Zinc Selenide (ZnSe)
Lilense tsa Bi-Convex

Bi-Convex kapa Double-Convex (DCX) Lilense tsa Spherical (DCX) li chitja 'me li na le kobeho e ts'oanang ka mahlakoreng a mabeli a lense, kahoo lia lekana 'me li na le bolelele bo nepahetseng.Ha unit conjugation, koma le ho sotha lia tima ka lebaka la symmetry.Lilense tsena li ka sebelisoa ho shebana le leseli le kenang 'me li tumme bakeng sa lits'ebetso tse ngata tsa ho nka litšoantšo tse sa feleng.

Leha lilense tsa Bi-convex li fokotsa ho kheloha maemong ao sebaka le sebaka sa setšoantšo se lekanang kapa se batlang se lekana, ha u etsa qeto pakeng tsa lense ea bi-convex kapa DCX le lense ea plano-convex, tseo ka bobeli li bakang hore leseli la ketsahalo e kopaneng le kopane, hangata ho molemo ho khetha lense ea bi-convex bakeng sa ho fokotsa ho kheloha haeba karo-karolelano ea ntho le sebaka sa setšoantšo (karolelano e felletseng ea conjugate) e pakeng tsa 5:1 le 1:5.Ka ntle ho sebaka sena, hangata ho khethoa lilense tsa plano-convex.
