Thorlabs yerekana fibre collimator ishingiye kuri 90 ° off-axis paraboloid (OAP) indorerwamo ifite uburebure buri gihe hejuru yumurambararo mugari kandi nibyiza gukoreshwa muri sisitemu isaba guhuriza hamwe uburebure bwinshi.
Collimator yerekana iraboneka mubishushanyo bitatu byamazu, buri kimwe kijyanye na fibre isimbuka hamwe na FC / PC, FC / APC, cyangwa SMA ihuza.
Ibyibanze bya OAP
OAP (Off-Axis Parabolike) Reflector ni igice cyababyeyi parabolike.
Off-axis bivuze ko optique ya axe ya byombi iringaniye ariko ntabwo ihuye.
Icyerekezo cyibanze kinyura hagati yibanze hamwe na OAP Reflector,kandi intera iri hagati yizi ngingo zombi yitwa uburebure bwerekanwe(RFL).
Inguni hagati yibanda kumurongo hamwe na optique ya axis ni off-axis Inguni,ni dogere 90 hano.
Gukusanya neza
Fibre colibator ihamye itanga ibyuma bibiri byerekana ibyuma byerekana: -F01 UV-yazamuye firime ya aluminium na -P01 ya firime ya silver hamwe na layer yo kurinda, aribyobirasabwa kubwuburyo bumwe na multimode fibre hamwe naMultimode fibre ihuza porogaramu.
Ukurikije diameter yegeranijwe (kuri fibre 0.13 NA), irashoboraigabanijwemo ibice bine bikurikira:
Amashusho ane hejuru ni RC02FC-P01, RC04FC-P01, RC08APC-P01 naRC12SMA-P01.
Kubwibyo, dukurikije icyitegererezo cyibicuruzwa, dushobora kumenya ibipimo nyamukuruya buri cyegeranyo cyerekana, harimo diametre yegeranye, fibreumuhuza.
Imashini za RC02, RC04, na RC08 zirahuza imbere muri SM05-urudodo rudodo, mugihe RC12 collimator ihuza imbere na SM1-Urudodo.
Byongeye kandi, imashini ya RC02 irashobora gushyirwaho amaherezo muri Ø1 / 2 "umusozi wa kinematike, mugihe RC02, RC04, na RC08 bishobora gushyirwaho amaherezomumusozi Ø1 "umusozi wa kinematike (nyuma yo kubanza gukuramo impeta yamenetse kubusaicyambu);
Kwishyiriraho umusozi wa kinematike byorohereza guhuza imirongo iyo fibre ihuzani ngombwa.
Ntoya
Gitoya ya collimator igera ku gishushanyo cyoroheje mugira icyerekezo muriIcyerekezo gitandukanye imbere. Irashobora kugabanywamo ibice bibiri ukurikijeuburebure bwibanze: RCR25x-P01 na RCR50x-P01, hamwe n'uburebure bwibanzeya 25.4 na 50.8 mm; x muri nimero yicyitegererezo ni fibreubwoko bwihuza, bushobora gusimburwa na P, A na S kugirango uhagararire FC / PC,FC / APC na SMA ihuza.
Imashini ntoya irashobora gushirwa muburyo butaziguye muri Ø1 / 2 "lens tube mitingi, nkiyink'impeta ya SM05RC (/ M) na clamp ya SM05TC.
Niba ikibanza / yaw gikenewe guhinduka, birashobora gushirwa muri Ø1 "kinematikegushiraho ukoresheje adaptate ya SM1A60.
Gitoya ya collimator irashobora kandi kwinjizwa mu kato ka mm 16sisitemu ukoresheje isahani ya SP3 cyangwa c6 cage cube, cyangwa muri mm 30sisitemu ya cage ukoresheje adaptate ya SM1A60 na c4W cage cube.
Guhinduranya
Guhinduranya collimator birashobora guhindura intera kuva fibre kugeza kuri mirror ya OAP kugirango hongerwe hamwe guhuza buri fibre cyangwa guhuza urumuri muri fibre imwe cyangwa multimode.
Iyo umurongo wanditse uhujwe na ∞ ikimenyetso, intera ya fibrekuri OAP yerekana ibintu bingana na RFL, hamwe na collimator isohoka aibiti byegeranye (hejuru).
Iyo umurongo wanditse utandukiriye kuva ∞ ikimenyetso, inkoranyamagambo isohoka agutandukana cyangwa guhuza urumuri, nintera ntarengwa kuva yibanze kuriHagati yumucyo ni -2.2 m na 0,15 m, nkuko bigaragara murigukurikira imibare ibiri.
