The Ken-A-Vision trinocular research microscope with double-layer mechanical stage has LED lighting with dimmer control and on/off switch, a 10x widefield eyepiece with reverse-mounted 4x, 10x, 40x, and 100x lens objectives with humidity and climate control protection, and is designed for biological use and educational applications. The Seidentopf binocular head has a 30-degree inclination, variable-width eye pieces, and 360-degree rotation for comfortable viewing. The monocular objective has individual focus + or - 0.20x for varied eye strength between viewers, or can accept a camera connection (not included). A choice of DIN achromatic, semi-plan achromatic, plan achromatic, infinity achromatic, infinity semi-plan, and infinity plan objectives are spring-loaded to prevent slide damage and provide a range of focus options. Separate coaxial knobs for coarse and fine focus provide sharp focus. The double-layer mechanical stage has clips to hold the slide in place, and separate control for X- and Y-axis adjustment. Built-in 20W (12V) halogen Kohler illumination provides uniformity of light when taking photomicrographs. The single-cast aluminum body is strong and durable. The microscope is powered by external 110V power supply, and includes a cover and instructions.

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.
