Aven 26800B-391 SSZ-30 Stereo Zoom Microscope with Stand DP2/CR, 7x-30x Magnification

The Aven SSZ and SPZ Series Stereo Zoom Microscopes with Stand come with a choice of 7.2 or +5.6 to -7.2 dioptric adjustment capabilities on both eyepieces to compensate for different viewing between each eye and 52 to 75 mm interpupiliary adjustment for individual eye spacing; a 10x widefield eyepiece either field number 23 or field number 20 (FN23 or FN20); 6.7x to 50x or 7x to 30x magnification; zoom ratio of either 7.46:1 or 4.3:1; and a working distance of either 97 mm or 108mm. These instruments have a choice of no illumination, long-lasting upper/lower LED illumination, or 9W fluorescent illumination to keep samples cool, with dimmers for control and a field view of either 34.3 to 3.5mm or 28.6mm at 7X, and 6.7mm at 30X (depending on the model). These microscopes have a choice of no stage plate for large samples, black/white reversible plate to view light or dark samples, or frosted glass plate and a black/white reversible plate to view light or dark samples. The stand for these units is a double arm boom stand, a column stand, or a pole stand. Models 26800B-370, 26800B-371, and 26800B-372 come with a dust cover, rubber eye guards, and a tension control pin. Models 26800B-391, 26800B-392, and 26800B-393 come with a dust cover, power supply, and stage plate. Additional auxiliary lenses and eyepieces are sold separately. Stereo microscopes create three-dimensional images and are used for education, biological sciences, and manufacturing applications, among others.

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.
