The Ken-A-Vision TU-19031C Basic Siedentopf Binocular Compound Microscope has a pair of 10x widefield (one with pointer), a reverse-mounted nosepiece with four DIN achromatic objectives, LED illumination, coaxial nested coarse and fine focus, a 1.25 NA Abbe condenser with iris diaphragm, and a mechanical stage. The Siedentopf binocular head has a pair of eyepieces with interpupillary adjustment, a fixed inclination to reduce eye and neck strain, and rotation capability to provide a more comprehensive view and enable sharing. A Siedentopf binocular head enables the viewer to change the interpupillary distance without changing the tube length, eliminating the need to refocus the image. Dioptric adjustment in one eyepiece accommodates individual eye-strength differences. An eyepiece pointer is used to identify features for students. A reverse-mounted nosepiece keeps objectives out of the way to prevent damage and contamination, and to enable more secure slide handling. Rotation positions with secure, positive stops ensure accurate positioning and support a range of magnification options. Achromatic objectives that provide color correction of magnified images. The 40xS and 100xS objectives are spring-loaded objectives that retract when they come into contact with the stage or slide, preventing slide damage when focusing. The 100xS objective is also an oil objective that provides increased resolution over a standard objective. A basic compound microscope is used in classroom, home school, and hobbyist settings for inspection and dissection of specimens when two-dimensional images are desired.
The microscope has lower (diascopic) brightfield illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background. The LED light source provides bright, cool light for working with temperature-sensitive or live specimens, and operates on AC power or on rechargeable batteries for cordless operation. The USB charging system charges via AC power or USB port. A rheostat controls the amount of light emanating from the lamp. The Abbe condenser can be adjusted to control the distance of the light from the stage, and has an iris diaphragm to optimize the amount of light illuminating the specimen. The condenser is controlled using a rack-and-pinion mechanism. The mechanical stage locks the slide into place and provides precise slide manipulation along the X- and Y-axes. Coaxial coarse and fine focus knobs are nested to speed focusing for left-and right-handed viewers. The cast aluminum frame provides durability. The built-in handle allows the microscope to be safely transported.

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.
