- Trinocular compound micro provides high magnification for biological use and educational applications.
- Trinocular viewing head with vertical camera and Siedentopf binocular with pairs of 10x widefield and 20x widefield eyepieces with 55 to 75mm interpupillary adjustment, fixed 30-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to provide a more comprehensive view and enable sharing.
- Reverse-ed ball-bearing driven nosepiece with 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic precision-ground optical-glass objectives that provide color correction of magnified images.
- Brightfield, halogen illumination with rheostat to control light intensity, and 1.25 NA Abbe condenser with iris diaphragm and rack-and-pinion focus control 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 T520B compound trinocular micro has a Siedentopf
binocular with interchangeable pairs of 10x widefield and
20x widefield eyepieces, a reverse-ed nosepiece with four
DIN 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 WF10x and WF20x eyepieces with 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 reverse-ed, ball-bearing driven nosepiece
has 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN
optical-glass achromatic objectives that combine with the
eyepieces to provide color correction of magnified images. 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 reverse-ed
nosepiece keeps objectives out of the way to prevent damage and
contamination, and to enable more secure slide handling. A
compound micro is used for inspection and dissection of
specimens when two-dimensional images are desired.
The micro has lower (transmitted, 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. Halogen
illumination provides bright light in a concentrated path and has
a rheostat to control light intensity. The 1.25 NA Abbe condenser
is ed on a rack-and-pinion control system, 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. A stage stop prevents the stage from coming into
contact with the slide and objectives. The stage is 5-1/2 x 5-1/2
inches (140 x 140mm) and has a traveling range of 2-15/16 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.
