Icalcium Fluoride (CaF2)
IiLensi zeBi-Concave

I-Bi-concave okanye i-Double-concave (i-DCV) iilensi ziilensi ezingezizo ezityebileyo emphethweni kunasembindini, xa ukukhanya kudlula kuzo, kuyahlukana kwaye indawo ekugxilwe kuyo yinyani. Iilensi ze-Bi-Concave zinerediyasi elinganayo yokugoba kumacala omabini enkqubo yokukhanya, ubude bazo obugxininiswe bunegetive, kunye neradiya yokugoba kwemiphezulu egobileyo. Ubude bojoliso obungalunganga bubangela ukuba ukukhanya kwesiganeko esidityanisiweyo kuhlukane, zihlala zisetyenziselwa ukuphambukisa umqadi oguqukayo. Ngenxa yeempawu zazo, iilensi ze-bi-concave ziqhele ukusetyenziswa ekwandiseni ukukhanya kwizandisi zodidi lwaseGalili okanye ukonyusa ubude obusebenzayo belensi eguqukayo ngokusebenzisa izibini kwiinkqubo ezikhoyo ezifana neenkqubo zokubonisa ukukhanya. Zikwaluncedo xa kufikwa ekunciphiseni umfanekiso. Kwiinkqubo zamehlo, kuqhelekile ukukhetha i-optics yazo ngononophelo ukwenzela ukuba ii-aberrations eziziswe yi-positive- kunye nenegative-focal-length lens malunga nokurhoxisa. Ezi lensi zingalunganga ziqhele ukusetyenziswa kwiiteleskopu, iikhamera, iilaser okanye iiglasi ukunceda iinkqubo zokukhulisa ukuba zihlangane ngakumbi.

Iilensi ze-Bi-concave (okanye iilensi eziphindwe kabini) lolona khetho lungcono xa into kunye nomfanekiso zikumlinganiselo opheleleyo weconjugate (umgama wento owahlulwe ngokuhlukana komfanekiso) kufutshane no-1:1 kunye nemiqadi yokufaka yokuguqula, njengoko kunjalo nge-bi-convex. iilensi. Zisetyenziselwa ukwenza umboniso womdlalo kwakhona (izinto ezibonakalayo kunye nomfanekiso) izicelo. Xa ukwandiswa okupheleleyo okufunekayo kungaphantsi kwe-0.2 okanye ngaphezulu kwe-5, iilensi zeplano-concave zihlala zifanelekile.

Ngenxa yokuhanjiswa kwayo okuphezulu ukusuka kwi-0.18 µm ukuya kwi-8.0 μm, i-calcium fluoride ibonisa isalathisi esisezantsi se-refractive ukusuka kwi-1.35 ukuya kwi-1.51 kwaye isetyenziswa ngokuqhelekileyo kwizicelo ezifuna ukuhanjiswa okuphezulu kwi-infrared kunye ne-ultraviolet spectral ranges, ine-infrared index ye-1.428 kwi-1.428 µm. I-CaF2 ikwanekhemikhali inert kwaye inika ubunzima obuphezulu xa kuthelekiswa ne-barium fluoride, kunye nabazala be-magnesium fluoride. Umda wayo womonakalo welaser uphezulu kakhulu uyenza ukuba luncedo ekusebenziseni iilaser zeexcimer. I-Paralight Optics ibonelela ngeCalcium Fluoride (CaF2) iilensi zeBi-concave ezineeconsi ezithintela ukukhanya nokuba kuluhlu lwe-3 ukuya kwi-5 µm ubude bobude bamaza. Olu gquba luwunciphisa kakhulu umndilili wokubonakaliswa kwesubstrate engaphantsi kwe-2.0%, ivelisa umndilili ophezulu wosulelo olungaphezulu kwama-96% kulo lonke uluhlu lokutyabeka lwe-AR.
