The AmScope ME320T-PZ polarizing metallurgical trinocular microscope has a pair of 10x widefield eyepieces, a
forward-facing triple nosepiece with three DIN plan achromatic metallurgical objectives, 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 Siedentopf 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 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
forward-facing triple nosepiece has 4x, 10x, and 50xS (spring) plan achromatic metallurgical 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. The 50xS objective is spring loaded to prevent slide damage when focusing. A
polarizing metallurgical microscope uses transmitted and reflected light and a polarizing filter to view metallurgical
specimens, including electronics, or larger specimens not viewable on a standard microscope stage.
The 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 rheostat-controlled 30W 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 7 x 5-3/4 inches (180 x 145mm)
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).

Microscopes are instruments used to enhance the resolution of an object or image. 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, fluorescent, and mirror light sources to help control viewing
capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry,
manufacturing, and in the medical, forensic science, and veterinary industries.
United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The company, founded in
1996, is headquartered in Irvine, CA.
