I-Thorlabs reflective fiber collimator isekelwe esibukweni se-paraboloid (OAP) esingu-90°off-axis esinobude obuqondile obuhlala njalo phezu kobubanzi be-wavelength futhi ilungele ukusetshenziswa ezinhlelweni ezidinga i-collimation yama-wavelength amaningi.
I-collimator ekhanyayo itholakala ngemiklamo emithathu yezindlu, ngayinye ihambisana nama-fiber jumpers anezixhumi ze-FC/PC, i-FC/APC, noma i-SMA.
Izisekelo Zokugqamisa i-OAP
I-OAP (Off-Axis Parabolic) Reflector iyingxenye ye-parabolic yayo engumzali.
I-Off-axis isho ukuthi ama-optical alezi zi-axes ezimbili ahambisana kodwa awahambisani.
I-focus axis idlula phakathi nendawo yokugxila kanye ne-OAP Reflector,futhi ibanga eliphakathi kwala maphuzu amabili libizwa ngokuthi ubude obugqamile obubonakalayo(RFL).
I-engela ephakathi kwe-focus axis kanye ne-optical axis yi-engela ye-off-axis,okuyi-degrees ezingama-90 lapha.
I-Fixed Collimator
Ama-collimator e-fiber aqinile ahlinzeka ngamafilimu amabili ensimbi abonisa ukukhanya okuphezulu: -F01 UV-ifilimu ye-aluminium ethuthukisiwe kanye nefilimu yesiliva ye-P01 enesendlalelo esivikelayo, okuyiKunconywa i-single-mode kanye ne-multimode fiber collimation kanyeizinhlelo zokusebenza zokuhlanganisa i-fiber yemodi eminingi.
Ngokusho kobubanzi be-collimated beam (ye-fiber engu-0.13 NA), zingabaihlukaniswe ngochungechunge olune olulandelayo:
Izithombe ezine ezingenhla yi-RC02FC-P01, RC04FC-P01, RC08APC-P01 kanyeI-RC12SMA-P01 ngokulandelana.
Ngakho-ke, ngokwemodeli yomkhiqizo, singazazi izinhlaka eziyinhlokowe-collimator ngayinye ebonakalisayo, kufaka phakathi ububanzi be-collimated beam, i-fiberisixhumi kanye nesembozo.
Ama-collimator e-RC02, RC04, kanye ne-RC08 ayahambisana ne-SM05- yangaphakathiizikhonkwane ezinezintambo, kuyilapho i-RC12 collimator ihambisana ne-SM1- yangaphakathiizikhonkwane ezinentambo.
Ngaphezu kwalokho, i-RC02 collimator ingafakwa ngqo ku-Ø1/2"ukukhweza kwe-kinematic, kuyilapho i-RC02, i-RC04, kanye ne-RC08 zingafakwa ngqo ekugcineniku-Ø1" kinematic mount (ngemuva kokuvula indandatho egoqekile ku-freeichweba lasemkhathini);
Ukufaka nge-kinematic mount kwenza kube lula ukuvumelanisa imisebe lapho kuhlanganiswa i-fiberiyadingeka.
I-Collimator Encane
I-collimator encane ifinyelela umklamo omncane ngokuba ne-reflector kuisiqondiso esiphambene nengaphambili. Ingahlukaniswa ibe uchungechunge olubili ngokushoubude obugxile: RCR25x-P01 kanye ne-RCR50x-P01, obunobude obugxile bokubonisaka-25.4 no-50.8 mm ngokulandelana; u-x enombolweni yemodeli yi-fiberuhlobo lwesixhumi, olungashintshwa ngo-P, A kanye no-S ukuze lumele i-FC/PC,Izixhumi ze-FC/APC kanye ne-SMA ngokulandelana.
Ama-collimator amancane angafakwa ngqo kuma-lens tube mounts e-Ø1/2", njengokuthinjengendandatho yokushelela ye-SM05RC(/M) kanye ne-SM05TC clamp.
Uma kudingeka ukulungiswa kwephimbo/ukugoba, zingafakwa ku-kinematic ye-Ø1"faka usebenzisa i-adaptha ye-SM1A60.
I-collimator encane ingafakwa ngqo ekhejini elingu-16 mmuhlelo olusebenzisa ipuleti lekheji le-SP3 noma ikhiyubhu yekheji le-SC6W, noma lube yi-30 mmuhlelo lwekheji olusebenzisa i-adaptha ye-SM1A60 kanye ne-cube yekheji ye-C4W.
I-Collimator Elungisekayo
Ama-collimator alungisekayo angalungisa ibanga ukusuka ku-fiber kuya esibukweni se-OAP ukuze athuthukise i-collimation ye-fiber ngayinye noma ukuhlanganisa ukukhanya kube yi-singlemode noma i-multimode fibers.
Uma umugqa obhaliwe uhambisana nophawu lwe-∞, ibanga elivela ku-fiberku-reflector ye-OAP ilingana ne-RFL, kanti i-collimator ikhipha i-umsebe ohlanganisiwe (ngenhla).
