AmScope SM-4TZ-144A Professional Trinocular Stereo Zoom Microscope, WH10x Eyepieces, 3.5X-90X Magnification, 0.7X-4.5X Zoom Objective, Four-Zone LED Ring Light, Double-Arm Boom Stand, 110V-240V, Includes 0.5X and 2.0X Barlow Lens

Description

The AmScope SM-4TZ-144A professional trinocular stereo zoom microscope has a
pair of 10x super-widefield high-eyepoint eyepieces, a 0.7x-4.5x zoom
objective, two Barlow lenses, and a double-arm boom stand. The microscope has
an overall magnification range of 3.5x-90x. 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 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 0.5x and 2.0x Barlow lenses that
can be added to the objective to increase the magnification range. A Barlow
lens with a magnification of less than 1.0 reduces magnification and increases
the working distance, while 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 144-bulb LED ring light has four
separate zones to independently control light intensity and direction. The
ring light provides bright, cool light for working with temperature-sensitive
or live specimens, and shadow-free illumination. A rheostat controls the
amount of light emanating from the lamp. Power and adjustment controls are
located on a control box to speed adjustments. The ring has a 2-1/2″ (64mm)
inside diameter and a 4″ (100mm) outside diameter. It has a 100,000-hour life
span and a 110V-240V variable power supply. The microscope has a double-arm
boom stand that enables users to position the microscope head on all three
axes (X, Y, and Z). Bilateral focus eases use for left- and right-handed
users. The stand has 20″ double arms, and a 30″ overall length. The pillar is
17″ and the focus rack has a 3″ diameter. The solid cast-steel base is 2 x
8-1/4 x 10-1/4 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).SpecificationsHeadTrinocularMagnification range3.5x-90xZoom objective

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.United Scope manufactures microscopy equipment and
accessories under the brand name AmScope. The company, founded in 1996, is
headquartered in Irvine, CA.What’s in the Box?AmScope SM-4TZ-144A stereo zoom
