AmScope AmScope ZM-4BN Professional Binocular Stereo Zoom Microscope, EW10x Focusing Eyepieces, 6.7X-45X Magnification, 0.67X-4.5X Zoom Objective, Ambient Lighting, Double-Arm Boom Stand

The AmScope ZM-4BN professional binocular stereo zoom microscope has a pair of 10x extreme-widefield focusing high-eyepoint eyepieces, a 0.67x-4.5x zoom objective, and a double-arm boom stand. The microscope has an ove...rall magnification range of 6.7x-45x. 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 focusing 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. Focusing eyepieces provide fine focus, 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.

Ambient lighting illuminates the specimen, eliminating the need for power or batteries. The microscope has a double-arm boom stand that enables users to position the microscope head on all three axes (X, Y, and Z). The stand has 20" double arms, and a 30" overall length. Bilateral focus eases use for left- and right-handed users. The pillar is 17" and the focus rack has a 3" diameter. The solid cast-steel base is 2 x 8-1/4 x 10-1/4 inches (H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back).

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.

The VanGuard 1100ZL Series Stereo Zoom Microscopes with either a binocular or trinocular head have a 360-degree rotation capabilit...y and a fixed 45-degree vertical inclination to ease eye strain, -5 to +5 dioptric adjustment capabilities to compensate for the difference in viewing ability between each eye, and 55 to 90mm interpupiliary adjustment for individual eye spacing. The models in this series have 20mm 10x super widefield eyepieces, lens objectives of 0.7x to 4.5x, a zoom ratio of 6.5:1, and a working distance of 93 mm. The stage plate is reversible black and white for viewing light or dark samples, and the microscope has two, locked on, stainless steel, spring-loaded stage clips for durability. The units come with either a pole stand (100 mm vertical travel) or boom stand (300 mm vertical travel x 415 mm horizontal travel). They have dual focus adjustment knobs, for controlled focusing. These microscopes have a rack and pinion assembly, a slip clutch mechanism, and a tension control mechanism to protect the gears. The trinocular head model can be connected to a camera for an alternative viewing option. They are stain-resistant and have a durable cast metal body with an enamel finish, and anti-skid rubber feet. These models come with a spare fuse, two eyecups, a dust cover, and instructions. Additional optional eyepieces, lenses, lighting, and camera packages are sold separately.
