The National Optical 188 cast aluminum, handheld, 60x stand microscope has both inch and metric scales (0.001"/0.02mm x 100), a 10x widefield eyepiece with 6x lens objective, a transparent base plate that holds specimens in place for viewing, and an adjustable penlight, and is used to measure the thickness, height, or depth of specimens. The microscope has a 3.0mm field diameter and a 23mm working distance. The penlight is attached to the body of the microscope on a swivel mount that can be adjusted to provide hands-free illumination. A rack-and-pinion system with coaxial focus knobs focuses specimens and a diopter-adjustable, soft rubber eyepiece focuses the built-in reticle. An adjustable penlight attached to base can be adjusted to provide hands-free illumination (requires two AA batteries, included). The cast aluminum base provides durability for field and classroom use. The microscope includes a carrying case.

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.
National Optical and Scientific Instruments manufactures microscopes and microscope cameras. The company, founded in 1991, is headquartered in Schertz, TX.
