I-Thorlabs reflective fiber collimator isekelwe kwisibuko se-90°off-axis paraboloid (OAP) esinobude obungaguqukiyo kuluhlu olubanzi lwamaza kwaye ifanelekile ukusetyenziswa kwiinkqubo ezifuna i-collimation yamaza amaninzi.
I-reflective collimator ifumaneka kwiidizayini ezintathu zezindlu, nganye ihambelana nee-fiber jumpers ezine-FC/PC, FC/APC, okanye ii-SMA connectors.
Iziseko ze-OAP Reflector
I-OAP (Off-Axis Parabolic) Reflector yinxalenye ye-parabolic yayo engumzali.
I-Off-axis ithetha ukuba ii-optical axes zezi zimbini ziyafana kodwa azihambelani.
I-focus axis idlula embindini we-focus kunye ne-OAP Reflector,kwaye umgama phakathi kwezi ngongoma zimbini ubizwa ngokuba yi-reflective focal length(i-RFL).
I-engile ephakathi kwe-focus axis kunye ne-optical axis yi-off-axis Angle,eliyi-90 degrees apha.
I-Collimator Ezinzileyo
Ii-collimators zefayibha ezizinzileyo zibonelela ngeefilimu ezimbini zesinyithi ezibonisa ukukhanya okuphezulu: -F01 UV-ifilimu ye-aluminium ephuculweyo kunye nefilimu yesilivere ye-P01 enomaleko okhuselayo, eziKucetyiswa ukuba kubekho i-single-mode kunye ne-multimode fiber collimation kunyeusetyenziso lokudibanisa ifayibha ye-multimode.
Ngokwe-collimated beam diameter (ye-0.13 NA fiber), zinokubayahlulwe ngolu luhlu lune lulandelayo:
Imifanekiso emine engasentla yi-RC02FC-P01, RC04FC-P01, RC08APC-P01 kunyeRC12SMA-P01 ngokwahlukeneyo.
Ngoko ke, ngokwemodeli yemveliso, singazazi iiparameter eziphambiliye-collimator nganye ebonakalisayo, kuquka ububanzi be-collimated beam, i-fiberisinxibelelanisi kunye nokwaleka.
Ii-collimators ze-RC02, RC04, kunye ne-RC08 ziyahambelana ne-SM05- yangaphakathiii-threaded mounts, ngelixa i-RC12 collimator ihambelana ne-SM1- yangaphakathiizikhonkwane ezinemisonto.
Ukongeza, i-RC02 collimator ingafakelwa ngqo kwi-Ø1/2"i-kinematic mount, ngelixa i-RC02, i-RC04, kunye ne-RC08 zinokufakelwa ngqokwi-Ø1" kinematic mount (emva kokukhulula indandatho eqhiniweyo kwi-freeizibuko lesithuba);
Ukufakela nge-kinematic mount kwenza kube lula ukulungelelaniswa kwemitha xa kudityaniswa ifayibhaIyafuneka.
I-Collimator encinci
I-collimator encinci ifumana uyilo oluncinci ngokuba ne-reflector kwiicala elichaseneyo nelangaphambili. Ingahlulwa ibe ziichungechunge ezimbini ngokweubude befocal: RCR25x-P01 kunye ne-RCR50x-P01, kunye nobude befocal bokubonakalisaye-25.4 kunye ne-50.8 mm ngokulandelelana; u-x kwinombolo yemodeli yifayibhauhlobo lwesixhumi, esinokutshintshwa ngo-P, A kunye no-S ukuze zimele i-FC/PC,Izihlanganisi zeFC/APC kunye neSMA ngokwahlukeneyo.
Ii-collimators ezincinci zinokufakelwa ngqo kwii-lens tube mounts ze-Ø1/2", ezifananjengeringi yokutyibilika ye-SM05RC(/M) kunye ne-SM05TC clamp.
Ukuba kufuneka ukulungiswa kwepitch/yaw, zinokufakelwa kwi-kinematic ye-Ø1"faka usebenzisa iadaptha ye-SM1A60.
I-collimator encinci ingafakwa ngqo kwikheyiji eyi-16 mminkqubo esebenzisa ipleyiti yekheyiji ye-SP3 okanye ityhubhu yekheyiji ye-SC6W, okanye kwi-30 mminkqubo yekheji esebenzisa iadaptha ye-SM1A60 kunye netyhubhu yekheji ye-C4W.
I-Collimator ehlengahlengiswayo
Ii-collimators ezilungisekayo zinokulungisa umgama ukusuka kwifayibha ukuya kwisibuko se-OAP ukuze kuphuculwe i-collimation yefayibha nganye okanye ukudibanisa ukukhanya kube yi-singlemode okanye ii-multimode fibers.
Xa umgca obhaliweyo uhambelana nophawu lwe-∞, umgama ukusuka kwifayibhakwi-OAP reflector ilingana ne-RFL, kwaye i-collimator ikhupha i-umqadi oqokelelweyo (ngasentla).
Xa umgca obhaliweyo uphambuka kwisimboli ye-∞, i-collimator ikhupha i-umqadi ohlukeneyo okanye odibeneyo, kunye nomgama ophezulu ukusuka ekugxilweni kwawo ukuyaumbindi wesibonisi yi--2.2 m kunye ne-0.15 m, ngokulandelelana, njengoko kubonisiwe kwikulandela imifanekiso emibini.