Iyo igipimo cya conjugate kingana nubuziraherezo, indorerwamo za OAP zirashobora kugerahoamashusho atandukanijwe.
Nkuko bigaragara ku gishushanyo gikurikira, ibice bibiri bishobora guhinduka byerekana kandibikwiranye cyane no guhuza intera ndende, kuburyo hagati yubusa-umwanyaurumuri rushobora kuyoborwa nibindi bikoresho bya optique, bifite akamaro kanini muriintera ndende itumanaho.
RCF15x-P01 ishobora guhindurwa irashobora gushirwa mumurongo wa SM1RC (/ M)impeta cyangwa SM1TC clamp clamp ukoresheje igice cyirabura.
Kubijyanye na pitch / yaw, birasabwa gukoresha umusozi wa Polaris, nkaPOLARIS-K2 cyangwa POLARIS-K2VS2L Ø2 "umusozi wa kinematike ukoresheje AD2Tadapt; POLARIS-K2T SM2-ifite insanganyamatsiko ya kinematike ikoresheje SM2A21adapt; cyangwa POLARIS-K15XY 5-axis ya kinematike umusozi ukoresheje SM1L03lens tube na adapt ya SM1A68.
Umwanya-wubusa impera yimyubakire ya collimator ihujwe hamweimbere SM05 ninyuma ya SM1 yo hanze.

Uburyo bumwe bwo guhuza fibre
Mugihe cyo gukusanya fibre imwe-fibre, ibyo byegeranya bitanga umusaruro mugari-ibiti, ibiti bito-bitandukanya.
Itandukaniro rusange ryibiti byegeranijwe (muri dogere) birashobora kugereranywana fibre yuburyo bwa fibre yumurima diameter (MFD) hamwe nuburebure bwerekana (RFL):
Diameter ya 1 / e² yumurambararo wegeranye ni hafi:
Kurugero, ukoresheje RCR25A-P01 collimator ntoya kugirango uhuze P3-630A-FC-1 fibre yuburyo bumwe, ku burebure bwa λ = 633 nm, MFD ni 4.3µm.
Ibigereranyo bibiri byavuzwe haruguru byerekana ko impande zinyuranye ari dogere 0.01, na diameter ya beam ni 4,8 mm.
Multimode Fibre Gukusanya
Ingero zose zo gutandukanya urumuri rwegeranijwe ni hafi:
Diameter yikibiti cyegeranijwe ni hafi:
Ibisohoka bya fibre fibre mubisanzwe ntabwo byegeranye neza.
Ukurikije formulaire yavuzwe haruguru, diameter ya beam yibasiwe cyane na NAkumwanya uri hafi ya OAP yerekana, ariko nkuko urumuri rukwirakwiza ,.Ingaruka ya diameter yibanze igenda irushaho kugaragara.
Kuri collimator ihamye yavuzwe haruguru, diameter yegeranye nikubarwa na 2NA * RFL, irenze 1 / e² diameter.
Mugihe uhisemo collimator ihamye, uburebure bwibanze bushobora gutangwa kuva kuribisabwa diameter kugirango umenye icyitegererezo gikwiye.
Hariho ibintu bibiri byingenzi bigabanya gukusanya fibre nyinshi.
Ubwa mbere, fibre nyinshi ya fibre ifite ibyasohotse bitandukanye cyane bishobora kubayahagaritswe namazu mbere yo kugera kuri OAP yerekana, fibre NAntishobora kurenga agaciro runaka; reba imbonerahamwe ibanza kugirango ubone ibisobanuro.
Icya kabiri, itandukaniro ryibiti byegeranijwe bifitanye isano nintangirirodiameter; nkuko diameter yibanze yiyongera, ntarengwa NA ishyigikiwe nainkoranyamagambo iragabanuka.
Niba diameter yegeranijwe irenze aperture isobanutse, ibisohokaibiti bizahagarikwa n'inzu.
Ibi bihe byombi birashobora gutuma ubwiza bwibiti bugabanuka.
Mubyongeyeho, ibyuma bya OAP birashobora gusa guhuza neza ingingo zituruka kuriIngingo yibanze.
Kurenza gutandukana kwingingo yatanzwe kuva optique, cyangwa inini ya diameter ya multimode nini, niko kugoreka kwegeranijweurumuri; kongera ibitekerezo byerekanwe uburebure cyangwa uburebure bwumurongo birashobora kugabanyakugoreka.