Uma umugqa obhaliwe uphambuka kuphawu lwe-∞, i-collimator ikhipha u-umsebe ohlukanisiwe noma ohlangene, kanye nebanga eliphakeme kakhulu ukusuka ekugxilweni kwawo kuyaisikhungo sesibukisi singamamitha angu-2.2 kanye no-0.15, ngokulandelana, njengoba kuboniswe ku-kulandela izibalo ezimbili.
Uma isilinganiso se-conjugate silingana nokungapheli, izibuko ze-OAP zingafinyelelaizithombe ezilinganiselwe zokuphambuka.
Njengoba kuboniswe esithombeni esingezansi, ama-collimator amabili abonakalisayo alungisekayo nawo akhonaifaneleka kakhulu ekuhlanganiseni ibanga elide, ukuze isikhala samahhala esiphakathii-beam ingaqondiswa nezinye izinto ezibonakalayo, okuwusizo kakhuluizinhlelo zokusebenza zokuxhumana ezikude.
I-collimator elungisekayo ye-RCF15x-P01 ingafakwa ku-slip ye-SM1RC(/M)indandatho noma i-SM1TC sleeve clamp usebenzisa ingxenye emnyama.
Ukuze kulungiswe iphimbo/ukugoba, kunconywa ukusebenzisa i-Polaris mount, njengei-POLARIS-K2 noma i-POLARIS-K2VS2L Ø2" kinematic mount isebenzisa i-AD2Ti-adaptha; i-POLARIS-K2T SM2-threaded kinematic mount esebenzisa i-SM2A21i-adaptha; noma i-POLARIS-K15XY 5-axis kinematic mount usebenzisa i-SM1L03ishubhu yelensi kanye ne-adaptha ye-SM1A68.
Ukuphela kwesikhala esikhululekile sendlu ye-collimator elungisekayo kufakwe uchungechungeimicu ye-SM05 yangaphakathi kanye neyangaphandle ye-SM1.
Izibonelo zokufaka i-collimatorziboniswe kulezi zithombe ezimbili ezilandelayo.
Ukuhlanganiswa Kwefayibha Yemodi Eyodwa
Lapho kuhlanganiswa imicu yemodi eyodwa, lawa ma-collimator abonakalisayo akhiqiza ububanzi-isinqe, imisebe ephambuka kancane.
Ukuhlukana okuphelele komsebe ohlanganisiwe (ngamadigri) kungalinganiswaububanzi bensimu yemodi ye-fiber (MFD) kanye nobude be-reflector focal (RFL):
Ububanzi obuyi-1/e² bomsebe ohlanganisiwe cishe buyi:
Isibonelo, ukusebenzisa i-RCR25A-P01 small collimator ukuze kuhlanganiswe i-P3-I-fiber yemodi eyodwa engu-630A-FC-1, enobude be-λ = 633 nm, i-MFD ingu-4.3µm.
Izibalo ezimbili ezingenhla zibonisa ukuthi i-engeli yokwehlukana ingu-0.01 degrees, futhi ububanzi bomsebe bungu-4.8 mm.
Ukuhlanganiswa Kwefayibha Yamamodi Amaningi
I-engeli yokuhlukana iyonke yomsebe ohlanganisiwe cishe ilandelayo:
Ububanzi bomsebe we-collimated cishe buyi:
Umphumela we-fiber ye-multimode ngokuvamile awuhlanganiswa kahle.
Ngokusho kwefomula engenhla, ububanzi bomsebe buthinteka kakhulu yi-NAendaweni eseduze ne-OAP reflector, kodwa njengoba umsebe usakazeka,Ithonya lobubanzi obuyinhloko liba sobala kakhulu.
Kwi-collimator ehleliwe okukhulunywe ngayo ngenhla, ububanzi be-collimated beam buyikubalwe nge-2NA*RFL, okungaphezu kobubanzi bebhamu eli-1/e².
Uma ukhetha i-collimator engaguquki, ubude be-focal bungatholakala kusukela ku-ububanzi bomsebe obudingekayo ukuze kunqunywe imodeli efanele.
Kunemikhawulo emibili ebalulekile ekuhlanganiseni imicu ye-multimode.
Okokuqala, imicu eminingi ye-multimode inomsebe wokukhipha ohlukile kakhulu ongabaivinjiwe yindlu ngaphambi kokufinyelela ku-OAP reflector, ngakho-ke i-fiber NAayikwazi ukudlula inani elithile; bheka ithebula elidlule ukuthola imininingwane.
Okwesibili, ukwehluka komsebe we-collimated kuhlobene nomongoububanzi; njengoba ububanzi obuyinhloko bukhula, i-NA ephezulu esekelwa yii-collimator iyancipha.
Uma ububanzi bomsebe ohlanganisiwe budlula imbobo ecacile, umphumelaugongolo luzovinjelwa yindlu.
Zombili lezi zimo zingaholela ekwehleni kwekhwalithi yemisebe.
Ngaphezu kwalokho, izibonisi ze-OAP zingalinganisa ngokuphelele imithombo yamaphuzu ku-iphuzu elibalulekile.
Uma ukuphambuka komthombo wamaphuzu kusuka ku-axis ye-optical kukhulu, nomaubukhulu bomnyombo wemodi eminingi bukhudlwana, kulapho ukuphambuka kwe-collimated kukhulu khonaugongolo; ukwandisa ubude be-reflection focal noma ubude be-wavelength kunganciphisaukuhlanekezela.
