折光度

Dioptre

屈光度或屈光度是透镜或曲面镜的光焦度的测量单位,其等于以米计的焦距的倒数。 因此它是相互长度的单位。 例如,3屈光度透镜将平行光线聚焦在1/3米处。 有时候,相同的单元有时也用于距离的其他倒数,特别是曲率半径和光束的聚光。 法国眼科医生费迪南德·蒙约(Ferdinand Monoyer)在1872年提出了这一用途,这是基于早期使用约翰尼斯·开普勒术语“狄更斯”一词。 使用光学功率而不是焦距的主要优点是透镜制造商的方程具有物体距离,图像距离和焦距全部为倒数。 另一个好处是,当相对薄的透镜靠近放置在一起时,它们的功率大约增加。 因此,靠近薄的0.5屈光度透镜放置的薄的二屈光镜透镜产生与2.5屈光度镜片几乎相同的焦距。 A dioptre, or diopter, is a unit of measurement of the optical power of a lens or curved mirror, which is equal to the reciprocal of the focal length measured in metres. It is thus a unit of reciprocal length. For example, a 3-dioptre lens brings parallel rays of light to focus at 1⁄3 metre. The same unit is also sometimes used for other reciprocals of distance, particularly radii of curvature and the vergence of optical beams. The usage was proposed by French ophthalmologist Ferdinand Monoyer in 1872, based on earlier use of the term dioptrice by Johannes Kepler. The main benefit of using optical power rather than focal length is that the lensmaker's equation has the object distance, image distance, and focal length all as reciprocals. A further benefit is that when relatively thin lenses are placed close together their powers approximately add. Thus, a thin 2-dioptre lens placed close to a thin 0.5-dioptre lens yields almost the same focal length as a 2.5-dioptre lens would have.

在英语 词典里dioptre的定义

字典中的屈光度的定义是用于测量镜片的屈光力的单位:以米表示的镜片的焦距的倒数。

The definition of dioptre in the dictionary is a unit for measuring the refractive power of a lens: the reciprocal of the focal length of the lens expressed in metres.
