The AmScope B120B-E2 compound binocular microscope has pairs of 10x widefield and 20x widefield eyepieces, a forward-facing nosepiece with four DIN achromatic objectives, Brightfield (BF) LED illumination, a 1.25 NA Abbe condenser, and a double-layer mechanical stage. The integrated 2MP CMOS sensor has a removable USB 2.0 output to capture or display still or video images on a computer or projector. The Siedentopf binocular head has interchangeable pairs of 10x widefield and 20x widefield eyepieces with 53to 77mm Siedentopf inter-pupillary adjustment, 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 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 objective provides increased resolution over a standard objective. A digital compound microscope is used for inspection and dissection specimens when two-dimensional images are desired, and where image capture, detailed records, or documentation is required.
The microscope includes a 2MP camera that has a CMOS color sensor for displaying still and video images, or streaming live video to a computer or projector. The camera is compatible with Windows, Mac OS X, and Linux. The camera includes a Windows-only compatible image capture and editing software package that provides still image and live video capture and editing. The software supports JPG, TIF, GIF, PSD, WMF, and BMP file formats. Editing features include stitching, EDF (extended depth of field), note insertion, and adding shapes and watermarks.
The microscope 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 amount 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. Separate coarse and fine focus knobs speed focusing. The enamel-coated cast-steel body is durable and resistant to stains and corrosion.

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.
