Polarizing microscopes [ http://www.polarizingmicroscopes.com ]
N/A
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. - [Read more] |
Ore microscopes [ http://www.oremicroscopes.com ]

Ore Microscopes .com 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. - [Read more] |
