology, Petrology, Mineralogy, Toxicology, Pharmaceutics and Forensic Medicine fields. This polarizing microscope has larger 30mm eyepiece ocular tubes as one of its special features. Most compound scopes usually only have 23mm eyepiece ocular tubes.

The larger size of eyepiece ocular tubes of this polarizing microscope allows for less eye strain for the user. This gives an advantage of much easier viewing and a larger and better quality specimen image. The Infinity Corrected Polarizing microscope has a 30 degree inclined trinocular head and is rotatable to up to 360 degrees. It has a 50 to 80mm interpupillary distance allowable adjustment between the users eyes. It even has a diopter adjustment to correct for specific vision needs. This type of microscope has a rack and pinion steel gears that allow easy and better condenser movement. The Infinity Corrected polarizing microscope has a blue filter base illuminator system that has a high 30W tungsten halogen transmitted base illumination. It makes use of Koehler illumination system with a focusable field diaphragm on its base that allows better control and more efficient use of light source for improved image quality.

The Infinity Corrected Polarizing microscope has objective centering screws on its nosepiece. This allows for precise and easy alignment. It is also a color corrected infinity optical system aside from just it having an infinity corrected objectives. This allows for better quality of images. It has a built in analyzer with the capability for removal from the optical path. Also, as a special feature, it has a brightfield/polarizing selectable knob for easily changing from brightfield to polarizing light. With this microscope, you can easily switch between plane polarized and cross polarized illumination. The Infinity Corrected Polarizing Microscope comes with a trinocular photography port which allows you to photograph your specimens. It is also a complete digital video microscopy system. With its USB port, oyu can also your images in the computer for everyone to see. High resolution images on your monitor or TV can also be seen and stored for later use. With this USB digital microscope, you can videotape images and capture still pictures as you study.
