Chojambulira cha Thorlabs chowunikira bwino chimapangidwa pa galasi la 90°off-axis paraboloid (OAP) lomwe lili ndi kutalika kokhazikika pamlingo waukulu wa wavelength ndipo ndi labwino kwambiri kugwiritsidwa ntchito m'makina omwe amafuna ma wavelength angapo.
Collimator yowunikira imapezeka m'mapangidwe atatu a nyumba, iliyonse imagwirizana ndi ma fiber jumpers okhala ndi zolumikizira za FC/PC, FC/APC, kapena SMA.
Zoyambira za OAP Reflector
Chowunikira cha OAP (Off-Axis Parabolic) ndi gawo la chowunikira chake chachikulu.
Kupatula mzere kumatanthauza kuti ma axes optical a awiriwa ndi ofanana koma si ogwirizana.
Mzere wolunjika umadutsa pakati pa chowunikiracho ndi OAP Reflector,ndipo mtunda pakati pa mfundo ziwirizi umatchedwa kutalika kowonekera(RFL).
Ngodya pakati pa mzere wolunjika ndi mzere wowala ndi ngodya yosakhala yolunjika,komwe kuli madigiri 90 pano.
Collimator Yokhazikika
Ma collimator okhazikika amapereka mafilimu awiri achitsulo owunikira kwambiri: -F01 UV-filimu ya aluminiyamu yowonjezeredwa ndi filimu yasiliva ya -P01 yokhala ndi gawo loteteza, zomwe ndiakulimbikitsidwa kugwiritsa ntchito single-mode ndi multimode fiber collimation ndintchito zolumikizira ulusi wa multimode.
Malinga ndi kukula kwa m'mimba mwake wa collimated beam (ya ulusi wa 0.13 NA), akhoza kukhalayagawidwa m'magulu anayi otsatirawa:
Zithunzi zinayi zomwe zili pamwambapa ndi RC02FC-P01, RC04FC-P01, RC08APC-P01 ndiRC12SMA-P01 motsatana.
Chifukwa chake, malinga ndi chitsanzo cha malonda, titha kudziwa magawo akuluakuluya collimator iliyonse yowunikira, kuphatikiza m'mimba mwake wa collimated beam, ulusicholumikizira ndi chophimba.
Ma collimator a RC02, RC04, ndi RC08 amagwirizana ndi SM05- mkatizomangira zokhala ndi ulusi, pomwe RC12 collimator imagwirizana ndi SM1- mkatizomangira zokhala ndi ulusi.
Kuphatikiza apo, collimator ya RC02 ikhoza kuyikidwa mwachindunji mu Ø1/2"choyimitsa cha kinematic, pomwe RC02, RC04, ndi RC08 zitha kuyikidwa mwachindunjimu choyimitsa cha Ø1" kinematic (mutatsegula mphete yopindika koyamba pa freedoko lamlengalenga);
Kuyika ndi choyimitsa cha kinematic kumathandiza kuti kuwala kugwirizane bwino pamene ulusi ulumikizanachofunika.
Collimator Yaing'ono
Collimator yaying'ono imapeza kapangidwe kowonda kwambiri chifukwa chokhala ndi chowunikira mkatimbali yosiyana ndi kutsogolo. Ikhoza kugawidwa m'magulu awiri malinga ndikutalika kwa focal: RCR25x-P01 ndi RCR50x-P01, ndi kutalika kwa focal kowunikiraya 25.4 ndi 50.8 mm motsatana; x mu nambala ya chitsanzo ndi ulusimtundu wa cholumikizira, chomwe chingasinthidwe ndi P, A ndi S kuti chiyimire FC/PC,Zolumikizira za FC/APC ndi SMA motsatana.
Ma collimator ang'onoang'ono amatha kuyikidwa mwachindunji mu zomangira za chubu cha lenzi cha Ø1/2", mongamonga mphete yolowera ya SM05RC(/M) ndi chomangira cha SM05TC.
Ngati pakufunika kusintha pitch/yaw, zitha kuyikidwa mu kinematic ya Ø1"Ikani pogwiritsa ntchito adaputala ya SM1A60.
Collimator yaying'ono imathanso kulowetsedwa mwachindunji mu khola la 16 mmmakina pogwiritsa ntchito mbale ya khola la SP3 kapena chigawo cha khola la SC6W, kapena mu 30 mmmakina osungira zitseko pogwiritsa ntchito adaputala ya SM1A60 ndi kyubu ya zitseko ya C4W.
Collimator Yosinthika
Ma collimator osinthika amatha kusintha mtunda kuchokera ku ulusi kupita ku galasi la OAP kuti akonze bwino collimation ya ulusi uliwonse kapena kuphatikiza kuwala kukhala singlemode kapena multimode fibers.
Pamene mzere wolembedwawo ukugwirizana ndi chizindikiro cha ∞, mtunda wochokera ku ulusiku OAP reflector ndi yofanana ndi RFL, ndipo collimator imatulutsa amtanda wozungulira (pamwambapa).
Pamene mzere wolembedwa wapatuka ku chizindikiro cha ∞, collimator imatulutsa amtanda wosiyana kapena wolumikizana, ndi mtunda wapamwamba kwambiri kuchokera pa cholinga chake kupita kuPakati pa chowunikira ndi -2.2 m ndi 0.15 m, motsatana, monga momwe zasonyezedwera mukutsatira ziwerengero ziwiri.
