Zinc Selenide (ZnSe)
Bi-Convex Lenses

Bi-Convex los yog Ob-Convex (DCX) Cov Lens Spherical yog kheej kheej thiab muaj qhov zoo tib yam curvature ntawm ob sab ntawm lub lens, yog li lawv yog symmetric thiab muaj qhov zoo focal ntev. Ntawm chav tsev conjugation, coma thiab distortion tshem tawm vim qhov symmetry. Cov lo ntsiab muag no tuaj yeem siv los tsom cov teeb pom kev zoo thiab yog nrov rau ntau daim ntawv thov kev pom zoo.

Txawm hais tias Bi-convex lo ntsiab muag txo qis aberrations nyob rau hauv cov xwm txheej uas cov khoom thiab cov duab nyob deb yog sib npaug los yog ze li ntawm qhov sib npaug, thaum txiav txim siab ntawm ob-convex lossis DCX lens thiab lub lens-convex, ob qho tib si uas ua rau muaj teeb meem teeb meem sib txuas, nws yog feem ntau yog qhov zoo dua los xaiv lub lens bi-convex kom txo qis aberrations yog tias qhov sib piv ntawm cov khoom thiab cov duab nyob deb (qhov tseeb conjugate ratio) yog ntawm 5: 1 thiab 1: 5. Sab nraum qhov no, cov lo ntsiab muag plano-convex feem ntau nyiam.

ZnSe lo ntsiab muag yog qhov tshwj xeeb zoo rau kev siv nrog lub zog siab CO2 lasers. Paralight Optics muaj Zinc Selenide (ZnSe) Bi-Convex Lenses muaj nrog broadband AR txheej optimized rau 8 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. Tshawb xyuas cov duab hauv qab no rau koj cov ntaub ntawv siv.
