Izinzuzo zeCalcium Fluoride – CaF2 lens namawindi

I-Calcium Fluoride (CaF2) ingasetshenziselwa amafasitela abonakalayo, amalensi, amaprism kanye nezikhala endaweni ye-Ultraviolet ukuya endaweni ye-Infrared.Kuyinto eqinile uma kuqhathaniswa, iqine ngokuphindwe kabili kune-Barium Fluoride.I-Calcium Fluoride material yokusetshenziswa kwe-Infra-red ikhuliswa kusetshenziswa i-fluorite embiwa ngokwemvelo, ngamanani amakhulu ngezindleko eziphansi uma kuqhathaniswa.Izinto ezingavuthiwe ezilungiselelwe ngamakhemikhali ngokuvamile zisetshenziselwa izinhlelo ze-UV.

Inenkomba ye-refractive ephansi kakhulu evumela ukuthi isetshenziswe ngaphandle kwe-anti reflective coating.Amafasitela e-Calcium Fluoride anezindawo ezipholishiwe azinzile futhi azohlala iminyaka eminingana ngaphansi kwezimo ezijwayelekile kuze kube yilapho amazinga okushisa enyuka aze afike ku-600°C lapho eqala ukuthamba.Ezimweni ezomile inezinga lokushisa eliphakeme lokusebenza elingu-800°C.Amafasitela e-Calcium Fluoride angasetshenziswa njengekristalu ye-laser noma ikristalu ethola imisebe ngokuyifakela ngezinto ezifanele zomhlaba eziyivelakancane.Kuyikristalu ezinzile kumakhemikhali nangokomzimba enezici ezinhle kakhulu zokumelana namanzi, ukumelana namakhemikhali kanye nezici ezimelana nokushisa.Inikeza ukumuncwa okuphansi nokudluliswa okuphezulu okusuka kuVacuum Ultraviolet 125nm kuya ku-Infra-red 8 microns.I-optical dispersion yayo ehlukile isho ukuthi ingasetshenziswa njengelensi ye-achromatic ehlanganiswe nezinye izinto ezibonakalayo.

Zonke lezi zakhiwo zikhuthaza ukusetshenziswa okubanzi kwesayensi yezinkanyezi, ukuthwebula izithombe, i-micrscopy, i-HDTV optics namathuluzi e-laser yezokwelapha.Amafasitela e-Calcium Fluoride angenziwa nge-vacuum ultraviolet grade Calcium Fluoride evame ukutholakala ezinhlelweni zokucabanga ezishisayo ezipholile.Njengoba izinzile ngokomzimba futhi inezimboni zamakhemikhali ezinobunzima obuphakeme, iyinto ekhethwayo yezinhlelo zokusebenza ze-microlithography kanye ne-laser optics.Amalensi e-Achromatic Calcium Fluoride angasetshenziswa kuwo womabili amakhamera kanye nezibonakude ukuze kuncishiswe ukuhlakazeka kokukhanya kanye nasembonini kawoyela negesi njengengxenye kuma-detectors nama-spectrometer.
