Muraayadaha laba-convex (ama laba-convex lenses) ayaa si fiican u shaqeeya marka shaygu u dhow yahay muraayadda oo saamiga isku-xidhku uu hooseeyo. Marka shayga iyo masaafada sawirku siman yihiin (1:1 waynaynta), ma aha oo kaliya in la yareeyo aberration spherical, laakiin sidoo kale qallooca, iyo aberration chromatic waa la tirtiray summaynta awgeed. Markaa waxay yihiin xulashooyinka ugu fiican marka shayga iyo sawirku ay ku jiraan saamiyo isku dhafan oo dhammaystiran oo ku dhow 1: 1 oo leh alwaaxyo wax gelin ah oo kala duwan. Sida qaanuunka suulka ah, muraayadaha bi-convex waxay si fiican u fulaan inta ugu yar ee nusqaanka ah ee saamiga isku dhafka ah ee u dhexeeya 5: 1 iyo 1: 5, waxaa loo isticmaalaa codsiyada gudbinta (Waxyaabaha Dhabta ah iyo Sawirka). Kala duwanaanshahan ka baxsan, muraayadaha plano-convex ayaa inta badan ku habboon.
Sababo la xiriira gudbintiisa sare ee 0.18 µm ilaa 8.0 μm, CaF2 waxay soo bandhigaysaa index refractive hooseeya oo ka duwan 1.35 ilaa 1.51 waxaana caadi ahaan loo isticmaalaa codsiyada u baahan gudbin sare ee infrared iyo ultraviolet spectral spectral. Calcium fluoride sidoo kale waa si cadaalad ah kiimiko ahaan aan firfircoonayn wuxuuna bixiyaa adayg ka sarreeya marka loo eego barium fluoride, iyo ina-adeerayaasha magnesium fluoride. Paralight Optics waxay bixisaa Lenses-ka Calcium Fluoride (CaF2) Bi-Convex Lenses oo la heli karo daahan ballaaran oo AR ah oo loo habeeyay 2 µm ilaa 5 μm kala duwanaansho muuqaal ah oo lagu kaydiyay labada dusha. Dahaarkani wuxuu si weyn u yareynayaa celceliska milicsiga substrate-ka in ka yar 1.25%, taasoo keenaysa gudbin celcelis ka badan 95% dhammaan noocyada daahan AR.
