The Am M200-LED cordless monocular compound micro has a 10x widefield eyepiece, a forward-facing nosepiece with three DIN achromatic objectives, LED illumination, coaxial coarse and fine focus, a 0.65 NA single-lens condenser, and a plain stage. 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. The forward-facing revolving nosepiece has 4x, 10x, and 40xS DIN achromatic objectives that provide color correction of magnified images. The 40xS objective is spring loaded to prevent damage to the slide or objective when focusing. 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 0.65 NA single-lens condenser and disc diaphragm optimize the a of light illuminating the specimen. The plain stage is 4-3/8 x 4-3/4 inches (W x D; where W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back). It has an opening for light transmission, stage clips to secure the slide or specimen in place while viewing, and an upper stage stop to prevent the stage or specimen from coming into contact with the objectives. 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. All the mechanical parts of the micro are constructed of metal to provide durability and resistance to wear. The cast-alloy metal frame has a stain-resistant enamel finish for durability and to ease cleaning. The micro can be powered by 110V power supply or three AA batteries (included).

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.
