Thorlabs reflective fiber collimator yog raws li 90 ° tawm-axis paraboloid (OAP) daim iav nrog qhov ntev focal ntev dhau ntawm qhov dav wavelength ntau yam thiab zoo tagnrho rau siv hauv cov tshuab uas xav tau kev sib tsoo ntawm ntau lub wavelengths.
Lub reflective collimator muaj nyob rau hauv peb lub tsev tsim, txhua qhov sib xws nrog fiber ntau jumpers nrog FC / PC, FC / APC, los yog SMA connectors.
Lub hauv paus ntawm OAP Reflector
OAP (Off-Axis Parabolic) Reflector yog ib feem ntawm nws niam txiv parabolic.
Off-axis txhais tau hais tias qhov kho qhov muag axes ntawm ob yog tib yam tab sis tsis coincident.
Lub hom phiaj axis dhau los ntawm qhov nruab nrab ntawm qhov tsom thiab OAP Reflector,thiab qhov kev ncua deb ntawm ob lub ntsiab lus no yog hu ua qhov cuam tshuam focal ntev(RFL).
Lub kaum sab xis ntawm lub focusing axis thiab optical axis yog lub kaum sab xis off-axis,uas yog 90 degrees ntawm no.
Tsau Collimator
Tsau fiber ntau collimators muab ob lub siab reflectivity hlau zaj duab xis: -F01 UV-txhim kho aluminium zaj duab xis thiab -P01 nyiaj zaj duab xis nrog txheej tiv thaiv, uas yogpom zoo rau ib hom thiab multimode fiber ntau collimation thiabmultimode fiber ntau coupling daim ntaub ntawv.
Raws li lub collimated beam txoj kab uas hla (rau 0.13 NA fiber), lawv tuaj yeem ua taumuab faib ua plaub series nram qab no:
Plaub daim duab saum toj no yog RC02FC-P01, RC04FC-P01, RC08APC-P01 thiabRC12SMA-P01 raws.
Yog li ntawd, raws li cov qauv khoom, peb tuaj yeem paub qhov tseem ceeb ntawm cov khoomntawm txhua qhov sib cuam tshuam collimator, suav nrog collimated beam txoj kab uas hla, fiber ntauconnector thiab txheej.
Lub RC02, RC04, thiab RC08 collimators yog sib xws nrog sab hauv SM05-threaded mounts, thaum lub RC12 collimator yog sib xws nrog SM1-threaded mounts.
Tsis tas li ntawd, RC02 collimator tuaj yeem txuas ncaj qha rau hauv Ø1/2 "kinematic mount, thaum lub RC02, RC04, thiab RC08 tuaj yeem xaus-mounted ncaj qharau hauv Ø1 "kinematic mount (tom qab thawj zaug unscrewing lub nplhaib knurled ntawm dawbchaw nres nkoj);
Mounting nrog lub kinematic mount pab txhawb nqa beam kev sib raug zoo thaum fiber ntau couplingyog yuav tsum tau.
Me Collimator
Lub collimator me me ua tiav ib qho qauv tsim los ntawm kev muaj lub reflector hauvopposite direction mus rau pem hauv ntej. Nws tuaj yeem muab faib ua ob ntu raws liLub focal ntev: RCR25x-P01 thiab RCR50x-P01, nrog rau qhov focal ntev25.4 thiab 50.8 mm feem; tus x hauv tus qauv naj npawb yog fiber ntauconnector hom, 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 txuas ncaj qha rau hauv Ø1/2 "lens tube mounts, xws liRaws li SM05RC (/M) ntiv nplhaib ntiv nplhaib thiab SM05TC clamp.
Yog hais tias yuav tsum tau hloov pitch / yaw, lawv tuaj yeem ntsia tau rau hauv Ø1 "kinematicmount siv SM1A60 adapter.
Lub collimator me me kuj tuaj yeem ua ke ncaj qha rau hauv lub tawb 16 hlisiv lub SP3 tawb phaj los yog SC6W tawb lub voos xwmfab, los yog mus rau hauv ib tug 30 hlitawb system siv SM1A60 adapter thiab C4W tawb lub voos xwmfab.
Adjustable Collimator
Adjustable collimators tuaj yeem kho qhov kev ncua deb ntawm fiber ntau rau OAP daim iav kom ua kom zoo dua qhov sib tsoo ntawm txhua qhov fiber ntau los yog ob peb lub teeb rau hauv singlemode lossis multimode fibers.
Thaum cov kab ntawv sau ua ke nrog lub cim ∞, qhov kev ncua deb ntawm cov fiber ntaurau OAP reflector yog sib npaug rau RFL, thiab cov collimator outputs acollimated beam (saum toj no).
Thaum cov kab ntawv sau tau sib txawv ntawm lub cim ∞, tus collimator outputs adivergent los yog convergent beam, thiab qhov siab tshaj plaws deb ntawm nws tsom mus rauQhov nruab nrab ntawm lub reflector yog -2.2 m thiab 0.15 m, raws li qhia hauvua raws li ob daim duab.
