Iyo Thorlabs reflective fiber collimator yakavakirwa pachionioni che90 ° off-axis paraboloid (OAP) ine nguva dzose yakatarisa kureba pamusoro pehupamhi hwewavelength renji uye yakanakira kushandiswa mumasisitimu anoda kudhumhana kweakawanda mawavelength.
Iyo inoratidzira collimator inowanikwa mumatatu edzimba dhizaini, imwe neimwe inoenderana nefiber jumpers neFC/PC, FC/APC, kana SMA zvibatanidza.
Basics Of OAP Reflector
OAP(Off-Axis Parabolic) Reflector chikamu chemubereki wayo parabolic.
Off-axis zvinoreva kuti maaxisi ekuona paaviri aya anoenderana asi haana masangana.
Iyo yekutarisa axis inopfuura nepakati pekutarisa uye iyo OAP Reflector,uye chinhambwe chiri pakati pezvibodzwa zviviri izvi chinodaidzwa kuti hurefu hwakatariswa hwakatariswa(RFL).
Iyo Angle iri pakati peiyo yakatarisa axis uye yekuona axis ndiyo off-axis Angle,iyo iri 90 degrees pano.
Fixed Collimator
Fixed fiber collimators inopa maviri akakwira anotaridza simbi mafirimu: -F01 UV-yakagadziridzwa aluminium firimu uye -P01 sirivheri firimu ine inodzivirira layer, ayo ariinokurudzirwa kune imwe-modhi uye multimode fiber collimation uyemultimode fiber coupling application.
Zvinoenderana neiyo collimated danda dhayamita (ye0.13 NA faibha), vanogona kuvayakakamurwa kuita mana anotevera akatevedzana:
Mifananidzo mina iri pamusoro ndeye RC02FC-P01, RC04FC-P01, RC08APC-P01 uyeRC12SMA-P01 zvichiteerana.
Nokudaro, maererano nemuenzaniso wechigadzirwa, tinogona kuziva maitiro makuruyeimwe neimwe inoratidzira collimator, kusanganisira collimated danda dhayamita, faibhaconnector uye coating.
Iyo RC02, RC04, uye RC08 collimators inoenderana nemukati SM05-akarukwa makomo, nepo RC12 collimator inoenderana nemukati SM1-threaded mounts.
Mukuwedzera, iyo RC02 collimator inogona kukwidziridzwa yakananga muØ1/2"kinematic gomo, nepo RC02, RC04, uye RC08 inogona kupera-yakaiswa zvakanangamu Ø1" kinematic gomo (mushure mekutanga kusunungura mhete yakarukwa pane yemaharanzvimbo port);
Kukwira ne kinematic gomo kunofambisa kurongeka kwedanda kana fiber yakabatanazvinodiwa.
Diki Collimator
Iyo diki collimator inowana dhizaini dhizaini nekuva nereflector mukwakatarisana nekumberi. Inogona kukamurwa kuita maviri akatevedzana maereranoiyo yakatarisa kureba: RCR25x-P01 uye RCR50x-P01, ine kutarisisa kurebaye25.4 uye 50.8 mm zvichienderana; iyo x iri mumuenzaniso nhamba ndiyo fiberyekubatanidza mhando, inogona kutsiviwa neP, A uye S kumiririra FC/PC,FC/APC uye SMA zvinongedzo zvichiteerana.
Madiki macollimator anogona kukwidzwa akananga muØ1/2" lens tube mounts, akadaise SM05RC(/M) inotsvedza mhete uye SM05TC simbi.
Kana pitch/yaw gadziriso ichidikanwa, inogona kuiswa muØ1" kinematicgomo uchishandisa iyo SM1A60 adapta.
Iyo diki collimator inogona zvakare kubatanidzwa zvakananga mune 16 mm kejisystem inoshandisa SP3 cage plate kana SC6W cage cube, kana kupinda 30 mmcage system inoshandisa SM1A60 adapta uye C4W cage cube.
Adjustable Collimator
Macollimator anochinjika anogona kugadzirisa chinhambwe kubva pafayibha kuenda kuchionioni cheOAP kukwenenzvera kudhumhana kwefayibha yega yega kana kuti kubatanidza mwenje kuita singlemode kana multimode fibers.
Kana mutsara wakanyorwa uchienderana ne ∞ chiratidzo, chinhambwe kubva kune fiberkuOAP reflector yakaenzana neRFL, uye collimator inobuda acollimated beam (pamusoro).
Kana mutsara wakanyorwa watsauka kubva pane ∞ chiratidzo, collimator inoburitsa adivergent kana convergent danda, uye kureba kwechinhambwe kubva pakutarisa kwacho kuendapakati pechiratidziri -2.2 m uye 0.15 m, zvichiteerana, sezvakaratidzwa muachitevera manhamba maviri.
