I-Thorlabs reflective fiber collimator isekelwe kwisibuko se-90 ° off-axis paraboloid (OAP) esinobude obugxininise obuthe gqolo kuluhlu olubanzi lwamaza kwaye ilungele ukusetyenziswa kwiinkqubo ezifuna ukungqubana kwamaza amaninzi.
I-collimator ebonakalisayo ifumaneka kwizakhiwo ezintathu zezindlu, nganye ihambelana ne-fiber jumpers kunye ne-FC / PC, FC / APC, okanye i-SMA connectors.
Iziseko ze-OAP Reflector
I-OAP(Off-Axis Parabolic) Isibonisi yinxalenye yomzali wayo weparabolic.
I-off-axis ithetha ukuba ii-axes zokubona zombini zihambelana kodwa azingqamananga.
I-axis ekugxilwe kuyo idlula embindini wengqwalasela kunye ne-OAP Reflector,kwaye umgama phakathi kwala manqaku mabini ubizwa ngokuba bubude bojoliso obubonakalisiweyo(RFL).
I-engile phakathi kwe-axis yokugxila kunye ne-optical axis yi-Angle ye-off-axis,eli 90 degrees apha.
Fixed Collimator
Iifiber collimators ezizinzileyo zibonelela ngeefilimu ezimbini zentsimbi ezibonisa okuphezulu: -F01 UV-ifilimu ye-aluminiyam ephuculweyo kunye nefilimu yesilivere ye-P01 enomgangatho okhuselayo, ezikucetyiswa kwimowudi enye kunye nemultimode fiber collimation kunyeizicelo zokudibanisa ifayibha ezininzi.
Ngokwe-collimated beam diameter (ye-0.13 NA ifayibha), banokubayahlulwe kolu luhlu lune lulandelayo:
Imifanekiso emine engentla apha RC02FC-P01, RC04FC-P01, RC08APC-P01 kunyeRC12SMA-P01 ngokulandelelanayo.
Ngoko ke, ngokwemodeli yemveliso, sinokuyazi iiparamitha eziphambiliyecollimator nganye ebonakalisayo, kuqukwa nedayamitha ye-collimated beam, ifayibhaisinxibelelanisi kunye nokwaleka.
I-RC02, RC04, kunye ne-RC08 collimators ziyahambelana ne-SM05- yangaphakathi.izinyusi ezinemisonto, ngelixa i-RC12 icollimator iyahambelana ne-SM1- yangaphakathi.izinyusi ezinemisonto.
Ukongeza, i-RC02 collimator inokugxunyekwa ngokuthe ngqo kwi-Ø1/2"i-kinematic mount, ngelixa i-RC02, i-RC04, kunye ne-RC08 inokunyuswa ngokuthe ngqokwi Ø1" intaba yekinematic (emva kokuqala ukukhulula umsesane ojuliweyo simahlaizibuko lendawo);
Ukunyuka nge-kinematic mount iququzelela ukulungelelaniswa kwe-beam xa ukudibanisa i-fiberIyafuneka.
I-Collimator encinci
I-collimator encinci ifezekisa uyilo oluncinci ngokuba nesibonisi kwiicala elichaseneyo ukuya ngaphambili. Inokwahlulwa ibe ziichungechunge ezimbini ngokweUbude bokujolisa: RCR25x-P01 kunye ne-RCR50x-P01, kunye nobude bokujolisaye-25.4 kunye ne-50.8 mm ngokulandelelanayo; i-x kwimodeli yenani lusingauhlobo lwesidibanisi, esinokufakwa endaweni ye-P, A kunye no-S ukumela iFC/PC,I-FC / APC kunye nezixhumi ze-SMA ngokulandelanayo.
Ii-collimators ezincinci zinokunyuswa ngokuthe ngqo kwi-Ø1/2" ii-lens tube mounts, ezinjalonjenge-SM05RC(/M) slip ring kunye ne-SM05TC clamp.
Ukuba i-pitch/yaw uhlengahlengiso luyafuneka, zinokuxhonywa kwi-Ø1" kinematicnyuka usebenzisa i-adapter ye-SM1A60.
I-collimator encinci ingaphinda idibaniswe ngokuthe ngqo kwi-cage ye-16 mminkqubo esebenzisa ipleyiti yekheji ye-SP3 okanye i-SC6W yekheji ityhubhu, okanye ibe yi-30 mminkqubo ye-cage usebenzisa i-adapter ye-SM1A60 kunye ne-cube ye-C4W ye-cage.
I-Collimator ehlengahlengiswayo
Ii-collimators ezihlengahlengiswayo zinokuhlengahlengisa umgama ukusuka kwifayibha ukuya kwisibuko se-OAP ukwandisa ukungqubana kwefayibha nganye okanye ukudibanisa ukukhanya kwi-singlemode okanye i-multimode fibers.
Xa umgca obhaliweyo uhambelana nesimboli ∞, umgama ukusuka kwifayibhaukuya OAP reflector ilingana RFL, kwaye iziphumo collimator aumqadi odityanisiweyo (ngasentla).
