The Am B490B-M digital compound binocular micro has a
sliding head, interchangeable pairs of 10x widefield and 20x
widefield eyepieces, a forward-facing nosepiece with four DIN
achromatic objectives, Brightfield halogen illumination, a
double-layer mechanical stage with a stage stop to protect slides
and objectives from damage, and anti-mold surfaces to preserve
optics in high-humidity areas. The 1.3MP 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 compensation-free binocular viewing
head has interchangeable pairs of 10x widefield and 20x widefield
eyepieces and sliding head to adjust inter-pupillary 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. The sliding head has a
range of 55 to 75mm to accommodate individual eye differences,
and bi-lateral dioptric adjustment accommodates individual
eye-strength differences. The forward-facing nosepiece has 4x,
10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic
optical-glass 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 objective provides 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 1.3MP 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 0.37x
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 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 2-15/16 x 1-3/4
inches (75 x 45mm). 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 solid-metal 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.
This is a professional binocular micro with 1.3MP high
quality digital camera. It is designed for teaching
demonstration, clinical examination and research purpose. It
comes with a 30 degree inclined 360 degree swiveling compensation
free binocular head, 3D mechanical stage and an
intensity-variable halogen illumination system. This micro
offers eight levels of magnification, 40X, 80X, 100X, 200X, 400X,
800X, 1000X & 2000X.
The digital camera captures still images and video, and allows
you to view a live stream on your PC. With software available for
Windows, Mac, and Linux, it's a multi-platform imaging solution.
The included Windows software offers image-development and
measurement tools, as well as advanced compositing features such
as image-st and extended-depth-of-focus. Independent
preview and capture resolutions allow you to view high-speed
video while capturing high-definition images. For Mac and Linux,
there is a lite version with limited processing features.
