The Am B120C compound binocular micro has pairs of 10x
widefield and 25x widefield eyepieces, a forward-facing nosepiece
with four DIN achromatic objectives, Brightfield (BF) LED
illumination, a 1.25 NA Abbe condenser, and a double-layer
mechanical stage.The Siedentopf binocular head has
interchangeable pairs of 10x widefield and 25x widefield
eyepieces with 53 to 77mm Siedentopf inter-pupillary adjustment,
a fixed 30-degree vertical inclination to reduce eye and neck
strain, and a 360-degree rotation capability to provide a more
comprehensive view and enable sharing. Dioptric adjustment
accommodates individual eye-strength differences. The
forward-facing nosepiece has 4x, 10x, 40xS (spring), and 100xS
(spring, oil) DIN achromatic objectives that combine with the
eyepieces to provide color correction of magnified images at five
magnifications. The 40xS objective is spring loaded to prevent
slide damage when focusing. The 100xS spring-loaded oil objective
provides increased resolution over a standard objective. A
compound micro is used for inspection and dissection of
specimens when two-dimensional images are desired.
The micro has lower (diascopic) Brightfield illumination
that transmits light up through the specimen for enhanced
visibility of translucent and transparent objects. Brightfield
(BF) illumination allows the specimen to absorb light, resulting
in a dark image on a light background. LED illumination provides
bright, cool light for working with temperature-sensitive or live
specimens. The 1.25 NA Abbe condenser can be adjusted to control
the distance of the light from the stage and has an iris
diaphragm to optimize the a of light illuminating the
specimen. The double-layer mechanical stage, with 1mm stage
divisions, locks the slide into place and provides precise slide
manipulation along the X- and Y-axis to allow coordinates to be
recorded, enabling the viewer to return to a specific location on
the slide. Separate coarse and fine focus knobs speed focusing.
The enamel-coated cast-steel body is durable and resistant to
stains and corrosion.

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.
United manufactures microscopy equipment and accessories
under the brand name Am. The company, founded in 1996, is
headquartered in Irvine, CA.
