The Ken-A-Vision 7890UM Vision Viewer is a digital, manual-focus document camera that captures and transmits still images and video to a television, computer, projector, or video recording device for classroom viewing using the attached USB cable. The CMOS camera sensor has a 1.3 mega-pixel (MP), 1280 x 1024 pixel resolution, and 720P high-definition (HD) video output at up to 30 frames-per-second (FPS). The gooseneck flexes 360 x 180 degrees for custom positioning. The camera displays microscope images using the included 28mm microscope eyepiece adapter. An 11.5 x 7.5 inch field of view has a 60-degree diagonal and 50-degree horizontal viewing angle. The camera is powered through the USB computer connection, is Interactive White Board (IWB) complaint for most recent boards, and includes Applied Vision 4 software for Windows (Windows XP SP2 or later, Vista, 7), Mac (OS 10.5 or later), and Linux.

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.
Ken-A-Vision Manufacturing, founded in 1957 and headquartered in Kansas City, MO, manufactures educational products such as microscopes, cameras, and software.
