Collimator ya Thorlabs ishingiye ku ndorerwamo ya paraboloid ya 90°off-axis (OAP) ifite uburebure buhoraho bw'umuraba ku rugero runini rw'umuraba kandi ni nziza cyane gukoreshwa mu buryo busaba ko habaho uburebure bwinshi bw'umuraba.
Collimator igaragara iboneka mu miterere itatu y'amazu, buri imwe ijyanye na fibre jumpers zifite FC/PC, FC/APC, cyangwa SMA connectors.
Iby'ibanze bya OAP Reflector
OAP (Off-Axis Parabolic) Reflector ni igice cya parabolic yayo nyamukuru.
Kutagira umurongo ugororotse bivuze ko imigozi y'urumuri y'ibice byombi iba ingana ariko ntabwo ihurirana.
Umurongo w'icyerekezo unyura hagati y'icyerekezo n'agace kagaragaza urumuri ka OAP,kandi intera iri hagati y'izi ngingo ebyiri yitwa uburebure bw'ibanze bwagaragajwe(RFL).
Inguni iri hagati y'umurongo ureba kure n'umurongo ureba kure ni Inguni idakora ku murongo,aho ni dogere 90.
Collimator idahinduka
Fibre collimators zihamye zitanga filime ebyiri z'icyuma zigaragaza urumuri rwinshi: -F01 UV-firime ya aluminiyumu yanogejwe hamwe na firime ya feza ya -P01 ifite urwego rwo kurinda, ari byoisabwa kuri collimation ya fiber imwe na multimode naporogaramu zo guhuza fibre nyinshi.
Dukurikije umurambararo w'umuraba wa collimated (kuri fibre ya NA 0.13), zishobora kubabigabanyijemo ibice bine bikurikira:
Amafoto ane ari hejuru ni RC02FC-P01, RC04FC-P01, RC08APC-P01 naRC12SMA-P01 uko bikurikirana.
Bityo rero, dukurikije icyitegererezo cy'ibicuruzwa, dushobora kumenya ibipimo by'ingenziya buri collimator igaragara, harimo n'umurambararo w'umuraba wa collimated, fibreumuhuza n'igitambaro.
Kolimatike za RC02, RC04, na RC08 zirahuye na SM05- imbereimigozi ifatanye, mu gihe collimator ya RC12 ijyanye na SM1- imbereimigozi ifatanye.
Byongeye kandi, collimator ya RC02 ishobora gushyirwa mu gice cya Ø1/2"icyuma gishyiraho kinematic, mu gihe RC02, RC04, na RC08 bishobora gushyirwaho mu buryo butaziguyemu gice cyo gufatiraho Ø1" kinematic (nyuma yo gukuramo impeta y'amaboko ku gice cyo hejuruicyambu cy'ikirere);
Gushyiraho icyuma gifata kinematic byoroshya guhuza imirasire iyo fibre ifatanyebirakenewe.
Collimator Nto
Collimator ntoya igera ku gishushanyo mbonera gito cyane iyo ifite agakoresho ko kugarura urumuri muricyerekezo gitandukanye n'imbere. Ishobora kugabanywamo ibice bibiri hakurikijweuburebure bw'ibanze: RCR25x-P01 na RCR50x-P01, hamwe n'uburebure bw'ibanze bw'ishushoya mm 25.4 na mm 50.8 uko bikurikirana; x iri mu nomero y'icyitegererezo ni fibreubwoko bw'umuhuza, bushobora gusimbuzwa P, A na S kugira ngo bugaragaze FC/PC,Ibihuza bya FC/APC na SMA uko bikurikirana.
Kollimateri nto zishobora gushyirwa mu buryo butaziguye mu byuma bishyiraho lenzi bya Ø1/2", nk'ibyonk'impeta ya SM05RC(/M) n'agakingirizo ka SM05TC.
Niba bikenewe ko habaho gukosora umuvuduko/umuvuduko, bishobora gushyirwa muri kinematic ya Ø1"Shyiramo ukoresheje adaptateri ya SM1A60.
Collimator nto ishobora kandi gushyirwa mu kato ka mm 16sisitemu ikoresha isahani ya SP3 cage cyangwa SC6W cage cube, cyangwa mu 30 mmsisitemu y'akazu ikoresha adaptateri ya SM1A60 n'agace k'akazu ka C4W.
Collimator ihinduka
Collimateur zishobora guhindurwa zishobora guhindura intera iri hagati ya fibre na OAP mirror kugira ngo zirusheho gukora collimation ya buri fibre cyangwa zigahuza urumuri mu mipira imwe cyangwa multimode.
Iyo umurongo wanditswe uhujwe n'ikimenyetso cya ∞, intera iri hagati y'umugoziku gisubizo cya OAP kingana na RFL, kandi collimator itangaumuraba wa collimated (hejuru).
Iyo umurongo wanditswe utandukanye n'ikimenyetso cya ∞, collimator isohora aumurambararo utandukanye cyangwa uhuza, n'intera ntarengwa uvuye ku cyerekezo cyawo uganaHagati mu gasanduku k'inyuma ni -2.2 m na 0.15 m, uko bikurikirana, nk'uko bigaragara murihakurikiraho imibare ibiri.
