Ore Microscopes is your source for microscopes with the ability to view thick polished rock and mineral specimens under polarized light. A standard polarizing microscope has the ability for only transmitted polarized light, meaning the light must go through the rock and mineral thin section. If the ore sample is thick and opaque, then no light will transmit, so it must be viewed with reflected incident illumination. An ore microscope has the ability to view the birefringent mineral specimen in reflected polarized light. Our ore microscopes also have the added feature of using transmitted polarized light such as used in a polarized light microscope. Rock and mineral identification requires polarized light, and specifically, the ability to initially polarize the incoming light with a polarizer, then, before the eyepieces, run the light beam through a second polarized filter called an analyzer. The angle of rotation of the polarizer and analyzer in an ore microscope is measured, and can be turned 90 degrees for cross polarization at the extinction angle. Our ore microscopes have all the necessary features including a Bertrand lens, polarizer, analyzer, compensator plates, transmitted polarized light and reflected polarized light. We recommend you to contact our technical sales staff for answers to your questions about ore and polarized light microscopes.

Ore Microscopes .com has a good selection of ore polarized light microscopes for sale. These ore microscopes are great for geology and petrology studies as they are primarily used for rock and mineral identification and analysis. Thick polished specimens of rocks and minerals are viewed under these ore microscopes using plane and cross polarized light. The ore microscope differs from the normal polarizing microscope in that it has the added feature of using incident reflected polarized light on the specimen, allowing a thick opaque polished rock to be viewed in great detail. A standard polarized microscope only is capable of using transmitted polarized light on a transparent rock and mineral thin section. Ore microscopes is your source for the microscopes you need for examining, analyzing, and identifying rocks and minerals. Contact them today for more details about their optical microscopy items.

Polarizing Microscopes is your location for a huge variety of polarizing light microscopes. Features include plane polarized transmitted light and cross polarized transmitted light, complete with Bertrand lens and compensator plates such as quartz wedge, mica, and gypsum. They have both a polarizer and an analyzer that can be turned to the extinction angle to view rock and mineral thin sections under crossed polarization. These are great for mineral identification in geological laboratories and petrology departments. Whatever your needs are in polarized light microscopy, please give us a call to assist you with a solution.

Your best source for polarized light microscopes is Polarizing Microscopes .com. Visit us and see for yourself our wide variety of polarizing microscopes suitable for mineral identification in geology and petrology labs. Our petrographic microscopes come complete with Bertrand lens and compensator plates, and are ready to view rock and mineral thin sections under transmitted plan polarized light and transmitted cross polarized light. If a rock or mineral specimen is cut in a thin enough section, light will pass through it. These thin sections are placed under the polarizing microscope and transmitted polarized light is passed through them. Our low prices make owning one of these fine optical instruments affordable. Be sure to give us a call to discuss all of your polarized light microscopy needs.
