Ubungakanani obukhulu bokuSebenza bokuSebenza

Iilensi zamehlo ezinobungakanani obukhulu (ngokuqhelekileyo zibhekisa kumalungu abonayo anobubanzi obusuka kumashumi eesentimitha ukuya kwiimitha ezininzi) zidlala indima ebalulekileyo kubuchwephesha banamhlanje bokubona, kunye nosetyenziso oluthatha imimandla emininzi efana nokuphononongwa kweenkwenkwezi, ifiziksi yelaser, ukwenziwa kwamashishini, kunye nezixhobo zonyango. Oku kulandelayo kucacisa iimeko zesicelo, umsebenzi, kunye neemeko eziqhelekileyo:

1,UkwaPhumelela kokuQokelelwa kokuKhanya

Umgaqo: Ubungakanani obukhulu be-lens buhambelana ne-light-aperture enkulu (indawo esebenzayo), eyenza ukuqokelela amandla okukhanya amaninzi.

Iimeko zesicelo:

Uphononongo Lweenkwenkwezi: Umzekelo, iilensi zeberyllium ezili-18 ezinkulu zeJames Webb Telescope zibamba ukukhanya kwenkwenkwezi okuncinci ukusuka kwi-13 billion light-year kude ngokwandisa indawo yokuqokelela ukukhanya.

2, ukuPhuculwa kweSisombululo se-Optical kunye nokuchaneka komfanekiso

Umgaqo: Ngokwekhrayitheriya yeRayleigh, ubukhulu be-lens aperture, iphezulu i-diffraction-limited resolution (ifomula: θ≈1.22λ/D, apho u-D iyidayamitha yelensi).

Iimeko zesicelo:

IiSathelayithi zoVavanyo olukude: Iilensi zenjongo ezinkulu (umzekelo, iilensi eziziimitha ezi-2.4 zesathelayithi ye-Keyhole yase-US) zinokucombulula iithagethi zomhlaba kwisikali se-0.1 yeemitha.

3, Ukumodareyithwa kweSigaba sokuKhanya, iAmplitude, kunye nePolarization

Ukuqonda koBuchule: Iimpawu zokukhanya ezingaphambili zitshintshwa ngoyilo lwemilo yomphezulu (umzekelo, iparabolic, iaspheric surfaces) okanye iinkqubo zokugquma kwilensi.

Usetyenziso oluqhelekileyo:

I-Gravitational Wave Detectors (LIGO): Iilensi ze-silica ezidibeneyo ezinobungakanani obukhulu zigcina ukuzinza kwesigaba sokuphazamiseka kwe-laser ngokusebenzisa iimilo ezichanekileyo eziphezulu (iimpazamo <1 nanometer).

Iinkqubo ze-Polarization Optical: I-polarizers enkulu okanye iipleyiti zamaza zisetyenziselwa izixhobo zokucwangcisa i-laser ukulawula imeko ye-polarization ye-laser kunye nokwandisa iziphumo zokulungiswa kwezinto.
