Lub Thorlabs reflective fiber collimator yog ua los ntawm daim iav 90° off-axis paraboloid (OAP) uas muaj qhov ntev focal tas li ntawm ntau qhov wavelength thiab zoo tagnrho rau kev siv hauv cov kab ke uas xav tau collimation ntawm ntau qhov wavelengths.
Lub collimator reflective muaj nyob rau hauv peb lub tsev tsim qauv, txhua tus sib xws nrog cov fiber jumpers nrog FC / PC, FC / APC, lossis SMA connectors.
Cov Ntsiab Lus ntawm OAP Reflector
OAP (Off-Axis Parabolic) Reflector yog ib feem ntawm nws niam txiv parabolic.
Tawm-axis txhais tau hais tias cov axes optical ntawm ob yog sib luag tab sis tsis sib xws.
Lub axis tsom xam hla dhau qhov chaw nruab nrab ntawm qhov tsom xam thiab OAP Reflector,thiab qhov deb ntawm ob lub ntsiab lus no hu ua qhov ntev ntawm qhov cuam tshuam(RFL).
Lub kaum sab xis ntawm qhov axis tsom thiab qhov optical axis yog lub kaum sab xis tawm,uas yog 90 degrees ntawm no.
Collimator ruaj khov
Cov khoom siv fiber collimators ruaj khov muab ob daim hlau uas muaj kev cuam tshuam siab: -F01 UV-zaj duab xis txhuas txhim kho thiab -P01 nyiaj zaj duab xis nrog txheej tiv thaiv, uas yogpom zoo rau ib hom thiab multimode fiber collimation thiabkev siv cov khoom siv fiber ntau multimode.
Raws li lub collimated beam diameter (rau 0.13 NA fiber), lawv tuaj yeem ua taumuab faib ua plaub series hauv qab no:
Plaub daim duab saum toj no yog RC02FC-P01, RC04FC-P01, RC08APC-P01 thiabRC12SMA-P01 feem.
Yog li ntawd, raws li cov qauv khoom, peb tuaj yeem paub cov yam ntxwv tseem ceebntawm txhua lub collimator reflective, suav nrog lub collimated beam diameter, fibertxuas thiab txheej.
Cov RC02, RC04, thiab RC08 collimators sib xws nrog sab hauv SM05-cov xov txuas, thaum lub RC12 collimator sib xws nrog sab hauv SM1-cov xov hlau mounts.
Ntxiv rau, RC02 collimator tuaj yeem ntsia ncaj qha rau hauv Ø1/2"kinematic mount, thaum RC02, RC04, thiab RC08 tuaj yeem ntsia tau ncaj qha rau ntawm qhov kawgrau hauv Ø1 "kinematic mount (tom qab thawj zaug unscrewing lub knurled ring ntawm qhov dawbchaw nres nkoj);
Kev teeb tsa nrog lub kinematic mount ua rau lub beam sib dhos yooj yim thaum txuas fiberyog qhov yuav tsum tau ua.
Collimator me me
Lub collimator me me ua tiav qhov tsim slimmer los ntawm kev muaj lub reflector nyob rau hauvkev taw qhia rov qab mus rau pem hauv ntej. Nws tuaj yeem faib ua ob series raws liqhov ntev ntawm lub teeb: RCR25x-P01 thiab RCR50x-P01, nrog rau qhov ntev ntawm lub teeb rov qab losntawm 25.4 thiab 50.8 hli feem; tus x hauv tus qauv lej yog lub fiberhom txuas, uas tuaj yeem hloov nrog P, A thiab S los sawv cev rau FC / PC,FC/APC thiab SMA connectors feem.
Cov collimators me me tuaj yeem ntsia ncaj qha rau hauv Ø1/2 "lens tube mounts, xws liua lub nplhaib SM05RC (/ M) thiab lub clamp SM05TC.
Yog tias xav tau kev hloov kho suab / yaw, lawv tuaj yeem raug teeb tsa hauv Ø1 "kinematicmount siv SM1A60 adapter.
Lub collimator me me kuj tseem tuaj yeem koom ua ke ncaj qha rau hauv lub tawb 16 hlilub kaw lus siv lub phaj SP3 cage lossis SC6W cage cube, lossis rau hauv 30 mmlub kaw lus tawb siv lub SM1A60 adapter thiab lub C4W cage cube.
Collimator kho tau
Cov collimators kho tau tuaj yeem kho qhov deb ntawm lub fiber mus rau daim iav OAP kom zoo dua qhov collimation ntawm txhua lub fiber lossis txuas lub teeb rau hauv singlemode lossis multimode fibers.
Thaum cov kab sau tau sib phim nrog lub cim ∞, qhov deb ntawm lub fiberrau OAP reflector yog sib npaug rau RFL, thiab lub collimator tso tawm alub teeb sib dhos (saum toj no).
Thaum cov kab sau tseg tsis sib haum nrog lub cim ∞, lub collimator tso tawm ib qhodivergent lossis convergent beam, thiab qhov deb tshaj plaws ntawm nws qhov kev tsom mus rauqhov chaw nruab nrab ntawm lub reflector yog -2.2 m thiab 0.15 m, raws li qhia hauvua raws li ob daim duab.
