Cadmiae Selenide (ZnSe)
Bi-Convex Lentes
Etsi lentium bi-convexum obscurant aberrationes in condicionibus ubi distantiae objecti et imaginis aequales vel subaequales sunt, cum inter lens bi-convexum vel DCX et lens plano-convexum statuendum est, ex quibus utraque causa incidentium lucis ad concursum collimatum est. soleat potior eligere bi-convexum lens ad aberrationes obscurandas, si ratio obiecti et distantiarum imaginum (ratio absoluta coniugata) est inter 5:1 et 1, 5. Extra hunc ambitum lentium plano-convexum praeferri solent.
ZnSe lentium aptissima sunt maxime ad usum lasers cum summus potentia CO2 . Optica paralight offert Zinc Selenide (ZnSe) Bi-Convex lentium promptum cum broadband AR efficiens optimized pro 8 ad 12 μm extensionis spectris in utraque superficie deposita. Haec efficiens multum remittit altam superficiem reflexionis subiecti, praebens mediocris transmissio in excessu 97% super totam range AR efficiens. Reprehendo Graphs sequentibus pro v.
