I-Thorlabs reflective fiber collimator isekelwe esibukweni esingu-90° off-axis paraboloid (OAP) esinobude obugxilile obungaguquki phezu kwebanga elibanzi lamaza futhi ilungele ukusetshenziswa ezinhlelweni ezidinga ukungqubuzana kwamaza amaza amaningi.
I-collimator ekhanyayo iyatholakala ngemiklamo emithathu yezindlu, ngayinye ihambisana nama-fiber jumpers ane-FC/PC, FC/APC, noma izixhumi ze-SMA.
Izisekelo ze-OAP Reflector
I-OAP(Off-Axis Parabolic) Reflector iyingxenye ye-parabolic yomzali wayo.
I-off-eksisi isho ukuthi ama-eksisi okubona kokubili ayahambisana kodwa awaqondani.
I-focus axis idlula phakathi nendawo yokugxila kanye ne-OAP Reflector,futhi ibanga eliphakathi kwalawa maphuzu amabili libizwa ngokuthi ubude bendawo obubonisiwe(I-RFL).
I-engeli ephakathi kwe-axis yokugxila kanye ne-optical axis i-off-axis Engela,okungama-degree angama-90 lapha.
I-Collimator Elungisiwe
Ama-fiber collimator angaguquki ahlinzeka ngamafilimu amabili ensimbi abonisa phezulu: -F01 UV-ifilimu ye-aluminium ethuthukisiwe kanye nefilimu yesiliva -P01 enesendlalelo sokuzivikela, okuyikunconyelwe ukuhlangana kwe-fiber yemodi eyodwa kanye ne-multimode futhiizinhlelo zokusebenza zokuhlanganisa i-multimode fiber.
Ngokusho kobubanzi be-collimated beam (ye-fiber engu-0.13 NA), ingabaihlukaniswe ngochungechunge olune olulandelayo:
Izithombe ezine ngenhla yi-RC02FC-P01, RC04FC-P01, RC08APC-P01 kanyeI-RC12SMA-P01 ngokulandelana.
Ngakho-ke, ngokusho kwemodeli yomkhiqizo, singakwazi ukwazi imingcele eyinhlokoye-collimator ngayinye ekhanyayo, okuhlanganisa ububanzi be-collimated beam, i-fiberisixhumi kanye enamathela.
Ama-collimator e-RC02, RC04, kanye ne-RC08 ahambisana ne-SM05- yangaphakathi.ama-mounted mounted, kuyilapho i-RC12 collimator ihambisana ne-SM1- yangaphakathiama-mounted mounts.
Ngaphezu kwalokho, i-RC02 collimator ingafakwa ekugcineni ngqo ku-Ø1/2"i-kinematic mount, kuyilapho i-RC02, RC04, ne-RC08 ingafakwa ekugcineni ngqoungene ku-Ø1" kinematic mount (ngemuva kokukhulula okokuqala iringi eguquliwe mahhalaimbobo yesikhala);
Ukukhweza nge-kinematic mount kusiza ukuqondanisa kwe-beam lapho i-fiber ihlanganaiyadingeka.
I-Collimator encane
I-collimator encane ifinyelela umklamo omncane ngokuba nesibonisi ku-indlela ephambene ukuya phambili. Ingahlukaniswa ngochungechunge olubili ngokushoubude bokugxila: i-RCR25x-P01 kanye ne-RCR50x-P01, enobude bokugxilisa okuboniswayoka-25.4 kanye no-50.8 mm ngokulandelana; u-x enombolweni yemodeli iyifayibhauhlobo lwesixhumi, olungashintshwa ngo-P, A no-S ukumela i-FC/PC,I-FC/APC nezixhumi ze-SMA ngokulandelana kwazo.
Ama-collimator amancane angafakwa ngqo ku-Ø1/2" yama-lens tube mounts, anjalonjengendandatho yokushelela ye-SM05RC(/M) kanye ne-SM05TC clamp.
Uma kudingeka ukulungiswa kwe-pitch/yaw, kungakhwezwa ku-Ø1" kinematickhweza usebenzisa i-adaptha ye-SM1A60.
I-collimator encane ingabuye ihlanganiswe ngqo ekhejini elingu-16 mmUhlelo olusebenzisa ipuleti lekheji le-SP3 noma ikhyubhu yekheji ye-SC6W, noma ibe ngu-30 mmuhlelo lwekheji lisebenzisa i-adaptha ye-SM1A60 kanye nekhiyubhu yekheji ye-C4W.
I-Collimator Eguquguqukayo
Ama-collimator alungisekayo angalungisa ibanga ukusuka ku-fiber ukuya esibukweni se-OAP ukuze kuthuthukiswe ukungqubuzana kwefayibha ngayinye noma ukubhangqa ukukhanya ku-singlemode noma imicu ye-multimode.
Uma umugqa obhaliwe uqondaniswe nophawu ∞, ibanga ukusuka ku-fiberku-reflector ye-OAP ilingana ne-RFL, futhi imiphumela ye-collimator augongolo oluhlanganisiwe (ngenhla).
