The AmScope PS50A microscope slide set includes 50 prepared slides of a variety of biology and pathology slides used in basic biology education. The samples are preserved in cedar wood oil and sealed with a coverslip to preserve specimens and prevent contamination. Labeling on each slide identifies specimens. Slides are composed of optical glass for clear viewing and are 3 x 1 x 0.4 inches/75 x 25 x 1mm (H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) The set comes in a fitted wooden case to prevent breakage and ease handling.

Set A slide specimens include ascarid egg (whole mount), Aspergillus (whole mount), cabbage (Hydrilla verticillata, longitudinal section), coprinus mushroom set (cross section), cotton stem (cross section), Cucurbita stem (longitudinal section), dandelion fuzz (whole mount), dense connective tissue (section), dog cardiac muscle (longitudinal section), dog esophagus (cross section), dog skeletal muscle (longitudinal and cross section), dog small intestine (section), dog smooth muscle (longitudinal and cross section), dog squamous epithelium (whole mount), dog stomach (section), earthworm (cross section), honeybee leg (whole mount), honeybee mouth parts (whole mount), honeybee wings (whole mount), housefly mouth parts (whole mount), human blood (smear), hydra (longitudinal section), Hydrilla verticillata leaf (whole mount), leaf of winter jasmine (cross section), Lilium anther (cross section), Lilium ovary (cross section), locust wing (whole mount), loose connective tissue (whole mount), mantis wing (whole mount), nymphasa (spongy tissue) (cross section), nymphasa aqustio stem (cross section), onion epidermis (whole mount), penicillium (whole mount), pig motor nerve (whole mount), pine leaf (cross section), pine pollen (whole mount), pine stem (cross section), pumpkin stem (cross section), rabbit artery and vein (cross section), rabbit hyaline cartilage (section), rabbit lymph node (section), rabbit spinal cord (cross section), rabbit testis (section), stomata-vicia faba leaf (whole mount), sunflower stem (cross section), Tilia stem (cross section), wool sheep (whole mount), young root of broad bean (cross section), Zea stem (cross section), Zea stem (longitudinal section),

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.

United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The company, founded in 1996, is headquartered in Irvine, CA.
