The Thorlabs reflective fiber collimator imachokera pa galasi la 90 ° off-axis paraboloid (OAP) lomwe limakhala ndi utali wokhazikika pamtunda waukulu wa wavelength ndipo ndiloyenera kugwiritsidwa ntchito pamakina omwe amafunikira kugunda kwa mafunde angapo.
Mwala wonyezimira umapezeka m'mapangidwe atatu a nyumba, iliyonse yogwirizana ndi ma fiber jumpers okhala ndi FC/PC, FC/APC, kapena SMA zolumikizira.
Zoyambira za OAP Reflector
OAP (Off-Axis Parabolic) Reflector ndi gawo la makolo ake.
Off-axis amatanthauza kuti nkhwangwa za kuwala za ziwirizi ndizofanana koma sizinangochitika mwangozi.
Mzere wolunjika umadutsa pakati pa cholinga ndi OAP Reflector,ndipo mtunda pakati pa mfundo ziwirizi umatchedwa utali wowonekera(RFL).
Mphepete mwa ngodya yomwe ili pakati pa nsonga yolunjika ndi nsonga ya kuwala ndi mbali ya off-axis,komwe kuli madigiri 90 apa.
Collimator Yokhazikika
Fixed fiber collimators imapereka mafilimu awiri achitsulo owoneka bwino kwambiri: -F01 UV-filimu yowonjezereka ya aluminiyumu ndi -P01 filimu yasiliva yokhala ndi wosanjikiza zoteteza, zomwe ziliakulimbikitsidwa kuti agwirizane ndi single-mode ndi multimode fiber collimation ndiMultimode fiber coupling application.
Malinga ndi collimated mtengo awiri (kwa 0,13 NA CHIKWANGWANI), iwo akhoza kukhalaadagawidwa m'magulu anayi otsatirawa:
Zithunzi zinayi pamwambapa ndi RC02FC-P01, RC04FC-P01, RC08APC-P01 ndiMbiri ya RC12SMA-P01
Choncho, malinga ndi chitsanzo cha mankhwala, tikhoza kudziwa magawo akuluakuluwa collimator iliyonse yowunikira, kuphatikiza mitayo ya mtengo, ulusicholumikizira ndi zokutira.
Ma collimators a RC02, RC04, ndi RC08 amagwirizana ndi mkati mwa SM05-zokwera ulusi, pamene RC12 collimator n'zogwirizana ndi mkati SM1-zokwera ulusi.
Kuphatikiza apo, RC02 collimator imatha kukhazikitsidwa mwachindunji mu Ø1/2"kinematic mount, pomwe RC02, RC04, ndi RC08 zitha kukhazikitsidwa mwachindunjimu Ø1 "kinematic phiri (mutatha kumasula mphete yokhotakhota pauleredoko lamlengalenga);
Kukwera ndi phiri la kinematic kumathandizira kulumikizana kwa mtengo pamene ulusi umagwirizanachofunika.
Small Collimator
The collimator yaying'ono imakwaniritsa kapangidwe kake kocheperako pokhala ndi chowonetsera mumoyang'anizana ndi kutsogolo. Ikhoza kugawidwa m'magulu awiri malinga ndikutalika kwapakati: RCR25x-P01 ndi RCR50x-P01, yokhala ndi utali wowoneka bwino25.4 ndi 50.8 mm motsatira; x mu nambala yachitsanzo ndi ulusimtundu wolumikizira, womwe ungalowe m'malo ndi P, A ndi S kuyimira FC/PC,FC/APC ndi SMA zolumikizira motsatana.
Ma collimator ang'onoang'ono amatha kuyikidwa mwachindunji mu Ø1/2" machubu a lens, mongamonga mphete ya SM05RC(/M) ndi SM05TC clamp.
Ngati kusintha kwa phula/yaw kumafunika, kumatha kuyikidwa mu Ø1 "kinematicphiri pogwiritsa ntchito adapter ya SM1A60.
Collimator yaying'ono imathanso kuphatikizidwa mwachindunji mu khola la 16 mmdongosolo pogwiritsa ntchito mbale SP3 khola kapena SC6W khola kyubu, kapena mu 30 mmmakina ogwiritsira ntchito SM1A60 adapter ndi C4W khola kyubu.
Collimator yosinthika
Ma collimators osinthika amatha kusintha mtunda kuchokera ku fiber kupita pa kalilole wa OAP kuti akwaniritse kulumikizidwa kwa ulusi uliwonse kapena kuyatsa kuwala kukhala singlemode kapena ulusi wa multimode.
Pamene mzere wolembedwa ukugwirizana ndi chizindikiro cha ∞, mtunda kuchokera ku ulusiku chiwonetsero cha OAP ndi chofanana ndi RFL, ndipo zotsatira za collimator amtengo wopindika (pamwambapa).
Pamene mzere wolembedwa upatuka pa chizindikiro cha ∞, collimator imatulutsa amtengo wosiyana kapena wopindika, ndi mtunda wautali kwambiri kuchokera pamalingaliro ake mpakaPakati pa chowunikira ndi -2.2 m ndi 0.15 m, motero, monga momwe tawonetsera mukutsatira ziwerengero ziwiri.
