Germanium (zeeg)
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, txhawm rau txhawm rau qhov chaw taw tes, lossis txo qhov sib txawv ntawm qhov sib txawv.Thaum cov duab zoo tsis yog qhov tseem ceeb, cov lo ntsiab muag plano-convex kuj tuaj yeem siv los hloov cov achromatic doublets.Yuav kom txo qis qhov kev taw qhia ntawm kheej kheej aberration, lub teeb pom kev sib tsoo yuav tsum yog qhov xwm txheej ntawm qhov nkhaus ntawm lub lens thaum raug tsom;Ib yam li ntawd, ib qho chaw teeb pom kev zoo yuav tsum yog qhov xwm txheej ntawm lub phiaj xwm txheej thaum raug sib tsoo.

Thaum txiav txim siab ntawm lub teeb pom kev zoo thiab lub lens bi-convex, ob qho tib si uas ua rau lub teeb pom kev sib tsoo, feem ntau nws yog qhov zoo dua los xaiv lub lens plano-convex yog tias qhov xav tau qhov magnification 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 dua.

Vim nws txoj kev sib kis dav dav (2 - 16 µm) thiab cov khoom siv tshuaj ruaj khov, Germanium yog qhov zoo rau kev siv IR laser, nws zoo heev rau kev ruaj ntseg, kev ua tub rog thiab kev siv duab.Txawm li cas los Ge's kis tau tus mob yog qhov kub thiab txias;Qhov tseeb, qhov nqus tau dhau los ua qhov loj heev uas cov germanium yuav luag opaque ntawm 100 ° C thiab tsis-transmissive ntawm 200 ° C.
Paralight Optics muaj Germanium (Ge) Plano-convex (PCX) Lenses muaj nrog broadband AR txheej rau 8 µm txog 12 μm spectral ntau yam tso rau ntawm ob qhov chaw.Cov txheej no zoo heev txo qhov siab ntawm qhov pom ntawm lub substrate, ua rau qhov nruab nrab kis tau tus mob ntau dua 97% dhau ntawm tag nrho AR txheej.Xyuas cov Graphs rau koj cov ntaub ntawv siv.
