The AmScope PZ200BB compound polarizing microscope has a Siedentopf binocular mount with interchangeable pairs of 10x widefield and 20x widefield eyepieces, a focusable Bertrand lens on a rotatable disc, a forward-facing nosepiece with three DIN strain-free plan achromatic objectives, polarizing and Brightfield halogen illumination, and a round graduated stage with a stage stop to protect slides and objectives from damage. The Siedentopf binocular mount has interchangeable pairs of WF10x and WF20x eyepieces with 55 to 75mm interpupillary adjustment, a fixed 45-degree vertical inclination to reduce eye and neck strain, and a 360-degree rotation capability to enable sharing. A Siedentopf binocular head enables the viewer to change the interpupillary distance without changing the tube length, eliminating the need to re-focus the image. Dioptric adjustment accommodates individual eye-strength differences. The forward-facing, ball-bearing driven triple nosepiece has 4x, 10x, and 40xS (spring) DIN strain-free plan achromatic objectives. Strain-free objectives are optimized for use with polarized light, and plan achromatic objectives provide color correction and focus over the entire viewing field. The 40xS objective is spring loaded to prevent slide damage when focusing. Polarizing microscopes are used in geology, petrology, mineralogy, toxicology, pharmacology, forensics, and industrial inspection applications to view and measure birefringence of anisotropic materials, including organic compounds, water, minerals, and rocks.The microscope has polarizing and Brightfield illumination with a selection knob to choose between illumination types. The built-in Bertrand lens has a rotating disc with centering controls, and 90-degree rotation with 1-degree graduations. The polarizer, analyzer, and Bertrand lens can be removed from the optical path to use the microscope as a Brightfield microscope. Transmitted 20W halogen illumination has a rheostat to
