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.

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.
