Thorlabs reflective fiber collimator yakavakirwa pagirazi re90°off-axis paraboloid (OAP) rine urefu hwakasimba hwefocal pamusoro pehuwandu hwakakura hwewavelength uye rakanakira kushandiswa mumasisitimu anoda collimation yema wavelengths akawanda.
Iyo reflective collimator inowanikwa mumhando nhatu dzemahombe, imwe neimwe inoenderana nemafiber jumpers ane FC/PC, FC/APC, kana SMA connectors.
Nheyo dzeOAP Reflector
OAP (Off-Axis Parabolic) Reflector chikamu cheparabolic yayo huru.
Off-axis zvinoreva kuti ma optical axes maviri aya akafanana asi haasi masanga.
Mutsetse wekutarisa unopfuura nepakati pekutarisa uye OAP Reflector,uye daro riri pakati penzvimbo mbiri idzi rinonzi kureba kwenzvimbo dzakaratidzwa(RFL).
Angle iri pakati pe focusing axis ne optical axis ndiyo Angle iri off-axis,inova madhigirii makumi mapfumbamwe pano.
Collimator Yakagadziriswa
Fixed fiber collimators inopa mafirimu maviri esimbi anonyatsoratidza chiedza: -F01 UV-firimu realuminium rakagadziriswa uye firimu resirivha re -P01 rine jira rinodzivirira, izvo zviriinokurudzirwa kune single-mode uye multimode fiber collimation uyemashandisirwo ekubatanidza fiber ye multimode.
Zvichienderana nedhayamita yedanda re collimated (ye 0.13 NA fiber), dzinogona kuvayakakamurwa kuita zvikamu zvina zvinotevera:
Mifananidzo mina iri pamusoro apa ndeiyi RC02FC-P01, RC04FC-P01, RC08APC-P01 uyeRC12SMA-P01 zvichiteerana.
Saka, zvichienderana nemuenzaniso wechigadzirwa, tinogona kuziva ma parameter makuruye collimator imwe neimwe inoratidza, kusanganisira dhayamita ye collimated beam, fiberchinobatanidza uye chifukidziro.
Macollimator eRC02, RC04, uye RC08 anoenderana neSM05- yemukatizvinosungirirwa zvine tambo, nepo RC12 collimator inoenderana neSM1- yemukatizvigadziko zvakarukwa.
Pamusoro pezvo, RC02 collimator inogona kuiswa zvakananga mu Ø1/2"kinematic mount, nepo RC02, RC04, uye RC08 zvichigona kuiswa zvakanangamuchikamu che Ø1" kinematic mount (mushure mekusunungura mhete yakakoshwa kekutanga pa freechiteshi chemuchadenga);
Kuisa chisimbiso chekinematic kunoita kuti danda rienderane kana fiber yakabatana.chinodiwa.
Collimator Diki
Kabhodhi kadiki kanoita dhizaini yakatetepa nekuisa chiratidziri mukatidivi rakatarisana nemberi. Rinogona kukamurwa kuita zvikamu zviviri zvichienderana nekureba kwefocal: RCR25x-P01 uye RCR50x-P01, nehukuru hwefocal hwe reflectionye25.4 uye 50.8 mm zvichiteerana; x iri munhamba yemuenzaniso ndiyo fiberrudzi rwechinobatanidza, chinogona kutsiviwa neP, A naS kumiririra FC/PC,Zvinobatanidza zveFC/APC neSMA zvakateerana.
Makolimata madiki anogona kuiswa zvakananga muma Ø1/2" lens tube mounts, akadai sese SM05RC(/M) slip ring uye SM05TC clamp.
Kana zvichidikanwa kugadzirisa pitch/yaw, zvinogona kuiswa mu Ø1" kinematicisa uchishandisa adapta yeSM1A60.
Kamuchina kadiki ke collimator kanogonawo kubatanidzwa zvakananga mukeji ine 16 mmuchishandisa ndiro yeSP3 cage kana SC6W cage cube, kana kuti mu30 mmsisitimu yekeji uchishandisa adapta yeSM1A60 uye cube yekeji yeC4W.
Collimator Inogadziriswa
Macollimator anogadziriswa anogona kugadzirisa daro kubva pafiber kuenda kuOAP mirror kuti agadzirise collimation yefiber yega yega kana kubatanidza chiedza kuita singlemode kana multimode fibers.
Kana mutsetse wakanyorwa wakabatana nechiratidzo che∞, daro kubva pafiberkuOAP reflector yakaenzana neRFL, uye collimator inoburitsa adanda rakaumbwa (pamusoro).
Kana mutsetse wakanyorwa ukatsauka kubva pachiratidzo che ∞, collimator inoburitsa adanda rakasiyana kana kuti rinobatana, uye daro guru kubva pakutarisisa kwaro kuendaPakati pechiratidziro pane -2.2 m uye 0.15 m, zvichiteerana, sezvakaratidzwa muvachitevera mifananidzo miviri.
