- Professional stereo micro with boom stand has long working distance to enable users to perform work or manipulate large items, including circuit boards and dental appliances.
- Trinocular viewing head with pairs of 10x and 20x super-widefield eyepieces, adjustable interpupillary distance, fixed 45-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to enable sharing.
- 0.7x-4.5x zoom objective provides continuous zoom magnification and longer focal length for inspecting large-scale specimens, and a 2.0x Barlow lens extends the magnification range.
- Removable rheostat-controlled 144-bulb LED has four separate zones to independently control light intensity and direction.
- Double-arm boom stand has 20" arms and 17" pillar to enable users to position the micro head on three axes (X, Y, and Z).
The Am SM-4TYY-144A professional trinocular stereo zoom
micro has interchangeable pair of 10x and 20x
super-widefield high-eyepoint eyepieces, a 0.7x-4.5x zoom
objective, a 2.0x Barlow lens, and a double-arm boom stand. The
micro 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- 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 micro 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 micro, sometimes called an inspection
or dissection micro, 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 a 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
micro has a double-arm boom stand that enables users to
position the micro 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).

Micros are instruments used to enhance the resolution of an
object or image. Types include compound, stereo, or digital.
Compound micros use a compound optical system with an
objective lens and an eyepiece. Stereo micros show object
depth in a three-dimensional image. Digital micros are used
to display an image on a monitor, rather than looking through a
lens. Micros 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. Micros 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. Micros are widely used in education,
lab research, biology, metallurgy, engineering, chemistry,
manufacturing, and in the medical, forensic science, and
veterinary industries.
