- Professional stereo microscope with track stand has long working distance to enable users to perform work or manipulate large items, including inspection of biological specimens
- Binocular viewing head with pair of 10x extreme-widefield eyepieces, adjustable interpupillary distance, fixed 45-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to enable sharing
- 0.67x-4.5x zoom objective provides continuous zoom magnification and longer focal length for inspecting large-scale specimens, and a 2.0x Barlow lens extends the magnification range
- 15W halogen light source can be used above or below the specimen, frosted stage plate allows light to pass through from below with transparent specimens, and reversible black and white stage plate provides contrast with light- and dark-colored specimens

The AmScope ZM-2BY-EB professional binocular stereo zoom microscope has a pair of 10x extreme-widefield high-eyepoint eyepieces, a 0.67x-4.5x zoom objective, a 2.0x Barlow lens, and a track stand. The microscope has an overall magnification range of 6.7x-90x. The binocular viewing head has an interpupillary range of 55 to 75mm, a 45-degree inclination to reduce eye and neck strain, and 360-degree rotation to enable sharing. The EW10x22mm extreme-widefield high-eyepoint eyepieces combine with the 0.67x-4.5x zoom objective to provide zoom magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. The microscope comes with a 2.0x Barlow lens that can be added to the objective to increase the magnification range. A Barlow lens with a magnification greater than 1.0 increases the magnification and reduces the working distance. High-eyepoint eyepieces ease viewing for users who wear glasses, and dioptric adjustment accommodates individual eye-strength differences. A stereo microscope, sometimes called an inspection or dissection microscope, has low magnification and a long working distance that enables users to manipulate the object being inspected.
The microscope has upper (episcopic) illumination that reflects light off the specimen for enhanced visibility of opaque specimens, and lower (diascopic) illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. The 15W halogen light source can be mounted above the specimen on an articulating arm to control light direction, and below the specimen, and a rheostat controls the amount of light emanating from the lamp. When mounted below the specimen, the light is directed using a mirror, providing bright light with minimal temperature change when used with temperature-sensitive or live specimens. A frosted stage plate allows light to pass through from below with transparent specimens, a reversible black and white stage plate provides contrast with light- and dark-colored specimens, and stage clips secure the specimen during viewing. The 15W halogen light source provides bright light in a concentrated path. The pillar-style stand has bilateral coarse focus to ease use for left- and right-handed users. All metal construction is durable and the enamel finish is stain-resistant.

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.
