- Compound micro provides high magnification for biological use and educational applications.
- Monocular viewing head with interchangeable 23mm 10x widefield and 20x widefield eyepieces, fixed 30-degree vertical inclination to reduce eye and neck strain, 360-degree rotation capability to enable sharing, and anti-mold head to preserves optics in high-humidity area.
- Forward-facing nosepiece with precision-ground 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic glass objectives provide color correction of magnified images.
- Brightfield imaging with rheostat-controlled LED illumination and spiral-control 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 and stage stop, and graduated coarse and fine focus with tension control to prevent stage drift.
The Am M620B monocular compound micro has
interchangeable 10x widefield and 20x widefield eyepieces, a
forward-facing nosepiece with four DIN achromatic objectives, LED
illumination, coaxial nested coarse and fine focus, a 1.25 NA
Abbe condenser, and a double-layer mechanical stage. The
monocular viewing head has a fixed 30-degree vertical inclination
to reduce eye and neck strain, and 360-degree rotation capability
to enable sharing. An anti-mold head preserves optics in
high-humidity areas. The forward-facing revolving nosepiece has
4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic
objectives that provide color correction of magnified images. The
40xS and 100x S objectives are spring loaded to prevent damage to
the slide or objective when focusing. The 100xS oil objective
provides increased resolution over a standard objective. The
fully-coated optical system provides sharp, high-resolution
images. A compound micro is used for inspection and
dissection of specimens when two-dimensional images are desired.
The micro has lower (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. LED illumination provides
bright, cool light for working with temperature-sensitive or live
specimens. The 1.25 NA Abbe condenser 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 condenser is controlled using a spiral mechanism.
The mechanical stage has 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. It has a
traveling range of 2-13/16 x 1-3/16 inches, and is 4-5/8 x 5
inches (118 x 127mm) (W x D; where W is width, the horizontal
distance from left to right; D is depth, the horizontal distance
from front to back). Nested coaxial coarse and fine focus eases
focusing for left- and right-handed viewers, and a
rack-and-pinion mechanism provides precise and secure focusing.
Focus tension control prevents stage drift. The metal frame has a
stain-resistant enamel finish for durability and to ease
cleaning.

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.