Iyo igipimo cy’imvange kingana n’ubudashira, indorerwamo za OAP zishobora kugera kuamashusho adafite aho ahuriye n'impinduka.
Nkuko bigaragara ku ishusho iri hepfo, hari kandi na collimateur ebyiri zigarura urumuri zishobora guhindurwabirakwiriye cyane mu guhuza intera ndende, ku buryo umwanya wo hagati w'ubusaumurabyo ushobora kuyoborwa n'ibindi bintu by'urumuri, ibyo bikaba ingirakamaro cyane muporogaramu z'itumanaho zikoreshwa kure.
Collimator ya RCF15x-P01 ishobora gushyirwa mu gikoresho cya SM1RC(/M)impeta cyangwa agakoresho ko gufunga amaboko ka SM1TC ukoresheje igice cy'umukara.
Kugira ngo uhindure umuvuduko/umuvuduko, ni byiza gukoresha Polaris mount, nkaPOLARIS-K2 cyangwa POLARIS-K2VS2L Ø2" kinematic mount ikoresheje AD2Tadaptateri; icyuma gishyiraho POLARIS-K2T SM2 gikoresheje SM2A21adaptateri; cyangwa POLARIS-K15XY 5-axis kinematic mount ikoresheje SM1L03umuyoboro w'ikirahuri na adaptateri ya SM1A68.
Igice cy'aho umuntu atuye cya collimator gihindurwa gifite imigoziimigozi ya SM05 y'imbere n'iy'inyuma ya SM1.
Ingero zo gushyiraho collimatorbigaragazwa mu mashusho abiri akurikira.
Uburyo bumwe bwo guhuza fibre
Iyo ukoresheje insinga zo mu bwoko bumwe, izi collimators zigaragaza urumuri zitanga umusaruro munini-ikibuno, imirasire y'urumuri idahindagurika cyane.
Itandukaniro ryose ry'umuraba wa collimated (muri dogere) rishobora kugereranywahakurikijwe umurambararo w'umuyoboro wa fibre mode (MFD) n'uburebure bwa reflector focal length (RFL):
Umurambararo wa 1/e² w'umuraba wa collimated ni hafi:
Urugero, gukoresha RCR25A-P01 small collimator kugira ngo uhuze P3-Fibre ya 630A-FC-1 ifite uburyo bumwe, ku bunini bw'urukiramende bwa λ = 633 nm, MFD ni 4.3µm.
Ibigereranyo bibiri byavuzwe haruguru bigaragaza ko inguni y'itandukaniro ari dogere 0.01, kandi umurambararo w'umuraba ni mm 4.8.
Uburyo bwinshi bwo guhuza fibre
Inguni yose y'uruhererekane rw'umuraba wa collimated ni hafi:
Ubugari bw'umuraba wa collimated ni hafi:
Umusaruro wa fibre ya multimode ubusanzwe ntuba umeze neza.
Dukurikije formula yavuzwe haruguru, umurambararo w'umuraba ugizweho ingaruka cyane na NAahantu hafi y'agasanduku ka OAP, ariko uko umuraba ugenda ukwirakwira,Ingaruka z'umurambararo w'imbere zirushaho kugaragara.
Ku gikoresho gihamye cyavuzwe haruguru, umurambararo w'umuraba wa collimated niibarwa na 2NA*RFL, irenga umurambararo wa 1/e² w'umurambararo.
Mu guhitamo collimator idahinduka, uburebure bw'ibanze bushobora gusobanurwa uhereye kuriumurambararo w'umuraba ukenewe kugira ngo hamenyekane icyitegererezo gikwiye.
Hari imbogamizi ebyiri z'ingenzi ku bijyanye no guhuza imigozi ya multimode.
Ubwa mbere, insinga nyinshi za multimode zifite urumuri rutandukanye cyane rushobora kubaifunze n'aho iherereye mbere yo kugera kuri reflector ya OAP, bityo fibre NAntibishobora kurenza agaciro runaka; reba imbonerahamwe ibanziriza iyi kugira ngo umenye ibisobanuro birambuye.
Icya kabiri, itandukaniro ry'umuraba wa collimated rifitanye isano n'imbere mu mutimaumurambararo; uko umurambararo w'ibanze wiyongera, NA ntarengwa ishyigikiwe nacollimator iragabanuka.
Iyo umurambararo w'umuraba wa collimated urenze umwobo usobanutse, umusaruro usohokaumuyoboro uzafungwa n'inzu.
Ibi bintu byombi bishobora gutuma ubwiza bw'urumuri bugabanuka.
Byongeye kandi, utugarura-rumuri twa OAP dushobora gusa gupima neza amasoko y'ingingo kuahantu ho kwibanda.
Uko isoko y'ingingo ihinduka cyane uvuye ku murongo w'urumuri, cyangwauko umurambararo w'inkingi ya multimode uba munini, niko ihindagurika rya collimated riba rininiumuraba; kongera uburebure bw'umurambararo cyangwa uburebure bw'umurambararo bishobora kugabanyakugoreka.
