IZinc Selenide (ZnSe)
IiLensi zePlano-Concave
Iilensi zePlano-concave zisebenza kakuhle xa into kunye nomfanekiso ukwi-absolute conjugate ratios, enkulu kuno-5:1 okanye ngaphantsi kwe-1:5. Kule meko, kunokwenzeka ukunciphisa i-spherical aberration, coma, kunye nokuphazamiseka. Ngokufanayo neelensi zeplano-convex, ukuphumeza ukusebenza kakuhle okuphezulu umphezulu ogobileyo kufuneka ujongane nomgama wento enkulu okanye i-conjugate engapheliyo ukunciphisa ukuphambuka okungqukuva (ngaphandle kwaxa isetyenziswa ngeelaser ezinamandla apho oku kufuneka kubuyiselwe umva ukuze kupheliswe ukubakho kwenyani. gxila).
Iilensi ze-ZnSe zifaneleke ngokukodwa ukusetyenziswa kunye ne-CO2 yamandla aphezulu okanye i-CO2 lasers. Ukongezelela, banokubonelela ngokusasazwa okwaneleyo kummandla obonakalayo ukuvumela ukusetyenziswa kwe-beam yokulungelelaniswa okubonakalayo, nangona ukubonakaliswa ngasemva kunokuvakaliswa ngakumbi. IParalight Optics ibonelela ngeZinc Selenide (ZnSe) iiLensi zePlano-Concave (PCV) ezifumaneka nge-broadband AR coating elungiselelwe i-2 µm - 13 μm okanye i-4.5 - 7.5 μm okanye i-8 - 12 μm uluhlu lwe-spectral olufakwe kuzo zombini iindawo. Olu gquba lunciphisa kakhulu ukubonakala okuphezulu komphezulu we-substrate, ivelisa umndilili wosasazo ongaphezulu kwama-92% okanye ama-97% kulo lonke uluhlu lokutyabeka lwe-AR.
