AmScope SM-3TYY-54S Professional Trinocular Stereo Zoom Microscope, WH10x and WH20x Eyepieces, 7X-180X Magnification, 0.

AmScope SM-3TYY-54S Professional Trinocular Stereo Zoom Microscope, WH10x and WH20x Eyepieces, 7X-180X Magnification, 0.

The AmScope SM-3TYY-54S professional stereo zoom microscope has interchangeable pairs of 10x and 20x super-widefield high-eyepoint eyepieces, a 0.7x-4.5x zoom objective, a 2.0x Barlow lens, and a single-arm boom stand. The microscope has an overall magnification range of 7x-180x. The trinocular 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 vertical trinocular port can be used as a C-Mount or 23mm photo port (camera sold separately). The WH10x20mm and WH20x10mm super-widefield high-eyepoint eyepieces combine with the 0.7x-4.5x zoom objective to provide continuous zoom magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. The microscope comes with 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, 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. The removable 54-bulb LED ring light provides bright, cool light for working with temperature-sensitive or live specimens. The ring light provides shadow-free illumination, and a rheostat controls the amount of light emanating from the lamp. Power and adjustment controls are located on the light head. The light uses a 110V-240V variable power supply. The microscope 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 microscope head can be rotated on the X- and Y-axes. 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 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 mir
