The Bresser Science MTL 201 is a special reflected light microscope, which allows to observe non-transparent surfaces at higher magnifications (50x-800x). This solid designed instrument is ideal for working in metallography (e. g. microscopy of polished samples of metals or alloys), mineralogy, precision engineering and electronics. It is suitable for scientific research, teaching demonstration and industrial production (e.g. quality controlling). According to its purposes, the MTL 201 is equipped with a large stage (250 mm x 230 mm), which can be moved coarsely by a quick adjustment lever and finely by a transverse and a longitudinal knob. The focuser has coarse and fine drive (coaxial; circa 70 µm/ full turn). The illumination is done by a halogen lamp (20 W) with a dimmer. The light comes through the objective from above onto the sample. There are a field diaphragm, which can be centered, some filters (yellow, green, blue, ground glass) and a polarizer/analyzer combination. The fivefold nosepiece is equipped with planachromatic DIN objectives (5x, 10x, 20x, 40x, 80x). The trinocular head bears two 30° inclined ocular tubes and the photo tube. The oculars (with 10x wide field lenses) have diopter and eye relief adjustments. The photo tube allows for digital imaging, e. g. with an optional available PC eyepiece. Further optional accessories: Eyepiece (WF16x), dividing eyepiece (WF10x), planachromatic objective (50x).
