AmScope ME1200TB Inverted Trinocular Metallurgical Microscope, 50X-1000X Magnification, PL10x and PL20x Eyepieces, Polarizing Condenser, Brightfield and Polarizing LED Illumination with Rheostat, Large Double-Layer Mechanical Stage, 90-240V

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 contrast and resolution. The 3W LED light source provides bright, cool light for working with temperature-sensitive or live specimens, and a rheostat controls the amount of light emanating from the lamp. The double-layer mechanical stage has a 0.001mm vernier graduation and a removable stage plate to provide transmitted illumination. A vertical stage stop prevents the stage from coming into contact with the slide and objectives. The stage is 7-3/32 x 6-1/8 inches (180 x 155mm) and has a traveling range of 3 x 1-9/16 inches (75 x 40mm). The microscope has a focusing range of 1-5/16" (33mm) and a mechanical tube length of 6-5/16" (160mm). Coaxial coarse and fine focus has tension control to prevent the stage from drifting out of focus. The enamel-coated cast-steel body is durable and resistant to stains and corrosion.

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.
