Product Description

The Thomas PX4302A101T Trinocular Stereo Zoom Microscope has a pair of 10x widefield eyepieces, a trinocular port, a 1x to 4x zoom objective for 10x to 40x continuous magnification, Greenough optical system, upper halogen and lower fluorescent illumination, interchangeable stage plates, coaxial focus, and a fixed stage. The trinocular viewing head has a binocular head with a pair of eyepieces with interpupillary adjustment, fixed inclination to reduce eye and neck strain, and 360-degree rotation capability to provide a more comprehensive view and enable sharing; and a trinocular port that accepts a camera adapter (sold separately). Dioptric adjustment accommodates individual eye-strength differences. The zoom objective provides low magnification and a longer focal length for inspecting large-scale specimens, or specimens that require hands-on manipulation or repair, including rocks, minerals, watches, or circuit boards. Click stops at 10x, 20x, 30x, and 40x magnification ensure accurate positioning for repeatable results. The Greenough optical system provides precision image creation. A stereo zoom microscope is used for inspection and dissection of specimens when three-dimensional images are desired, and provides zoom, sometimes called pancratic, magnification that allows the user to zoom in on the specimen within a continuous magnification range.

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 upper halogen light source provides bright light in a concentrated path. The lower fluorescent light source provides cool, white light for observing specimens as they would appear in their natural environment. A rheostat controls the amount of light emanating from the lamps. The black and white stage plates are used with top-mounted lighting to provide contrast with light- and dark-colored specimens. The frosted glass stage plate provides evenly diffused illumination. The fixed stage has stage clips to secure the slide or specimen in place while viewing. Coaxial focus eases focusing for left- and right-handed viewers, and a slip clutch prevents excess pressure from damaging the slides or objectives.

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.
