The AmScope ME1200TB inverted metallurgical trinocular microscope has interchangeable pairs of 10x18mm and 20x10mm plan widefield eyepieces, a quadruple nosepiece with four DIN plan achromatic objectives, episcopic Brightfield and polarizing LED illumination, a polarizing condenser, and a double-layer mechanical stage with a stage stop to protect slides and objectives from damage. The trinocular viewing head has a vertical camera mount, a Siedentopf binocular head to adjust interpupillary distance, and a fixed 45-degree vertical inclination to reduce eye and neck strain. The vertical trinocular port has a 100% light-splitting rate and can be used as a 23mm photo port (camera sold separately). The Siedentopf head has a range of 55 to 75mm to accommodate individual eye differences, and bilateral dioptric adjustment to accommodate individual eye-strength differences. 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. The microscope has a forward-facing quadruple nosepiece and includes 5x, 10x, 20x, and 50x DIN plan achromatic objectives that combine with the eyepieces to provide color correction of magnified images. Plan objectives provide improved focus over the entire range of the viewing field. A metallurgical microscope uses transmitted and reflected light to view opaque or metallic specimens, or larger specimens that cannot be viewed on a standard microscope stage.

The microscope has reflected and transmitted episcopic Brightfield and polarizing illumination. Polarizing illumination reflects light off the specimen for enhanced visibility of opaque specimens. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background. The episcopic illumination system has independent filter holders for yellow, blue, and green filters (included). The iris diaphragm provides optimum contras
