Cylindrical Lenses
Qhov zoo cylindrical lo ntsiab muag muaj ib qho chaw tiaj tus thiab ib qho chaw convex, lawv yog qhov zoo tagnrho rau cov ntawv thov kom muaj qhov loj me hauv ib qhov ntev. Thaum cov lo ntsiab muag kheej kheej ua symmetrically nyob rau hauv ob qhov ntev ntawm qhov teeb meem hluav taws xob, cylindrical lo ntsiab muag ua tib yam nkaus tab sis tsuas yog hauv ib qhov ntev. Ib daim ntawv thov raug siv yuav yog siv ob lub cylindrical lo ntsiab muag los muab anamorphic shaping ntawm lub nqaj. Lwm daim ntawv thov yog siv ib qho zoo cylindrical lo ntsiab muag kom pom qhov sib txawv ntawm cov nqaj mus rau qhov chaw kuaj pom; Ib khub ntawm qhov zoo cylindrical lo ntsiab muag tuaj yeem siv los sib sau ua ke thiab ncig cov zis ntawm lub laser diode. Txhawm rau txo qhov kev taw qhia ntawm qhov sib txawv ntawm qhov sib txawv, lub teeb sib tsoo yuav tsum tshwm sim ntawm qhov chaw nkhaus thaum tsom mus rau ib txoj kab, thiab lub teeb los ntawm ib qho kab yuav tsum yog qhov xwm txheej ntawm lub ntsej muag thaum sib tsoo.
Cov lo ntsiab muag tsis zoo cylindrical muaj ib qho chaw tiaj tus thiab ib qho concave nto, lawv muaj qhov tsis zoo focal ntev thiab ua raws li lub hom phiaj ntawm lub ntsej muag kheej kheej, tsuas yog ntawm ib qho axis xwb. Cov lo ntsiab muag no yog siv rau hauv daim ntawv thov uas xav tau ib qhov loj me ntawm lub teeb ci. Ib daim ntawv thov raug siv yuav yog siv ib qho tsis zoo cylindrical lens los hloov lub laser collimated rau hauv kab generator. Cov khub ntawm lub cylindrical lo ntsiab muag tuaj yeem siv los ua cov duab anamorphically. Txhawm rau txo qhov kev taw qhia ntawm aberration, qhov nkhaus ntawm lub lens yuav tsum fim lub hauv paus thaum siv los sib faib ib lub teeb.
Paralight Optics muaj cylindrical lo ntsiab muag fabricated nrog N-BK7 (CDGM H-K9L), UV-fused silica, los yog CaF2, tag nrho cov uas muaj uncoated los yog antireflection txheej. Peb kuj tseem muab cov qauv hloov pauv ntawm peb lub cylindrical lo ntsiab muag, rod lo ntsiab muag, thiab cylindrical achromatic doublets rau daim ntawv thov uas yuav tsum tau muaj tsawg kawg nkaus aberration.
