N a defect of optical systems that arises when light striking a mirror or lens near its edge is focused at different points on the axis to the light striking near the centre. The effect occurs when the mirror or lens has spherical surfaces 球面像差 [physics]
Aspheric lenses are highest quality molded and fire polished lenses, designed to minimize spherical aberrations which are of major concern in condensing systems.
我们生产的非球面透镜质量最好，采用火焰抛光透镜，使球面相差最小化-对冷凝系统尤为重要。
Results: Total higher order aberrations, spherical aberration, horizontal primary coma, and vertical primary coma, were increased significantly with increasing pupil size.
结果：总高阶相差、水平彗差、垂直彗差和球差均随瞳孔直径的增大而增大；
The spherical equivalent refraction was significantly in positive correlation with the lower-order, total higher-order, 3rd and 5th order wavefront aberrations.
球镜度数与低阶像差、总体高阶像差、第3，5阶像差均存在明显的正相关。
