The AmScope M200A-PZ monocular compound microscope has interchangeable 10x widefield and 16x widefield eyepieces, a forward-facing nosepiece with three DIN achromatic objectives, tungsten illumination, Brightfield and polarizing imaging, coaxial coarse and fine focus, a 0.65 NA single-lens condenser, and a plain stage. The monocular viewing head has a fixed 45-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to enable sharing. The forward-facing revolving nosepiece has 4x, 10x, and 40xS DIN achromatic objectives that provide color correction of magnified images. The 40xS objective is spring loaded to prevent damage to the slide or objective when focusing. A compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired.

The microscope has lower (diascopic) polarizing and Brightfield imaging that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background. Tungsten (incandescent) illumination provides bright light, and a rheostat controls the amount of light emanating from the lamp. The 0.65 NA single-lens condenser and disc diaphragm optimize the amount of light illuminating the specimen. The plain stage is 4-3/8 x 4-3/4 inches (W x D; where W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back). It has an opening for light transmission, stage clips to secure the slide or specimen in place while viewing, and an upper stage stop to prevent the stage or specimen from coming into contact with the objectives. The polarizing kit includes a rectangular plate with a round stage, and a polarizing filter. The 4-4/8 x 4 inch (100 x 65mm) (W x D) rectangular plate has a 2-3/4" (70mm) diameter round stage. The stage has a 5/16" (8mm) observation
