the radius of curvature is ___a. inside the lensb. the focal lengthc. twice the focal lengthd. half the focal length 相关知识点: 试题来源: 解析 答案C设抛物线方程为x^2=2py 符合该方程的平抛运动的参数方程为:y=1/2gt^2,x=vt 改写参数方程得:y=2gx^2/v^2 于是2p=v^2/2g 在最高点...
Aspheric lens, the radius of curvature varies with the center axis, to improve optical quality, reduce optical elements, reduce the design cost. Aspherical lens has unique advantages over spherical lens, so it has been widely used in optical instrument, image and optoelectronic industry, such as ...
PURPOSE:To judge the refractivity and the radius of curvature by arranging a processing part by which a signal from a detecting part which discriminates a dot printing part for applying dots on the lens and the radius of curvature is converted to a radius of curvature value and a display ...

A lens is a piece of transparent material, usually circular in shape, with two polished surfaces, either or both of which is curved and may be either convex (bulging) or concave (depressed). The curves are almost always spherical; i.e., the radius of curvature is constant. A lens has ...

radius of curvature of the second surface of the lens = -r2 Considering refraction at the first surface AOB of the lens we have, μ2v′−μ1u=μ2−μ1r1…. (1) [both object and image are real] Considering refraction at the second surface AO’B of the lens we have, ...
radius ofcurvatureis constant. A lens has the valuable property of forming images of objects situated in front of it. Single lenses are used ineyeglasses, contact lenses, pocket magnifiers, projection condensers, signal lights, viewfinders, and on simple box cameras. More often a number of ...
