Plano-Convex Lenses

Plano-convex (PCX) lo ntsiab muag yog qhov zoo lo ntsiab muag uas yog tuab nyob rau hauv nruab nrab tshaj ntawm ntug, thaum collimated rays mus los ntawm lawv, lub teeb converges rau lub cev focal point.Plano-convex lo ntsiab muag muaj ib sab tiaj tus thiab ib sab nkhaus nrog lub vojvoog zoo ntawm curvature.Plano-Convex lo ntsiab muag muaj qhov zoo focal ntev thiab mus kom ze rau daim ntawv zoo tshaj plaws rau infinite thiab finite conjugate daim ntaub ntawv.Cov lo ntsiab muag no tsom ib txoj kab sib dhos rau sab nraub qaum thiab sib tsoo lub teeb los ntawm qhov chaw taw tes.Lawv yog tsim los nrog tsawg tus kheej kheej aberration thiab muaj ib tug focal ntev muab los ntawm:
f = R/(n-1),
qhov twg R yog lub vojvoog ntawm curvature ntawm qhov convex ntawm lub lens thiab n yog qhov ntsuas ntawm refraction.

Plano-convex lo ntsiab muag xa me me kheej kheej distortion thaum tsom ntawm infinity (thaum cov duab duab nyob deb thiab qhov sib piv ntawm qhov siab).Yog li ntawd lawv yog cov mus-rau lens hauv koob yees duab thiab telescopes.Qhov kev ua tau zoo tshaj plaws yog ua tiav thaum lub ntiaj teb ntog ntsej muag lub dav hlau focal xav tau, hauv lwm lo lus, lub ntsej muag nkhaus ntsib qhov teeb meem sib tsoo.Plano convex lo ntsiab muag yog ib qho kev xaiv zoo rau lub teeb collimation los yog tsom rau daim ntawv thov siv monochromatic illumination, hauv kev lag luam xws li kev lag luam, tshuaj, neeg hlau, lossis kev tiv thaiv.Lawv yog cov kev xaiv pheej yig rau kev thov rau daim ntawv thov vim lawv yooj yim rau fabricate.Raws li txoj cai ntawm tus ntiv tes xoo, cov lo ntsiab muag plano-convex ua tau zoo thaum cov khoom thiab cov duab nyob ntawm qhov sib piv ntawm qhov sib piv> 5: 1 lossis < 1: 5, yog li qhov sib txawv ntawm qhov sib txawv, coma thiab distortion raug txo.Thaum qhov xav tau qhov kev nthuav dav yog nyob nruab nrab ntawm ob qhov tseem ceeb no, Bi-convex lo ntsiab muag feem ntau tsim nyog.

ZnSe lo ntsiab muag feem ntau yog siv rau hauv IR imaging, biomedical, thiab kev siv tub rog, lawv zoo haum rau kev siv nrog high-power CO2 lasers vim tsis muaj kev nqus coefficient.Tsis tas li ntawd, lawv tuaj yeem muab kev sib kis txaus hauv cheeb tsam pom kom tso cai rau kev siv cov kab teeb liab liab.Paralight Optics muaj Zinc Selenide (ZnSe) Plano-Convex (PCV) Lenses muaj nrog broadband AR txheej optimized rau 2 µm - 13 μm lossis 4.5 - 7.5 μm lossis 8 - 12 μm spectral ntau tso rau ntawm ob qhov chaw.Cov txheej no zoo heev txo qhov nruab nrab qhov cuam tshuam ntawm cov substrate tsawg dua 3.5%, yielding qhov nruab nrab kis tau tus mob ntau tshaj 92% lossis 97% hla tag nrho AR txheej.Tshawb xyuas cov duab hauv qab no rau koj cov ntaub ntawv siv.
