已经设计了一种具有径向梯度折射率函数分布的单片摄影透镜。一个相对孔径为f/6.3,半视场角为25度的单透镜校正了球差、彗差、予午与弧矢场曲。这些象差是指总的,而不是三级、五级等。该透镜的性能是与相对孔径为f/11、采用均匀介质的、具有最佳设计的同类型式的单透镜相当。 A monolithic photographic lens having a radial gradient index function distribution has been designed. A single lens with a relative aperture of f / 6.3 and a half angle of view of 25 degrees corrected for spherical aberration, coma, and afternoon and sagittal curvature. These aberrations refer to the total, not three, five and so on. The performance of this lens is equivalent to a single lens of the same type with the best design, using a uniform medium with a relative aperture of f / 11.