Kana iyo conjugate ratio yakaenzana nekusingaperi, magirazi eOAP anogona kuwanadiffraction-limited imaging.
Sezvinoratidzwa mumufananidzo uri pazasi, maviri anochinjika anoratidza collimator ari zvakareyakanyatsokodzera kubatanidza kure-kure, kuitira kuti yepakati yakasununguka-nzvimbodanda rinogona kutungamirwa nezvimwe zvinhu zvemaziso, izvo zvinobatsira zvakanyanya mukatimaapplication ekutaura kure kure.
Iyo RCF15x-P01 inogadziriswa collimator inogona kuiswa muSM1RC(/M) inotsvedza.mhete kana SM1TC sleeve clamp uchishandisa chikamu chitema.
Nekugadziriswa kwepitch / yaw, zvinokurudzirwa kushandisa gomo rePolaris, sengeiyo POLARIS-K2 kana POLARIS-K2VS2L Ø2" kinematic gomo uchishandisa iyo AD2Tadapta; iyo POLARIS-K2T SM2-yakarukwa kinematic gomo uchishandisa iyo SM2A21adapta; kana iyo POLARIS-K15XY 5-axis kinematic gomo uchishandisa iyo SM1L03lens chubhu uye SM1A68 adapta.
Iyo yemahara-nzvimbo yekupedzisira yeinogadziriswa collimator imba yakarukwa nayoyemukati SM05 uye ekunze SM1 shinda.
Mienzaniso yekuisa collimatorzvinoratidzwa mumifananidzo miviri inotevera.
Single Mode Fiber Collimation
Pakukochekera mafiibhi e-single-mode, aya macollimator anoburitsa anoburitsa zvakafara-waist, low-divergence matanda.
Kusiyana kwese kwedanda rakasanganiswa (mumadhigirii) rinogona kufungidzirwanefiber mode field dhayamita (MFD) uye reflector focal kureba (RFL):
Iyo 1/e² dhayamita yedanda rakasanganiswa inosvika:
Semuenzaniso, kushandisa iyo RCR25A-P01 diki collimator kurovedzera iyo P3-630A-FC-1 single-mode fiber, pawavelength ye λ = 633 nm, iyo MFD iri 4.3µm.
Maequation maviri ari pamusoro apa anoratidza kuti divergence angle ndeye 0.01 madhigirii, uye dhayamita yedanda i4.8 mm.
Multimode Fiber Collimation
Iyo yakazara divergence angle yedanda rakasanganiswa inosvika:
Iyo dhayamita ye collimated beam inenge:
Kubuda kwe multimode fiber kazhinji haina kunyatso collimated.
Zvinoenderana neformula iri pamusoro, iyo dhayamita dhayamita inonyanya kukanganiswa neNApanzvimbo iri padyo neOAP reflector, asi sezvo danda richipararira, iyopesvedzero yepakati dhayamita inova yakanyanya kujeka.
Kune iyo yakagadziriswa collimator yataurwa pamusoro, iyo collimated beam diameter ndeyeyakaverengerwa ne2NA*RFL, iyo yakakura kudarika 1/e² dhayamita dhayamita.
Pakusarudza yakagadziriswa collimator, iyo yakatarisa kureba inogona kutorwa kubva kuneinodiwa dhayamita yedanda kuona iyo yakakodzera modhi.
Pane zvipingamupinyi zviviri zvakakosha pakukochekedza multimode fiber.
Chekutanga, akawanda multimode faibha ane rakasiyana chaizvo goho danda rinogona kuvayakavharwa neimba isati yasvika kuOAP reflector, saka iyo fiber NAhaigoni kudarika imwe kukosha; ona tafura yapfuura kuti uwane ruzivo.
Chechipiri, kupatsanurwa kwedanda re collimated kune hukama nepakatidhayamita; sezvo dhayamita yepakati inowedzera, iyo yakakura NA inotsigirwa naiyo collimator inoderera.
Kana iyo collimated danda dhayamita inopfuura yakajeka aperture, kubudadanda richavharwa neimba.
Mamiriro ese ari maviri aya anogona kutungamira mukuderedzwa kwebeam kunaka.
Uye zvakare, OAP maratidziro anogona chete kuwirirana zvakakwana mapoinzi masosi pafocal point.
Iyo yakakura kutsauka kwepoinzi kunobva kubva ku-optical axis, kana iyoyakakura iyo multimode core dhayamita, iyo yakakura kukanganisa kweiyo collimateddanda; kuwedzera kutarisisa kureba kana wavelength kunogona kuderedzakukanganisa.