Kana chiyero che conjugate chakaenzana ne infinity, magirazi eOAP anogona kuitamifananidzo ine diffraction shoma.
Sezvakaratidzwa mumufananidzo uri pazasi, ma collimator maviri anogadzirisika anoratidzwawoyakakodzera kwazvo kubatanidza kure, kuitira kuti nzvimbo yepakati yakasununguka ivedanda rinogona kutungamirirwa nezvimwe zvinhu zve optical, izvo zvinobatsira zvikurumashandisirwo ekutaurirana ari kure.
Iyo RCF15x-P01 inogadziriswa collimator inogona kuiswa muSM1RC(/M) slipmhete kana chibatiso chesleeve cheSM1TC uchishandisa chikamu chitema.
Kuti ugadzirise pitch/yaw, zvinokurudzirwa kushandisa Polaris mount, yakaita sechinhu chinosungirirwa chePOLARIS-K2 kana POLARIS-K2VS2L Ø2" uchishandisa AD2Tadapta; iyo POLARIS-K2T SM2-threaded kinematic mount ichishandisa SM2A21adapta; kana POLARIS-K15XY 5-axis kinematic mount uchishandisa SM1L03chubhu yelenzi uye adapta yeSM1A68.
Mugumo wenzvimbo yakasununguka weimba ye collimator inogadziriswa une tambotambo dzemukati dzeSM05 nedzekunze dzeSM1.
Mienzaniso yekugadzika collimatorzvinoratidzwa mumifananidzo miviri inotevera.
Kuunganidzwa kweFiber yeModhi Imwe Chete
Pakusanganisa mafiber emhando imwe chete, ma collimator aya anogadzira zvinhu zvakasiyana-siyana-chiuno, matanda asina kupatsanurwa zvakanyanya.
Kusiyana kwese kwedanda re collimated (mumadhigirii) kunogona kufungidzirwanedhayamita yemunda wefiber mode (MFD) uye urefu hwe reflector focal (RFL):
Dhayamita ye 1/e² ye collimated beam inenge:
Semuenzaniso, kushandisa RCR25A-P01 small collimator kuenzanisa P3-630A-FC-1 single-mode fiber, pahurefu hwe λ = 633 nm, MFD i4.3µm.
Maequation maviri ari pamusoro apa anoratidza kuti kona yekusiyana i 0.01 degrees, uye dhayamita yedanda iri 4.8 mm.
Kubatanidzwa kweFiber yeMultimode
Kona yekusiyana kwese kwedanda re collimated inenge iri:
Dhayamita yedanda re collimated inenge iri:
Kubuda kwefiber ye multimode kazhinji hakunyatso sanganiswa zvakanaka.
Zvichienderana nefomura iri pamusoro apa, dhayamita yedanda inonyanya kukanganiswa neNApanzvimbo iri pedyo neOAP reflector, asi sezvo danda richipararira,simba redhayamita repakati rinowedzera kuoneka.
Kune collimator yakagadziriswa yataurwa pamusoro apa, dhayamita yedanda re collimated ndiyoyakaverengerwa ne2NA*RFL, iyo inopfuura dhayamita yedanda re1/e².
Pakusarudza fixed collimator, focal length inogona kuverengerwa kubva padhayamita yedanda inodiwa kuti uone modhi yakakodzera.
Pane zvipingamupinyi zviviri zvakakosha pakugadzira mafiber e multimode.
Chekutanga, mafiber mazhinji e multimode ane dayamondi rinobuda rakasiyana zvikuru rinogona kuburitswayakavharirwa neimba isati yasvika paOAP reflector, saka fiber NAhaigone kudarika kukosha kwakati; ona tafura yapfuura kuti uwane rumwe ruzivo.
Chechipiri, kusiyana kwedanda re collimated kwakabatana nepakatidhayamita; sezvo dhayamita yepakati ichiwedzera, iyo NA yepamusoro inotsigirwa necollimator inoderera.
Kana dhayamita yedanda re collimated ikapfuura aperture yakajeka, kubuda kwayodanda richavharwa neimba yacho.
Mamiriro ese ari maviri aya anogona kukonzera kudzikira kwemhando yemwaranzi.
Pamusoro pezvo, maOAP reflectors anogona chete kuenzanisa zvakakwana mapoinzi ari panzvimbo yekutarisa.
Kutsauka kukuru kwenzvimbo inobva pa optical axis, kana kutiyakakura dhayamita yepakati ye multimode, ndiko kukura kwekukanganiswa kwe collimatedkuwedzera urefu hwe reflection kana wavelength kunogona kuderedzakukanganiswa.