Thaum qhov sib piv sib txuas sib npaug rau infinity, OAP daim iav tuaj yeem ua tiavkev thaij duab uas txwv tsis pub siv diffraction.
Raws li pom hauv daim duab hauv qab no, ob lub collimators uas hloov kho tau kuj tseem muajzoo heev rau kev sib txuas ntev, yog li ntawd qhov chaw nruab nrab dawblub teeb tuaj yeem tsav nrog lwm cov khoom siv optical, uas yog qhov muaj txiaj ntsig zoo hauvcov ntawv thov kev sib txuas lus ntev.
Lub RCF15x-P01 adjustable collimator tuaj yeem ntsia tau rau hauv SM1RC(/M) sliplub nplhaib lossis SM1TC tes tsho clamp siv seem dub.
Rau kev hloov kho qhov siab/yaw, nws raug pom zoo kom siv Polaris mount, xws lilub POLARIS-K2 lossis POLARIS-K2VS2L Ø2" kinematic mount siv AD2Tadapter; lub POLARIS-K2T SM2-threaded kinematic mount siv lub SM2A21adapter; los yog POLARIS-K15XY 5-axis kinematic mount siv SM1L03lub raj lens thiab SM1A68 adapter.
Qhov kawg ntawm qhov chaw dawb ntawm lub tsev collimator uas kho tau yog xov nrogsab hauv SM05 thiab sab nraud SM1 xov.
Piv txwv ntawm kev teeb tsa lub collimatortau qhia nyob rau hauv ob daim duab hauv qab no.
Ib Hom Fiber Collimation
Thaum collimating ib hom fibers, cov reflective collimators no tsim cov dav- cov kab txaij nyias nyias, cov kab txaij sib txawv.
Tag nrho qhov sib txawv ntawm lub teeb collimated (hauv degrees) tuaj yeem kwv yees taulos ntawm txoj kab uas hla ntawm hom fiber (MFD) thiab qhov ntev ntawm lub reflector (RFL):
Lub 1/e² txoj kab uas hla ntawm ib lub collimated beam yog kwv yees li:
Piv txwv li, siv RCR25A-P01 me me collimator los collimate P3-630A-FC-1 ib hom fiber, ntawm qhov ntev ntawm λ = 633 nm, MFD yog 4.3µm.
Ob qho kev sib npaug saum toj no qhia tau hais tias lub kaum sab xis sib txawv yog 0.01 degreesthiab lub qhov loj ntawm lub raj yog 4.8 mm.
Kev sib txuas ntawm ntau hom fiber ntau
Tag nrho lub kaum sab xis ntawm lub teeb collimated yog kwv yees li:
Lub txoj kab uas hla ntawm lub collimated beam yog kwv yees li:
Cov zis ntawm multimode fiber feem ntau tsis zoo collimated.
Raws li cov mis saum toj no, lub beam diameter feem ntau cuam tshuam los ntawm NAnyob rau ntawm qhov chaw ze rau OAP reflector, tab sis thaum lub teeb nthuav dav, qhovkev cuam tshuam ntawm lub hauv paus txoj kab uas hla ua rau pom tseeb dua.
Rau lub collimator ruaj khov uas tau hais los saum toj no, lub collimated beam diameter yogxam los ntawm 2NA*RFL, uas loj dua 1/e² txoj kab uas hla ntawm lub beam.
Thaum xaiv lub collimator ruaj khov, qhov ntev ntawm lub focal tuaj yeem xav tau los ntawmqhov txoj kab uas hla ntawm lub beam yuav tsum tau txiav txim siab tus qauv tsim nyog.
Muaj ob qho kev txwv tseem ceeb rau kev sib txuas cov fiber ntau multimode.
Ua ntej, feem ntau cov fibers multimode muaj cov zis tawm sib txawv heev uas tuaj yeem ua tauthaiv los ntawm lub tsev ua ntej mus txog OAP reflector, yog li ntawd cov fiber NAtsis pub tshaj ib qho nqi twg; saib lub rooj dhau los kom paub meej ntxiv.
Qhov thib ob, qhov sib txawv ntawm lub teeb collimated muaj feem cuam tshuam nrog lub hauv paustxoj kab uas hla; raws li txoj kab uas hla ntawm lub hauv paus nce ntxiv, qhov siab tshaj plaws NA txhawb nqa los ntawmlub collimator txo qis.
Yog tias lub collimated beam diameter tshaj qhov aperture ntshiab, qhov tso zislub beam yuav raug thaiv los ntawm lub tsev.
Ob qho xwm txheej no tuaj yeem ua rau qhov zoo ntawm lub teeb tsis zoo.
Ntxiv rau, OAP reflectors tsuas yog tuaj yeem sib sau ua ke cov ntsiab lus ntawm qhov chawqhov chaw tseem ceeb.
Qhov loj dua qhov kev hloov pauv ntawm qhov chaw taw qhia los ntawm qhov optical axis, lossis qhovqhov loj dua ntawm multimode core diameter, qhov loj dua qhov kev cuam tshuam ntawm collimatedbeam; kev nce qhov ntev ntawm qhov kev cuam tshuam lossis qhov wavelength tuaj yeem txo qhovkev cuam tshuam.