Ngati chiŵerengero cha conjugate chili chofanana ndi chosatha, magalasi a OAP amatha kukwaniritsakujambula zithunzi zochepa zosokoneza.
Monga momwe chithunzi chili pansipa chikusonyezera, ma collimator awiri osinthika owunikira nawonso aliyoyenera kwambiri polumikizira mtunda wautali, kotero kuti malo omasuka apakatimtanda ukhoza kuyendetsedwa ndi zinthu zina zowunikira, zomwe zimathandiza kwambirimapulogalamu olumikizirana patali.
Collimator yosinthika ya RCF15x-P01 ikhoza kuyikidwa mu slip ya SM1RC(/M)mphete kapena chomangira cha SM1TC pogwiritsa ntchito gawo lakuda.
Pofuna kusintha pitch/yaw, ndi bwino kugwiritsa ntchito Polaris mount, mongachoyimitsa cha POLARIS-K2 kapena POLARIS-K2VS2L Ø2" pogwiritsa ntchito AD2Tadaputala; choyimitsa cha POLARIS-K2T SM2 cholumikizidwa pogwiritsa ntchito SM2A21adaputala; kapena choyimitsa cha POLARIS-K15XY cha 5-axis kinematic pogwiritsa ntchito SM1L03chubu cha lenzi ndi adaputala ya SM1A68.
Malekezero a malo omasuka a nyumba yosinthika ya collimator ali ndi ulusiulusi wamkati wa SM05 ndi wakunja wa SM1.
Zitsanzo za kukhazikitsa collimatorzikuwonetsedwa m'zithunzi ziwiri zotsatirazi.
Kuphatikizika kwa Ulusi wa Njira Imodzi
Popanga ulusi wa single-mode, ma collimator owunikira awa amapanga zambiri-chiuno, mipiringidzo yocheperako.
Kusiyana konse kwa mtanda wa collimated (mu madigiri) kungayerekezedwendi m'mimba mwake wa munda wa fiber mode (MFD) ndi kutalika kwa reflector focal (RFL):
M'mimba mwake wa 1/e² wa mtanda wa collimated ndi pafupifupi:
Mwachitsanzo, kugwiritsa ntchito RCR25A-P01 small collimator kuti mukonze P3-Ulusi wa 630A-FC-1 single-mode, womwe uli ndi mafunde a λ = 633 nm, MFD ndi 4.3µm.
Ma equation awiri omwe ali pamwambapa akuwonetsa kuti ngodya ya divergence ndi madigiri 0.01, ndipo m'mimba mwake wa mtanda ndi 4.8 mm.
Kuphatikizika kwa Ulusi wa Multimode
Ngodya yonse yosiyana ya mtanda wa collimated ndi pafupifupi:
M'mimba mwake wa mtanda wa collimated ndi pafupifupi:
Mphamvu ya ulusi wa multimode nthawi zambiri siili bwino.
Malinga ndi njira yomwe ili pamwambapa, kukula kwa mtanda kumakhudzidwa kwambiri ndi NApamalo pafupi ndi chowunikira cha OAP, koma pamene kuwalako kukufalikira,Mphamvu ya m'mimba mwake wa pakati imawonekera kwambiri.
Pa collimator yokhazikika yomwe yatchulidwa pamwambapa, m'mimba mwake wa collimated beam ndiKuwerengedwa ndi 2NA*RFL, yomwe ndi yayikulu kuposa 1/e² beam diameter.
Posankha collimator yokhazikika, kutalika kwa focal kumatha kuganiziridwa kuchokera kum'mimba mwake wa mtanda wofunikira kuti mudziwe chitsanzo choyenera.
Pali zoletsa ziwiri zofunika pa collimating multimode fibers.
Choyamba, ulusi wambiri wa multimode uli ndi kuwala kotulutsa kosiyana kwambiri komwe kungakhalechotsekedwa ndi nyumbayo isanafike pa chowunikira cha OAP, kotero ulusi NAsizingapitirire mtengo winawake; onani tebulo lapitalo kuti mudziwe zambiri.
Chachiwiri, kusiyana kwa mtanda wa collimated kumakhudzana ndi pakatim'mimba mwake; pamene m'mimba mwake wa pakati ukuwonjezeka, NA yayikulu yomwe imathandizidwa ndicollimator imachepa.
Ngati m'mimba mwake wa collimated beam upitirira mpata woonekera bwino, zotsatira zakemtanda udzatsekedwa ndi nyumbayo.
Zonsezi zingayambitse kuchepa kwa kuwala kwa dzuwa.
Kuphatikiza apo, ma reflector a OAP amatha kufananiza bwino magwero a mfundo pamfundo yofunika kwambiri.
Kupatuka kwakukulu kwa gwero la mfundo kuchokera ku mzere wowala, kapenaKukula kwa mainchesi a multimode core, kusokonekera kwa collimated kumakulirakulirakuwala; kuwonjezera kutalika kwa kuwala kapena kutalika kwa mafunde kungachepetse kuwalalakwitsidwa.