Xa i-conjugate ratio ilingana ne-infinity, izibuko ze-OAP zinokufikelelaimifanekiso enomda wokuphambuka.
Njengoko kubonisiwe kumfanekiso ongezantsi, kukho ii-collimators ezimbini ezihlengahlengiswayo nezibonakalayoifanelekile kakhulu ekudibaneni umgama omde, ukuze indawo ephakathi ekhululekileyoumqadi ungalawulwa nezinye izinto ezibonakalayo, nto leyo eluncedo kakhuluizicelo zonxibelelwano olukude.
I-RCF15x-P01 adjustable collimator inokufakelwa kwi-SM1RC(/M) slipiringi okanye i-SM1TC sleeve clamp usebenzisa icandelo elimnyama.
Ukuze ulungise iphimbo/ukuhla, kuyacetyiswa ukuba usebenzise isixhobo sokukhwelisa iPolaris, esifanai-POLARIS-K2 okanye i-POLARIS-K2VS2L Ø2" kinematic mount isebenzisa i-AD2Tiadaptha; i-POLARIS-K2T SM2-threaded kinematic mount esebenzisa i-SM2A21iadaptha; okanye i-POLARIS-K15XY 5-axis kinematic mount usebenzisa i-SM1L03ityhubhu yelensi kunye neadaptha ye-SM1A68.
Isiphelo sendawo ekhululekileyo sendlu ye-collimator ehlengahlengiswayo sifakwe imisontoimisonto ye-SM05 yangaphakathi kunye neyangaphandle ye-SM1.
Imizekelo yokufakela i-collimatorziboniswe kwimifanekiso emibini elandelayo.
Ukuhlanganiswa kweFiber yeModi enye
Xa kuhlanganiswa iifayibha zemowudi enye, ezi collimators ezibonisa ukukhanya zivelisa ububanzi-isinqe, imiqadi engaphantsi komahluko.
Ukwahlukana okupheleleyo kwe-collimated beam (kwii-degrees) kunokuqikelelwaububanzi bentsimi ye-fiber mode (MFD) kunye nobude be-reflector focal (RFL):
Ububanzi be-1/e² bomqadi odibeneyo bumalunga ne:
Umzekelo, ukusebenzisa i-RCR25A-P01 small collimator ukuhlanganisa i-P3-Ifayibha yemowudi enye ye-630A-FC-1, kubude be-λ = 633 nm, i-MFD yi-4.3µm.
Ezi zibalo zimbini zingasentla zibonisa ukuba i-engile yokwahlukana yi-0.01 degrees, kwaye ububanzi bomqadi yi-4.8 mm.
Ukuhlanganiswa kweFiber yeMode ezininzi
I-engile iyonke yokwahlukana komqadi odibeneyo imalunga ne:
Ububanzi bomqadi we-collimated bumalunga ne:
Imveliso ye-multimode fiber ayisoloko ihlanganiswa kakuhle.
Ngokwefomula engentla, ububanzi bomqadi buchaphazeleka kakhulu yi-NAkwindawo ekufutshane ne-OAP reflector, kodwa njengoko umqadi usasazeka,Impembelelo yobubanzi obuphambili iba yinto ecacileyo ngakumbi nangakumbi.
Kwi-collimator esisigxina ekhankanyiweyo apha ngasentla, ububanzi be-collimated beam buyiibalwe yi-2NA*RFL, engaphezulu kwe-1/e² ububanzi bomqadi.
Xa ukhetha i-collimator esisigxina, ubude be-focal bunokuqikelelwa ukusuka kwiububanzi bomqadi obufunekayo ukuze kuchongwe imodeli efanelekileyo.
Kukho imida emibini ebalulekileyo ekuhlanganiseni iifayibha ze-multimode.
Okokuqala, uninzi lwee-fibers ze-multimode zine-output beam eyahlukileyo kakhulu enokubaivalwe yindlu ngaphambi kokuba ifikelele kwi-OAP reflector, ngoko ke i-fiber NAayinakudlula ixabiso elithile; jonga itheyibhile yangaphambili ukuze ufumane iinkcukacha.
Okwesibini, umahluko we-collimated beam unxulumene nombindiububanzi; njengoko ububanzi obuphambili bukhula, i-NA ephezulu exhaswa yii-collimator iyancipha.
Ukuba ububanzi bomqadi oqokelelweyo budlula umngxuma ocacileyo, imvelisoumqadi uya kuvinjelwa yindlu.
Zombini ezi meko zinokubangela ukuba umgangatho wemitha unciphe.
Ukongeza, ii-reflectors ze-OAP zinokulinganisa ngokugqibeleleyo kuphela imithombo yeengongoma kwiIndawo yokujonga.
Okukhona ukuphambuka komthombo wenqaku ukusuka kwi-optical axis, okanyeubukhulu be-multimode core diameter, kokukhona ukugqwetheka kwe-collimated kukhuluumqadi; ukwandisa ubude be-reflection focal okanye ubude be-wavelength kunokunciphisauphazanyiso.
