Whitney Polarizing Microscope
The Whitney polarizing microscope is available with transmitted light only or reflected and transmitted light. This polarizing microscope comes standard with a Bertrand lens, polarizer, analyzer, Gypsum full λ wave plate, Mica 1/4 λ wave plate and Quartz wedge. The stage rotates 360° and can be locked into position. An optional mechanical stage provides moving range of 30mm x 40mm with high precision micrometer. Infinity corrected strain free objective lenses provide crisp and clear images.
