lenses bi-convex (ma ọ bụ lenses abụọ convex) na-arụ ọrụ nke ọma mgbe ihe ahụ dị nso na oghere na ọnụ ọgụgụ conjugate dị ala. Mgbe ihe na anya ihe oyiyi hà nhata (1: 1 na-ebuwanye ibu), ọ bụghị nanị na a na-ebelata aberration spherical, kamakwa mgbagwoju anya, na aberration chromatic na-akagbu n'ihi ihe ngosi. Yabụ na ha bụ nhọrọ kacha mma mgbe ihe na onyonyo nọ na oke njikọ zuru oke dị nso na 1:1 yana mbanye ntinye na-agbanwe agbanwe. Dị ka usoro isi mkpịsị aka, lenses bi-convex na-arụ ọrụ nke ọma n'ime opekempe aberration na ọnụ ọgụgụ conjugate n'etiti 5:1 na 1:5, a na-eji ha eme ihe maka foto relay (Ezigbo Ihe na Oyiyi). Na mpụga oke a, lenses plano-convex na-adabarakarị.

N'ihi mgbasa ya dị elu site na 0.18 µm ruo 8.0 μm, CaF2 na-egosipụta index refractive dị ala dị iche iche site na 1.35 ruo 1.51 ma na-ejikarị eme ihe maka ngwa na-achọ nnukwu nnyefe na infrared na ultraviolet spectral ranges. Calcium fluoride dịkwa mma nke ukwuu ma na-enye ike dị elu ma e jiri ya tụnyere barium fluoride ya na ndị ikwu magnesium fluoride. Paralight Optics na-enye lenses nke Calcium Fluoride (CaF2) Bi-Convex dị na mkpuchi brọdband AR kachasị maka 2 µm ruo 5 μm spectral nso nke edobere n'elu abụọ ahụ.
