Unit Information

Diopter (D)

Definition: A unit of optical power equal to the reciprocal of focal length in meters.

History: From Greek "dioptra" meaning optical instrument.

Current Use: Used in optometry for lens prescriptions.

Magnifying Power (MP)

Definition: A dimensionless unit representing the ratio of the apparent size of an object seen through an optical instrument to its actual size.

History: Used historically and presently in optics and microscopy to describe image enlargement.

Current Use: Describes the magnification of lenses, microscopes, and telescopes.

Pixel per Centimeter (px/cm)

Definition: A unit of pixel density, measuring pixels per centimeter.

History: Metric equivalent of pixels per inch.

Current Use: Used in metric countries for resolution measurements.

Pixel per Inch (ppi)

Definition: A unit of pixel density, measuring pixels per inch of display.

History: Developed with digital displays.

Current Use: Standard unit for display and print resolution.

Prism Dioptre (Δ)

Definition: A unit of prism power where 1Δ displaces an image by 1 cm at a distance of 1 m.

History: Used in ophthalmology and orthoptics to quantify prismatic deviation.

Current Use: Describes the strength of prisms in glasses and vision therapy.
