摘　　要：当今光学仪器中,大都使用球面透镜,而这种透镜易形成较大像差,非球面透镜能够克服球面透镜的缺点,具有很高的实用价值.本文给出几种无球差光学曲面和无球差透镜,利用这种透镜能提高光学仪器的成像质量、简化内部结构.Among the optical equipments spherical surface lens has been used widely today. But this kind of lens forms big aberration easily. Non-spherical surface lens can get rid of the spherical surface lens' shortcoming and will be highly valuable. This article gives some optical surfaces and lens that have no spherical aberration, with this type of lens can raise the quality of formation that images by optical equipments and simplify their structure inside.
