The Am M500B-MS-LED cordless monocular compound micro
has interchangeable 10x widefield and 20x widefield eyepieces, a
forward-facing nosepiece with four DIN achromatic objectives, LED
illumination, coaxial separate coarse and fine focus, a 1.25 NA
Abbe condenser, and a plain stage with a mechanical specimen
holder. The monocular viewing head has a fixed 45-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, and 100xS (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-immersion objective uses oil between the specimen and the
objective lens to provide 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, and a rheostat controls the a of light emanating
from the lamp. 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 plain stage has clips to secure the specimen in place, and is
4-3/8 x 4-3/4 inches (110 x 120mm) (W x D; where W is width, the
horizontal distance from left to right; D is depth, the
horizontal distance from front to back). A mechanical specimen
holder can be added to the plain stage to provide precise
movement, perform measurements, and record coordinates. Separate
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. All the mechanical parts of the micro are constructed
of metal to provide durability and resistance to wear. The metal
frame has a stain-resistant enamel finish for durability and to
ease cleaning. The micro can be powered by a 110V wall
outlet or by three AA rechargeable batteries (included).
Batteries can be recharged using the included power
cord/recharger.

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.