Xa umgca obhaliweyo utenxa kwisimboli ∞, i-collimator ikhupha aumqadi ohlukeneyo okanye oguquguqukayo, kunye nomgama ophezulu ukusuka ekugxilweni kwawo ukuyaUmbindi wesibonisi yi-2.2 m kunye ne-0.15 m, ngokulandelelanayo, njengoko kubonisiwekulandela amanani amabini.
Xa umlinganiselo we-conjugate ulingana nokungapheliyo, izibuko ze-OAP zinokufikeleladiffraction-umda womfanekiso.
Njengoko kubonisiwe kulo mzobo ungezantsi, ii-collimators ezimbini ezilungelelanisiweyo zikwakhonailungele kakhulu ukudibanisa umgama omde, ukuze indawo ephakathi yasimahlaUmqadi unokuqhutywa kunye nezinye izinto ezibonakalayo, eziluncedo kakhulu kwiizicelo zonxibelelwano olude.
I-RCF15x-P01 i-collimator ehlengahlengiswayo inokuxhonywa kwisiliphu se-SM1RC(/M)iringi okanye i-SM1TC sleeve clamp usebenzisa icandelo elimnyama.
Ukulungiswa kwe-pitch / yaw, kuyacetyiswa ukuba usebenzise intaba ye-Polaris, efanai POLARIS-K2 okanye POLARIS-K2VS2L Ø2" intaba yekinematic usebenzisa iAD2Tiadaptha Intaba ye-POLARIS-K2T SM2 enemisonto enemisonto usebenzisa i-SM2A21iadaptha okanye i-POLARIS-K15XY 5-axis kinematic mount usebenzisa i-SM1L03ityhubhu ye-lens kunye ne-adapter ye-SM1A68.
Isiphelo sendawo yasimahla yendlu ye-collimator ehlengahlengiswayo ifakwe ngentamboi-SM05 yangaphakathi kunye nemisonto ye-SM1 yangaphandle.
Imizekelo yokufaka i-collimatorziboniswe kule mizobo mibini ilandelayo.
IMode Eyodwa yeFayibha Collimation
Xa zidibanisa iintsinga zemowudi enye, ezi collimators ziveza imveliso ebanzi-esinqeni, imiqadi yokwahlukana okuphantsi.
Ukuhlukana okupheleleyo kwe-collimated beam (ngeedigri) kunokuqikelelwangedayamitha yommandla wefayibha (MFD) kunye nobude bojoliso lwesibonisi (RFL):
I-1/e² yedayamitha yomqadi odityanisiweyo imalunga:
Umzekelo, ukusebenzisa i-RCR25A-P01 i-collimator encinci ukungqubana ne-P3-I-630A-FC-1 i-fiber yemowudi enye, kwi-wavelength ye-λ = 633 nm, i-MFD yi-4.3µm.
Ezi equations zimbini zingasentla zibonisa ukuba i-divergence angle yi-0.01 degrees, kunye ne-diameter ye-boam yi-4.8 mm.
I-Multimode Fiber Collimation
Itotali yokwahlukana kwe-engile yomqadi odityanisiweyo imalunga:
Ubukhulu bomqadi odityanisiweyo bumalunga:
Imveliso yefiber ye-multimode ayiqhelekanga ukuba idibanise kakuhle.
Ngokwale fomyula ingentla, i-diameter ye-beam ichaphazeleka kakhulu yi-NAkwindawo ekufutshane ne-OAP reflector, kodwa njengoko umqadi usasaza, iImpembelelo yedayamitha engundoqo iba ngakumbi nangakumbi.
Kwi-collimator esisigxina ekhankanywe ngasentla, i-diameter ye-collimated beam iibalwa nge-2NA*RFL, enkulu kuno-1/e² umqadi wedayamitha.
Xa ukhetha i-collimator esisigxina, ubude obugxilwe bunokuthi buthathwe kwi-efunekayo umqadi ukumisela imodeli efanelekileyo.
Kukho imida emibini ebalulekileyo ekudibaniseni imicu yemultimode.
Okokuqala, uninzi lweentsinga zemultimode zinemiqadi eyahlukeneyo enokubakhoivalwe yindlu ngaphambi kokufikelela kwi-OAP reflector, ngoko ke i-fiber NAayinakugqitha kwixabiso elithile; bona itheyibhile engaphambili ngeenkcukacha.
Okwesibini, ukuhlukana kwe-beam edibeneyo kuhambelana nengundoqoububanzi; njengoko i-diameter engundoqo isanda, i-NA ephezulu ixhaswa yii-collimator iyancipha.
Ukuba i-diameter ye-collimated beam idlula i-aperture ecacileyo, umphumoUmqadi uya kuvalelwa yindlu.
Zombini ezi meko zinokukhokelela ekunciphiseni umgangatho we-beam.
Ukongeza, izibonisi ze-OAP zinokudibana ngokugqibeleleyo kwimithombo yeendawoIndawo yokujonga.
Okukhona ukutenxa kumthombo wenqaku ukusuka kwi-optical axis, okanye iUbukhulu be-multimode core diameter, okukhulu ukugqwesa kwe-collimatedumqadi ukwandisa ubude bojoliso bembonakalo okanye ubude bomza kunokunciphisauphazanyiso.