Lapho umugqa obhaliwe uchezuka kuphawu ∞, i-collimator ikhipha augongolo oluhlukene noma oluguquguqukayo, kanye nebanga eliphezulu ukusuka ekugxilweni kwalo ukuyaisikhungo se-reflector singu -2.2 m kanye no-0.15 m, ngokulandelana, njengoba kuboniswe ku-kulandela izibalo ezimbili.
Uma isilinganiso se-conjugate silingana nokungapheli, izibuko ze-OAP zingafinyelelaizithombe ze-diffraction-limited.
Njengoba kukhonjisiwe esithombeni esingezansi, ama-collimator amabili aguquguqukayo nawo akhonaifaneleka kakhulu ukuhlangana okude, ukuze indawo emaphakathi yamahhalaugongolo lungaqondiswa nezinye izakhi ze-optical, eziwusizo kakhulu kuizicelo zokuxhumana amabanga amade.
I-RCF15x-P01 i-collimator elungisekayo ingafakwa kusiliphu se-SM1RC(/M)indandatho noma i-SM1TC sleeve clamp kusetshenziswa ingxenye emnyama.
Ukulungiswa kwe-pitch/yaw, kunconywa ukusebenzisa i-Polaris mount, njengei-POLARIS-K2 noma i-POLARIS-K2VS2L Ø2" ukukhweza kinematic usebenzisa i-AD2Ti-adaptha; intaba yekinematic enemicu ye-POLARIS-K2T SM2 isebenzisa i-SM2A21i-adaptha; noma i-POLARIS-K15XY 5-axis kinematic mount isebenzisa i-SM1L03I-lens tube kanye ne-adaptha ye-SM1A68.
Isiphetho sendawo yamahhala sezindlu ze-collimator ezilungisekayo sixhunywe ngasoi-SM05 yangaphakathi nemicu yangaphandle ye-SM1.
Izibonelo zokukhweza i-collimatorkuboniswa emifanekisweni emibili elandelayo.
I-Single Mode Fiber Collimation
Lapho kungqubuzana imicu yemodi eyodwa, lawa ma-collimator akhombisayo akhiqiza ububanzi- okhalweni, imishayo ehlukene kancane.
Ukuhlukana okuphelele kwe-beam ehlanganisiwe (ngamadigri) kungalinganiselwangobubanzi benkambu yemodi yefayibha (MFD) kanye nobude bokugxila kwesibonisi (RFL):
Ububanzi obungu-1/e² bomugqa ohlanganisiwe bucishe bube:
Isibonelo, ukusebenzisa i-RCR25A-P01 i-collimator encane ukuhlanganisa i-P3-I-630A-FC-1 i-fiber yemodi eyodwa, kubude begagasi buka-λ = 633 nm, i-MFD ingu-4.3µm.
Izibalo ezimbili ezingenhla zibonisa ukuthi i-engeli yokuhluka ingamadigri angu-0.01, futhi ububanzi be-beam buyi-4.8 mm.
I-Multimode Fiber Collimation
Isamba se-engeli yokuhluka kwe-engeli ehlanganisiwe cishe:
Ububanzi be-collimated beam bucishe bube:
Ukukhishwa kwefayibha ye-multimode kuvame ukungahambisani kahle.
Ngokusho kwefomula engenhla, ububanzi be-beam buthinteka kakhulu yi-NAendaweni eseduze nesibonisi se-OAP, kodwa njengoba ugongolo lusakazeka, iithonya ububanzi core liba sobala ngokwengeziwe.
Ku-collimator engaguquki okukhulunywe ngenhla, ububanzi be-collimated beam buibalwa nge-2NA*RFL, enkulu kunobubanzi be-beam obungu-1/e².
Uma ukhetha i-collimator engaguquki, ubude be-focal bungathathwa busuka ku-i-diameter ye-beam edingekayo ukuze kunqunywe imodeli efanelekile.
Kunemikhawulo emibili ebalulekile yokuhlanganisa imicu ye-multimode.
Okokuqala, izintambo eziningi ze-multimode zine-beam ehlukanisiwe kakhulu engabaivinjwe izindlu ngaphambi kokufinyelela isibonisi se-OAP, ngakho-ke i-fiber NAayikwazi ukweqa inani elithile; bheka ithebula eledlule ukuze uthole imininingwane.
Okwesibili, ukuhlukana kwe-beam ehlanganisiwe kuhlobene nomnyomboububanzi; njengoba ububanzi bomnyombo bukhula, i-NA ephezulu isekelwai-collimator iyancipha.
Uma i-diameter ye-collimated beam idlula indawo ecacile, okukhiphayougongolo luzovinjwa yizindlu.
Zombili lezi zimo zingaholela ekwehleni kwekhwalithi ye-beam.
Ngaphezu kwalokho, izibonisi ze-OAP zingangqubuzana ngokuphelele nemithombo yamaphuzu ku-indawo okugxilwe kuyo.
Okukhulu ukuchezuka komthombo wephoyinti ku-eksisi yokubona, noma i-mkhulu ububanzi be-multimode core, kukhulu ukuhlanekezela kwe-collimatedugongolo; ukwandisa ubude be-focal focal noma ubude be-waveleng kunganciphisaukuhlanekezela.
