Nikon Optiphot polarizing microscope with bright field and polarizing optics. It has 5 objectives 4, 10, 20, 40 and 100X. The 20X is an apochromat. It has a mechanical stage to move glass slides, 2 - 10X wide field eyepieces. It has a trinoculor head for attaching a camera, 2 rotating polarizers and a full wave retardation plate. The condenser has some dirt inside but its not visible if the condenser is lowered slightly. It has a built in light source.

Ideal for a geologist, university student, forensic scientist, biologist, veterinarian or artist. It's setup for demonstration in my home in Calgary, NW. I can offer basic training. Similar microscopes on E-bay cost about $5,000. I include a printed instruction manual, microscope cover. I own own another Nikon Optiphot microscope which I I use for Fluorescence microscopy I have extensive experience with microscopes. To learn more about microscopy see my web site: www.canadiannaturephotographer.com. I also offer workshops on microscopy. I have attached some pictures below (crystals, water bear, wood section) viewed by polarized light microscopy. This microscope can also be used as a basic bright field microscope for viewing histology slides, microorganisms, insects and other specimens. (I am selling it because I own other polarizing microscopes that I use regularly.
