The AmScope IN200TA-M digital inverted trinocular compound microscope has interchangeable pairs of 10x and 16x plan widefield eyepieces, an under-mounted quadruple nosepiece with four DIN long working-distance plan objectives, top-mounted Brightfield halogen illumination, a 1.25 NA condenser with iris diaphragm, and a double-layer mechanical stage with a stage stop to protect slides and objectives from damage. 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 anti-mold trinocular head has a sliding binocular mount with 55 to 75mm interpupillary adjustment and a fixed 30-degree vertical inclination to reduce eye and neck strain. Anti-mold coatings protect the microscope in high-humidity environments. Interchangeable pairs of WF10x plan and WF16x plan eyepieces provide improved focus over the entire field of view (FOV). Dioptric adjustment on both eyepieces accommodates individual eye-strength differences. The vertical trinocular port accepts a 23mm or C-Mount camera. The under-mounted nosepiece has 4x, 10x, 25x, and 40x (spring) DIN long working-distance plan achromatic objectives that combine with the eyepieces to provide color correction of magnified images. Long working-distance plan objectives provide improved focus over the entire range of the viewing field and a longer working distance that is required when viewing specimens in dishes and large containers. An inverted microscope has its light source above the stage pointing downward and the objectives and turret below the stage pointing upward. It is most often used for observing organisms in a large container, such as a well plate or petri dish. It can also be used when specimens require manipulation, or in metallurgical applications.
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 microscope eyepiece. The camera can be mounted in a C-Mount 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).
Brightfield illumination is mounted above the stage and has a traveling range of 25/32" (20mm). Transmitted 20W halogen illumination has a rheostat to control light intensity, and provides bright light in a concentrated path. The 1.25 NA condenser has two swing-out color filter holders, and is mounted on a steel rack-and-pinion control system that can be adjusted to control the distance of the light from the stage. An iris diaphragm optimizes the amount of light illuminating the specimen. The double-layer mechanical stage with 1mm stage divisions and 0.1mm vernier resolution 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 oversize stage is 7-1/2 x 5-11/16 inches (190 x 145mm) (W x D) and has a traveling range of 3 x 2 inches (75 x 50mm) (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 has a focusing range of 1-9/16" (40mm), tension-adjustable coarse focusing, and an adjustable lock ring stopper that limits stage range to protect slides and objectives from damage. All-metal mechanical parts, solid-metal frame construction, and a stain-resistant enamel finish provide durability.

Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes 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. Microscopes 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. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.
