Hauv lub ntiaj teb ntawm lasers, txhim kho qhov zoo thiab precision ntawm lub teeb yog qhov tseem ceeb rau ntau cov ntawv thov xws li metrology rau cov txheej txheem kho mob. Ib qho tseem ceeb tshaj plaws siv rau kev txhim kho cov nqaj zoo yog qhov 'nqaj nthuav dav'.
Ib tug nqaj nthuav dav yog lub teeb ci kho qhov muag ntawm lub teeb thiab nthuav nws lub cheeb (nqaj divergence) thaum ib txhij txo nws cov nqaj divergence. Cov versatility ntawm cov nqaj nthuav tawm cov lus dag nyob rau hauv nws lub peev xwm los kho thiab tswj lub divergence ntawm lasers, txhim kho nws txoj kev sib hlub.
Cov Hom Beam Expanders
Muaj feem ntau ob hom nqaj nqaj nthuav dav: tsau thiab kho cov nqaj hlau nthuav dav.
1, tsau Beam expander - raws li lub npe qhia tau tswj lub nqaj sib txawv nrog cov lo ntsiab muag sib luag ntawm ob lub lo lo ntsiab muag sab hauv qhov expander. Qhov no tshwj xeeb yog ntseeg tau zoo rau cov ntawv thov uas muaj nyob ruaj khov, tswj ib puag ncig uas tsis tsim nyog lossis tsis tsim nyog.
2, Cov nqaj hlau tau nthuav tawm - nyob rau hauv cov ntsiab lus ntawm ob lub lo ntsiab muag tuaj yeem hloov kho, cia cov neeg siv kom zoo lub nqaj divergence raws li xav tau. Cov yam ntxwv no muaj nce ntxiv thiab hloov kho rau cov ntawv thov nrog cov kev xav tau.
Cov khoom siv thiab nthwv cua sib xyaw
Lub lens ntawm lub nqaj expander yog feem ntau ua los ntawm cov zese (zinc selenenide), cov khoom siv kho tshiab uas tso cai rau lub teeb liab kom dhau mus. Tab sis nws tseem ceeb yog qhov dav dua qhov no. Cov nqaj hlau nthuav dav tuaj yeem ua haujlwm ntawm ntau lub wavelengths, surmounting qhov kev txwv ntawm spectral ntau.
Piv txwv li, Carmanhaas muaj peb hom beam nqaj nthuav dav nrog ib qho zoo nkauj ntawm UV (1030NM), nyob ze-infrared (9.2-9.7um), kom deb-infrared (10.6um). Dab tsi yog cov captivating no yog tias lawv kuj muab kev cai ci ci nthuav dav nthuav tawm wavelengths raws li kev thov.

Seb nws yog qhov chaw ruaj lossis kho cov nqaj ua qhov chaw tseem ceeb hauv kev hloov pauv thiab coj cov kab teeb laser rau ntau cov ntawv thov. Thaum lub sij hawm taag beam expanders muaj lawv cov txiaj ntsig nyob rau hauv ib puag ncig ib puag ncig, kho beametable beam nthuav dav uas muaj kev hloov pauv ntawm dynamically hloov scenarios. Dab tsi yog cov ntsiab lus teb, cov khoom siv no tau nyab xeeb lawv txoj haujlwm yog qhov kev ua si uas tseem ceeb hauv cov tshuab laser.
Nrog rau cov kev siv nyiaj ntau ntxiv hauv cov lasers hauv ntau daim teb, qhov kev thov rau kev tshwj xeeb thiab customizable beam nthuav dav yuav muaj nyob rau xyoo tom ntej. Thiab kom cerable rau qhov kev thov no nce, cov tuam txhab zoo li Carmanhaas ib txwm mus txog qhov kev sib tw.
