The O.C. White TKSZ-D Prolite 4.5 Binocular Stereo Zoom Microscope has a pair of 10x eyepieces, a 0.7x to 4.5x zoom objective and 0.5 auxiliary objective for 3.5x to 45x continuous magnification, dual-point halogen illumination, and a ball-bearing base. The binocular viewing head has a pair of eyepieces with fixed inclination to reduce eye and neck strain, and rotation capability to provide a more comprehensive view and enable sharing. 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. 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 a dual-point fiber optic illuminator with gooseneck arms that flex to direct light where needed. A halogen light source on each arm provides bright light in a concentrated path. The base has a double ball-bearing arm for secure positioning and is weighted for stability.

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. O.C. White manufactures lighting fixtures for medical, scientific, and fabrication applications. The company, founded in 1894, is headquartered in Thorndike, MA. What's in the Box?O.C.
