Achromatic lens: A lens which refracts light of most colours equally, i.e. corrected for blue and green light of the primaries.
消色差透镜:能够把大多数色光作等量折射的透镜。是消除三原色里的蓝光和绿光的色差。
Apochromatic lens: Compound lens corrected for chromatic aberration, i.e. the three primary colours, red, green and blue are corrected. Also called Apochromat.
复消色差透镜:矫正色差的复合式透镜：即是红、绿和蓝三原色的色差都已矫正。
symmetrical (achromat)lens
对称式(消色差)透镜
aplanat [aplanatic] lens

Anastigmatic lens: Photographic lens corrected for astigmatism as well as other distortions. Process camera lenses are anastigmats.
消像差透镜:消除纵横像差和其他畸变的摄影用透镜。制版照相机所用的镜头是消像差透镜。
Aperture:Compound lens corrected for spherical aberration and coma. Also called Aplanat.
消球差透镜:矫正球面销售量差和慧星差的复合式透镜。

Chromatic aberration: A lens fault in which different coloured lights do not converge on the same plane causing a blur image.
色差:透镜缺点之一。不同颜色的光线不能集中在同一平面上，造成模糊影像。