Thaum lub conjugate piv yog sib npaug rau infinity, OAP iav tuaj yeem ua tiavdiffraction-limited duab.
Raws li pom nyob rau hauv daim duab hauv qab no, ob adjustable reflective collimators kujheev haum rau kev sib txuas ntev, kom qhov nruab nrab qhov chaw dawbbeam tuaj yeem coj nrog lwm cov khoom siv kho qhov muag, uas yog qhov tseem ceeb heev hauvdaim ntawv thov kev sib txuas lus mus ntev.
Lub RCF15x-P01 adjustable collimator tau mounted nyob rau hauv ib tug SM1RC (/M) swblub nplhaib lossis SM1TC lub tes tsho clamp siv cov ntu dub.
Rau pitch / yaw hloov, nws raug nquahu kom siv Polaris mount, xws liPOLARIS-K2 lossis POLARIS-K2VS2L Ø2 "kinematic mount siv AD2Tadapter; POLARIS-K2T SM2-xov kinematic mount siv SM2A21adapter; los yog POLARIS-K15XY 5-axis kinematic mount siv SM1L03Lens tube thiab SM1A68 adapter.
Qhov chaw dawb-qhov kawg ntawm lub tsev kho kom haum collimator yog threaded nrogInternal SM05 thiab lwm SM1 threads.
Piv txwv ntawm mounting lub collimatormuaj nyob rau hauv ob daim duab hauv qab no.
Tib hom Fiber Collimation
Thaum collimating ib hom fibers, cov reflective collimators tsim dav- lub duav, qis-divergence kab teeb.
Tag nrho divergence ntawm ib tug collimated beam (hauv degrees) yuav kwv yeeslos ntawm fiber ntau hom teb txoj kab uas hla (MFD) thiab lub reflector focal ntev (RFL):
Lub 1/e² txoj kab uas hla ntawm ib tug collimated beam yog kwv yees li:
Piv txwv li, siv RCR25A-P01 me me collimator rau collimate P3-630A-FC-1 ib hom fiber ntau, ntawm lub wavelength ntawm λ = 633 nm, MFD yog 4.3µm.
Ob qhov sib npaug saum toj no qhia tau tias qhov sib txawv ntawm lub kaum sab xis yog 0.01 degrees, thiab txoj kab uas hla yog 4.8 mm.
Multimode Fiber Collimation
Tag nrho cov divergence lub kaum sab xis ntawm ib tug collimated beam yog kwv yees li:
Txoj kab uas hla ntawm txoj kab sib tsoo yog kwv yees li:
Cov zis ntawm multimode fiber ntau feem ntau tsis zoo collimated.
Raws li cov qauv saum toj no, txoj kab nruab nrab ntawm lub beam feem ntau cuam tshuam los ntawm NAntawm ib txoj hauj lwm ze rau OAP reflector, tab sis raws li lub beam propagates, lubkev cuam tshuam ntawm cov tub ntxhais txoj kab uas hla yuav ntau thiab ntau pom tseeb.
Rau lub taag collimator hais los saum toj no, lub collimated beam txoj kab uas hla yogxam los ntawm 2NA * RFL, uas yog ntau tshaj 1/e² beam txoj kab uas hla.
Thaum xaiv ib tug taag collimator, lub focal ntev yuav inferred los ntawm lubyuav tsum tau beam txoj kab uas hla los txiav txim tus qauv tsim nyog.
Muaj ob qhov kev txwv tseem ceeb rau kev sib koom ua ke multimode fibers.
Ua ntej, feem ntau multimode fibers muaj qhov sib txawv ntawm cov zis tawm uas tuaj yeem ua tauthaiv los ntawm cov vaj tse ua ntej mus txog OAP reflector, yog li cov fiber ntau NAtsis tuaj yeem tshaj tus nqi; saib cov lus dhau los kom paub meej.
Qhov thib ob, qhov sib txawv ntawm cov kab sib tsoo yog cuam tshuam nrog lub hauv paustxoj kab uas hla; raws li cov tub ntxhais txoj kab uas hla nce, qhov siab tshaj NA txhawb nqa los ntawmlub collimator txo.
Yog hais tias lub collimated beam txoj kab uas hla tshaj lub meej aperture, cov zisbeam yuav thaiv los ntawm lub tsev.
Ob qho xwm txheej no tuaj yeem ua rau txo qis beam zoo.
Tsis tas li ntawd, OAP reflectors tsuas tuaj yeem sib txuas cov ntsiab lus zoo kawg nkaus ntawm qhovfocal point.
Qhov ntau dua qhov sib txawv ntawm qhov point qhov chaw los ntawm optical axis, los yogloj dua lub multimode core txoj kab uas hla, qhov ntau dua qhov distortion ntawm collimatednqaj; nce lub reflection focal ntev los yog wavelength yuav txo tau covdistortion.
