The Ken-A-Vision T-19241C Comparison Scope 2 has two side-by-side compound microscopes, each with a reverse four-hole nosepiece with 2x, 4x, 10x, and 40xS DIN achromatic lens objectives that are connected by a bridge with a Seidentopf binocular head with a 30-degree incline and variable-width eyepieces, for side-by-side comparison of forensic samples, including shell casings, and hair and tissue samples. Samples can be viewed full field (individually) or side-by-side on a split screen at up to 400x magnification. Each microscope has separate upper and lower cool LED lighting that provide both incidental (upper) and transmitted (lower) light and separate on/off switches. Lower-level lighting has a dimmer control. Independent coaxial coarse and fine focus knobs provide sharp focus for viewing specimens. The DIN achromatic lens objectives have a humidity and climate control coating to protect lenses in harsh environments. The floating stage is mounted on a rack-and-pinion gearing system and has two spring-loaded clips to hold samples in place. The microscope bases have built-in, retractable handles for safe transport, NiMH rechargeable batteries for use away from power sources, and a single-cast aluminum body with a polymer coated base for strength and durability during daily use. The microscope includes two power supplies, 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.
