I. Isimiso Samalensi E-Photochromic
Emphakathini wanamuhla, njengoba ukungcola komoya kuya ngokuya kuba kubi futhi ungqimba lwe-ozone lonakala kancane kancane, izibuko zamehlo zivame ukuchayeka elangeni elinothile nge-UV. Amalensi e-photochromic aqukethe ama-microcrystals e-photochromic agents—i-silver halide kanye ne-copper oxide. Uma echayeka ekukhanyeni okunamandla, i-silver halide iyabola ibe yisiliva kanye ne-bromine; amakristalu amancane esiliva akhiwe kule nqubo aguqula amalensi abe nsundu ngokumnyama. Lapho ukukhanya kunyamalala, isiliva kanye ne-bromine kuhlangana kabusha kube yi-silver halide ngaphansi kwesenzo se-catalytic se-copper oxide, okukhanyisa amalensi futhi.
Uma amalensi e-photochromic evezwa emisebeni ye-ultraviolet (UV), ungqimba lwawo luba mnyama ngokushesha ngenkathi luvimba ukungena kwe-UV, okuvimbela kakhulu i-UVA ne-UVB ukuthi zingalimazi amehlo. Emazweni athuthukile, amalensi e-photochromic sekuyisikhathi eside eqashelwa ngabathengi abaqaphela impilo ngezinzuzo zawo zezempilo, ukulula kwawo, kanye nobuhle bawo. Ukukhula kwaminyaka yonke kwenani labathengi abakhetha amalensi e-photochromic kufinyelele izinombolo eziphindwe kabili.
II. Izinguquko Zombala Zamalensi E-Photochromic
Ngezinsuku ezinelanga: Ekuseni, umoya unefu elincane, elivimbela i-UV encane, okuvumela imisebe eminingi ye-UV ukuthi ifinyelele phansi. Ngenxa yalokho, amalensi e-photochromic aba mnyama kakhulu ekuseni. Kusihlwa, amandla e-UV ayancipha—lokhu kungenxa yokuthi ilanga likude nomhlabathi, futhi inkungu eqongelela emini ivimba imisebe eminingi ye-UV. Ngakho-ke, umbala wamalensi uba mhlophe kakhulu ngalesi sikhathi.
Ngezinsuku ezinamafu: imisebe ye-UV isakwazi ukufinyelela phansi ngamandla amakhulu ngezinye izikhathi, ngakho-ke amalensi e-photochromic azoba mnyama. Ngaphakathi, ahlala ecacile cishe futhi enombala omncane noma angabi nawo nhlobo umbala. Lawa malensi ahlinzeka ngokuvikelwa okuhle kakhulu kwe-UV kanye nokukhanya kunoma iyiphi indawo, elungisa umbala wawo ngokushesha ngokusekelwe ezimweni zokukhanya. Ngenkathi evikela ukubona, ahlinzeka ngokuvikelwa kwempilo yamehlo yonke indawo noma nini, noma kuphi.
Ubuhlobo nokushisa: Ngaphansi kwezimo ezifanayo, njengoba izinga lokushisa likhuphuka, umbala wamalensi e-photochromic ukhanya kancane kancane; ngokuphambene nalokho, lapho izinga lokushisa lehla, amalensi amnyama kancane. Lokhu kuchaza ukuthi kungani umbala ukhanya ehlobo futhi umnyama ebusika.
Ijubane lokushintsha kombala kanye nokujula kombala nakho kuhlobene ngandlela thile nobukhulu belensi.
