The Ken-A-Vision ESH101 Professor cordless, monocular compound microscope has upper and lower LED lighting, a 10x widefield eyepiece with 4x, 10x, and 40xS objective lenses, and is designed for biological use and educational applications. The monocular head has a fixed 45-degree incline and 360 degree rotation for comfortable viewing and a total magnification up to 400x. One knob for coarse and fine focus eases focusing for young users. The square stage has clips to hold the slide in place and rack-and-pinion movement. Built-in upper and lower, bright and cool white LED lighting with on/off switch provides a range of lighting options. The cordless microscope requires three AA batteries (included) and includes a cover, slides with a storage box, 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.
