Am SW-3T24Z Trinocular Stereo Micro, WH10x Eyepieces, 20X/40X/80X Magnification, 2X/4X Objective, Single-Arm Boom Stand, Includes 2.0x Barlow Lens

The Am SW-3T24Z trinocular stereo micro head has a 2x/4x objective, a pair of 10x20mm widefield high-eyepoint eyepieces, a 2.0x Barlow lens, and a single-arm boom stand. The micro head has a 3" O-ring style ing ring. The trinocular viewing head has an interpupillary range of 47 to 75mm, a 45-degree inclination to reduce eye and neck strain, and 360-degree rotation to enable sharing. The vertical trinocular port can be used as a C- or 23mm photo port (camera sold separately). The WF10x20mm super-widefield high-eyepoint eyepieces combine with the 2x/4x objective to provide 20x, 40x, and 80x magnification, and a longer working distance for inspecting large-scale specimens that require handling or repair. The micro includes 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, dioptric adjustment accommodates individual eye-strength differences, and eye guards ensure comfortable viewing. The optical glass lenses provide sharp images, and are fully-coated to ensure high-resolution images. A stereo micro, sometimes called an inspection or dissection micro, 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 micro has a 17" pillar that has an 8" vertical working distance. The 16" single-arm boom has a 24" overall length. Bilateral focus eases use for left- and right-handed users. The micro head can be rotated on the X- and Y-axis. The solid cast-steel base is 1-3/4 x 9 x 9 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).

Types include compound, stereo, or digital. Compound micros use a compound optical system with an objective lens and an eyepiece. Stereo micros show object depth in a three-dimensional image. Digital micros are used to display an image on a monitor, rather than looking through a lens. Micros 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. Micros 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. Micros are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries. United manufactures microscopy equipment and accessories under the brand name Am. The company, founded in 1996, is headquartered in Irvine, CA.
