Silicon (Si)
Plano-Convex Lenses

Plano-convex (PCX) lo ntsiab muag muaj qhov ntev focal ntev thiab tuaj yeem siv los ua kom pom lub teeb sib sib zog nqus mus rau tom qab focal point, kom sib tsoo lub teeb los ntawm qhov chaw taw tes, lossis txo qhov sib txawv ntawm qhov sib txawv.Txhawm rau txo qhov kev taw qhia ntawm qhov sib txawv ntawm qhov sib txawv, lub teeb pom kev sib txuam yuav tsum yog qhov xwm txheej ntawm qhov nkhaus ntawm lub lens thaum siv PCX los tsom rau qhov teeb pom kev sib tsoo;Ib yam li ntawd, qhov sib txawv ntawm lub teeb pom kev zoo yuav tsum yog qhov xwm txheej ntawm qhov chaw ntawm lub lens PCX thaum sib sau ua ke qhov chaw ntawm lub teeb.Cov lo ntsiab muag no yog siv nyob rau hauv infinite thiab finite conjugate daim ntaub ntawv.

Thaum txiav txim siab ntawm lub lens-convex thiab lub lens bi-convex, ob qho tib si uas ua rau lub teeb pom kev sib tsoo, feem ntau yog tsim nyog xaiv lub lens plano-convex yog tias qhov xav tau qhov kev nthuav dav yog tsawg dua 0.2 lossis ntau dua. 5. Nyob nruab nrab ntawm ob qhov tseem ceeb no, cov lo ntsiab muag bi-convex feem ntau nyiam.

Silicon muaj thermal conductivity thiab tsawg ntom.Txawm li cas los xij nws muaj qhov nqus tau zoo ntawm 9 microns, nws tsis haum rau siv nrog CO2 laser kis tau tus mob daim ntawv thov.Paralight Optics muaj Silicon (Si) Plano-Convex Lenses muaj nrog broadband AR txheej optimized rau 3 µm txog 5 μm spectral ntau yam tso rau ntawm ob qhov chaw.Cov txheej no zoo heev txo qhov kev xav ntawm lub substrate, yielding siab kis tau tus mob thiab tsawg haum rau tag nrho AR txheej ntau yam.Xyuas cov Graphs rau koj cov ntaub ntawv siv.
