Zosefera za Absorptive/Reflective Neutral Density

Kachulukidwe ka kuwala (OD) amawonetsa cholepheretsa choperekedwa ndi fyuluta ya kuwala, mwachitsanzo, momwe imachepetsera mphamvu ya kuwala kwa mtengo wa zochitika. OD imagwirizana ndi kufalitsa. Kusankha fyuluta ya ND yokhala ndi kachulukidwe kakang'ono kapamwamba kumatanthawuza kutsitsa kutsika komanso kuyamwa kwakukulu kwa kuwala kwa chochitikacho. Pakufalikira kwamphamvu komanso kuyamwa kochepa, kachulukidwe kocheperako kangakhale koyenera. Mwachitsanzo, ngati fyuluta yokhala ndi OD ya 2 imapangitsa kuti pakhale mtengo wotumizira 0.01, izi zikutanthauza kuti fyulutayo imachepetsa mtengowo ku 1% ya mphamvu ya zochitikazo. Pali mitundu iwiri ya zosefera za ND: zosefera osalowerera ndale, zosefera zowoneka bwino.

Zosefera zathu za absorptive neutral density (ND) zimapezeka mosiyanasiyana ndi ma optical densities (OD) kuyambira 0.1 mpaka 8.0. Mosiyana ndi mawonekedwe awo onyezimira, azitsulo, fyuluta iliyonse ya ND imapangidwa kuchokera kugawo la galasi la Schott lomwe lasankhidwa kuti likhale lofanana ndi lathyathyathya m'dera lowoneka kuchokera 400 nm mpaka 650 nm.

Zosefera zosalowerera ndale zowoneka bwino zimapezeka ndi N-BK7 (CDGM H-K9L), UV Fused Silica (JGS 1), kapena gawo lapansi la Zinc Selenide m'mitundu yosiyanasiyana. Zosefera za N-BK7 (CDGM H-K9L) zimakhala ndi gawo la galasi la N-BK7 ndi zokutira zachitsulo (Inconel) zomwe zimayikidwa mbali imodzi, Inconel ndi alloy zitsulo zomwe zimatsimikizira kuyankha kowoneka bwino kuchokera ku UV kupita kufupi ndi IR; Zosefera za silika zophatikizika ndi UV zimakhala ndi gawo lapansi la UVFS ndi zokutira za nickel zomwe zimayikidwa mbali imodzi, zomwe zimapereka kuyankha kosawoneka bwino; Zosefera za ZnSe zosalowerera ndale zimakhala ndi gawo laling'ono la ZnSe (kachulukidwe ka kuwala koyambira pa 0.3 mpaka 3.0) wokhala ndi zokutira faifi kumbali imodzi, zomwe zimatsogolera kukuyankhidwa kosawoneka bwino pamtunda wa 2 mpaka 16 µm kutalika kwa mawonekedwe, chonde onani chithunzi chotsatira pa maumboni anu.
