- 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 pair of 10x 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, a 0.5x Barlow lens extends the working distance, 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-4TZ-144A professional trinocular stereo zoom
micro 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 micro 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- 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 micro 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
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.