Pamene chiŵerengero cha conjugate chili chofanana ndi chosawerengeka, magalasi a OAP akhoza kukwaniritsadiffraction-limited kujambula.
Monga momwe tawonetsera pachithunzichi, ma collimator awiri osinthika osinthika nawonso aliabwino kwambiri kugwirizana mtunda wautali, kotero kuti wapakatikati ufulu-dangamtengowo ukhoza kuwongoleredwa ndi zinthu zina zowoneka bwino, zomwe ndizothandiza kwambirintchito zoyankhulirana mtunda wautali.
Chokolezera chosinthika cha RCF15x-P01 chikhoza kuyikidwa pa slip SM1RC(/M)mphete kapena chingwe chamanja cha SM1TC pogwiritsa ntchito gawo lakuda.
Pakusintha phula / yaw, tikulimbikitsidwa kugwiritsa ntchito phiri la Polaris, mongaphiri la POLARIS-K2 kapena POLARIS-K2VS2L Ø2" pogwiritsa ntchito AD2Tadaputala; phiri la POLARIS-K2T SM2 lopangidwa ndi kinematic pogwiritsa ntchito SM2A21adaputala; kapena POLARIS-K15XY 5-axis kinematic phiri pogwiritsa ntchito SM1L03lens chubu ndi SM1A68 adaputala.
Mapeto a malo aulere a nyumba yosinthika ya collimator amalumikizidwa ndimkati SM05 ndi kunja SM1 ulusi.
Zitsanzo za kuyika collimatorzikuwonetsedwa muzithunzi ziwiri zotsatirazi.
Single Mode Fiber Collimation
Mukaphatikiza ulusi wamtundu umodzi, ma collimators owoneka bwinowa amatulutsa zambiri- m'chiuno, matabwa otsika-siyana.
Kusiyana kwathunthu kwa mtengo wopindika (mu madigiri) kutha kuyerekezedwandi fiber mode field diameter (MFD) ndi reflector focal length (RFL):
Kutalika kwa 1/e² kwa mtengo wosakanikirana ndi pafupifupi:
Mwachitsanzo, kugwiritsa ntchito RCR25A-P01 collimator yaying'ono kuti igwirizane ndi P3-630A-FC-1 single-mode fiber, pamtunda wa λ = 633 nm, MFD ndi 4.3µm.
Ma equation awiri omwe ali pamwambapa akuwonetsa kuti divergence angle ndi madigiri 0.01, ndipo m'mimba mwake ndi 4.8 mm.
Multimode Fiber Collimation
Kusiyanitsa kokwanira kwa mtengo wosakanikirana ndi pafupifupi:
The diameter of the collimated mtengo ndi pafupifupi:
Kutulutsa kwa multimode fiber nthawi zambiri sikuphatikizana bwino.
Malinga ndi formula yomwe ili pamwambapa, kutalika kwa mtengo kumakhudzidwa makamaka ndi NApamalo pafupi ndi chiwonetsero cha OAP, koma ngati mtengowo ukufalikira, ndiChikoka chapakati pakati chimawonekera kwambiri.
Kwa collimator yokhazikika yomwe yatchulidwa pamwambapa, kutalika kwa mtengo wa collimated ndiyowerengeredwa ndi 2NA*RFL, yomwe ndi yayikulu kuposa 1/e² m'mimba mwake.
Posankha collimator yokhazikika, kutalika kwapakati kumatha kuwerengedwa kuchokera kuzimafunikira m'mimba mwake kuti mudziwe mtundu woyenera.
Pali zolepheretsa ziwiri zofunika pakuphatikiza ulusi wa multimode.
Choyamba, ulusi wambiri wa multimode uli ndi mtengo wosiyana kwambiri womwe ungakhaleotsekedwa ndi nyumbayo asanafike chowunikira cha OAP, kotero CHIKWANGWANI NAsangathe kupitirira mtengo wina; onani tebulo lapitalo kuti mudziwe zambiri.
Chachiwiri, kusiyana kwa mtengo wa collimated kumagwirizana ndi pachimakem'mimba mwake; pamene mainchesi akuwonjezeka, kuchuluka kwa NA komwe kumathandizidwa ndicollimator imachepa.
Ngati collimated mtengo awiri kuposa bwino pobowo, linanena bungwemtengo udzatsekedwa ndi nyumba.
Zonse ziwirizi zitha kupangitsa kuti mtengo ukhale wotsika.
Kuphatikiza apo, zowunikira za OAP zimatha kungolumikizana bwino ndi magwero a mfundo papoyambira.
Kupatuka kwakukulu kwa gwero la mfundo kuchokera ku optical axis, kapena thekukula kwa multimode core diameter, kumapangitsanso kupotoza kwa collimatedmtengo; kuonjezera chiwonetsero cha kutalika kwa kutalika kapena kutalika kwa mafunde kumatha kuchepetsalakwitsidwa.
