- Brightfield and phase-contrast, halogen illumination with rheostat to control light intensity, and Kohler condenser with two iris diaphragms for precise focus, clear examination, and light control.
- Double-layer mechanical stage with 1mm stage divisions and stage stop; graduated coarse and fine focus with tension control to prevent stage drift.
The Am T690A-PCT200-PL compound trinocular micro has a
Siedentopf binocular with interchangeable pairs of 10x
super-widefield and 15x super-widefield eyepieces, a
reverse-ed nosepiece with four DIN infinity plan achromatic
objectives, four turret-ed phase-contrast 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 WH15x 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. Four plan phase-contrast objectives
(10x, 20x, 40x, and 100x) and corresponding condensers provide
high-contrast images. Plan objectives provide improved focus over
the entire range of the viewing field. The turret eases
magnification changes. A compound micro is used for
inspection and dissection of specimens when two-dimensional
images are desired.
The micro has Brightfield and phase-contrast illumination.
Brightfield (BF) illumination allows the specimen to absorb
light, resulting in a dark image on a light background.
Phase-contrast provides high contrast and visibility without the
use of stains, allowing specimens to be observed in their natural
state without being killed or fixed. 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
