The Am T690B-PL compound trinocular micro has a
Siedentopf binocular with interchangeable pairs of 10x
super-widefield and 20x super-widefield eyepieces, a
reverse-ed nosepiece with four DIN infinity plan achromatic
objectives, Brightfield halogen illumination, and a double-layer
mechanical stage with a stage stop to protect slides and
objectives from damage. The trinocular head has a vertical camera
and a Siedentopf binocular with interchangeable pairs
of WH10x and WH20x eyepieces, 55 to 75mm Siedentopf
interpupillary 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 vertical trinocular port accepts a camera with a
23mm or C- adapter (camera sold separately). The mechanical
tube length is 6-5/16" (160mm). The reverse-ed revolving
nosepiece has 4x, 10x, 40xS, and 100xS (oil) DIN infinity plan
achromatic objectives that provide color correction, focus over
the entire range of the viewing field, and a longer working
distance for improved focus when auxiliary components are
utilized. The 40xS objective is spring loaded to prevent slide
damage when focusing. The 100xS spring-loaded oil-immersion
objective uses oil between the specimen and the objective lens to
provide 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 Brightfield (BF) illumination which allows the
specimen to absorb light, resulting in a dark image on a light
background. Halogen light source provides bright light in a
concentrated path, and a Kohler condenser focuses and centers the
light path using two iris diaphragms, providing optimum contrast
and resolution. The graduated 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. A stage stop prevents the stage
or specimen from coming into contact with the objectives. The
stage is 7.1 x 5.9 inches (180 x 150mm) and a traveling range of
3 x 2 inches (75 x 50mm). Graduated coaxial coarse and fine focus
has a focusing range of 1-3/16" (30mm) and fine-focus divisions
of 0.002mm (0.0000787") that enable measurements to be taken.
Focus knob tension control prevents the stage from drifting out
of focus. The cast-alloy enamel-coated 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.
