# 光學透鏡的一些句子翻譯

Like plano-convex lenses, double convex lenses have positive focal lengths and form both real and virtual images. Symmetry is assured by finishing both surfaces with the same tool. Because of symmetry, aberrations including coma, distortion and lateral chromatic aberration almost exactly canceled at unit conjugate radio. Double-convex lenses have shorter focal lengths than plano-convex lenses of equal diameter and surface radius

Like plano-convex lenses, double convex lenses have positive focal lengths and form both real and virtual images. Symmetry is assured by finishing both surfaces with the same tool. Because of symmetry, aberrations including coma, distortion and lateral chromatic aberration almost exactly canceled at unit conjugate radio. Double-convex lenses have shorter focal lengths than plano-convex lenses of equal diameter and surface radius跟平凸的透鏡一樣, 雙凸透鏡有正的焦距和同時形成實像和虛像。使用相同的工具來加工兩個表面以確保對稱。因為對稱，像差, 包括彗形像差、畸變和橫向色差在共軛的無線電單元幾乎是完全抵消的。相等直徑和表面半徑的雙凸透鏡比平凸的透鏡有更短的焦距。
