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.
