Description
- Metallurgical microscope uses transmitted and reflected light to view metallic specimens, including electronics, or larger specimens not viewable on a standard microscope stage
- Trinocular head with interchangeable pairs of 10x widefield and 16x widefield eyepieces and sliding head with 55 to 75mm interpupillary adjustment, fixed 30-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to enable sharing
- Forward-facing quadruple nosepiece with 4x, 10x, 40xS, and 100xS (oil) DIN plan optical-glass objectives that provide improved focus over the entire field of view
- Episcopic (reflected) illumination system has 20W halogen illumination with rheostat to control light intensity
- Double-layer mechanical stage has 1mm stage divisions with 0.1mm vernier graduations and stage stop; graduated coarse and fine focus with tension control to prevent stage drift
The AmScope ME300TZA metallurgical trinocular microscope has interchangeable pairs of 10x widefield and 16x widefield eyepieces, a forward-facing quadruple nosepiece with four DIN achromatic objectives, Brightfield episcopic halogen illumination, and a double-layer mechanical stage with a stage stop to protect slides and objectives from damage. The trinocular viewing head has a 23mm vertical camera mount, a sliding binocular head to adjust interpupillary distance, a fixed 30-degree vertical inclination to reduce eye and neck strain, and a 360-degree rotation capability to enable sharing. The sliding head has a range of 55 to 75mm to accommodate individual eye differences, and bilateral dioptric adjustment to accommodate individual eye-strength differences. The forward-facing nosepiece has 4x, 10x, 40xS (spring), and 100xS (oil) DIN plan optical-glass objectives that combine with the eyepieces to provide color correction of magnified images. The 40xS objective is spring loaded to prevent slide damage when focusing. The 100xS spring-loaded oil-immersion objective uses oil between the specimen and the objective lens to provide increased resolution over a standard objective. 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.\nThe microscope has reflected episcopic (upper) illumination that reflects light off the specimen for enhanced visibility of opaque specimens. The episcopic illumination system has independent filter holders for yellow, blue, green, and frosted filters (included). The iris diaphragm has separate aperture and alignment controls to provide precision lighting control. The 20W halogen light source provides bright light in a concentrated path and has a rheostat to control light intensity. The double-layer mechanical stage, with 1mm stage divisions and 0.1mm vernier graduations, locks the slide into place and provides precise slide manipulation along the X- and Y-axis to allow coordinates to be recorded, enabling the viewer to return to a specific location on the slide. A stage stop prevents the stage from coming into contact with the slide and objectives. The stage is 5-1/8 x 4-13/16 inches (130 x 122mm) and has a traveling range of 1-3/16 x 2-3/4 inches (30 x 70mm). Graduated coaxial coarse and fine focus has a focusing range of 1-9/16\" (40mm). Focus knob tension control prevents the stage from drifting out of focus. The microscope has a mechanical tube length of 6-5/16\" (160mm). The enamel-coated cast-steel body is durable and resistant to stains and corrosion.

Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluore
