- Digital trinocular compound micro provides high magnification for biological use and educational applications, and has a 3MP camera with reduction lens and USB 2.0 output for capturing or displaying images on a computer or projector.
- Sliding trinocular viewing head with pairs of 10x and 20x widefield achromatic eyepieces and sliding head to adjust interpupillary distance, fixed 45-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to provide a more comprehensive view and enable sharing.
- Forward-facing nosepiece with 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic objectives that provide color correction of magnified images.
- Brightfield halogen illumination 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 1.0mm stage divisions, locks 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.
The Am T390B-3M digital professional compound trinocular
micro interchangeable pairs of 10x and 20x widefield
eyepieces, a forward-facing nosepiece with four DIN achromatic
objectives, Brightfield halogen illumination, and a double-layer
mechanical stage. The 3MP camera has a CMOS color sensor, a
reduction lens, image capture and editing software, and USB 2.0
output to capture or display still or video images on a computer
or projector. The trinocular head has a sliding binocular
with an adjustable 55 to 75mm interpupillary distance, 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. 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
eight magnifications. 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 digital compound micro is used for inspection
and dissection of specimens when two-dimensional images are
desired, and where image capture, detailed records, or
documentation is required.
The 3MP digital camera has a CMOS color sensor for displaying
still microscopy images and streaming live videos to a computer
or projector. The camera has 40x magnification and a 0.5x
reduction lens that ensures that the display has a similar field
of view as the micro eyepiece. The camera can be ed in
a C- or any 23mm eye tube. The camera includes image capture
and editing software that provides still image and live video
capture and editing capability, including measurement functions.
The software supports JPG, TIF, GIF, PSD, WMF, and BMP file
formats and is compatible with Windows XP, Vista, 7, and 8; Mac
OS X; and Linux. Camera drivers are compatible with Windows XP,
Vista, 7, and 8; Mac OS X; and Linux. The software includes
Windows APIs for native C/C++, C#, DirectShow, Twain, and LabVIEW
that enable custom application development. The camera has a USB
2.0 data port (cable included).
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. 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. The stage is 5-1/2 x 5-1/2
inches (140 x 140mm) and has a traveling range of 3 x 2 inches
(75 x 50mm). Graduated coaxial coarse and fine focus enables
measurements to be taken. 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.
