Broadband AR Yokutidwa ndi Ma Lens a Achromatic
Mafotokozedwe Akatundu
Ma lens a Achromatic ndi mitundu ya magalasi omwe amapangidwa kuti achepetse kusintha kwa chromatic, lomwe ndi vuto lomwe limafala lomwe limapangitsa kuti mitundu iwonekere mosiyana ikadutsa pa disolo. Ma lenswa amagwiritsa ntchito zinthu ziwiri kapena zingapo zowoneka bwino zokhala ndi ma refractive indices kuti aziyang'ana mafunde osiyanasiyana a kuwala pamalo amodzi, zomwe zimapangitsa kuti kuwala koyera kukhale kolunjika kwambiri. Magalasi a Achromatic amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana monga kujambula, microscope, telescopes, ndi ma binoculars. Amathandizira kukonza chithunzicho pochepetsa malire amitundu ndikupanga zithunzi zolondola komanso zakuthwa. Amagwiritsidwanso ntchito kwambiri pamakina a laser ndi zida zowonera zomwe zimafunikira kulondola komanso kumveka bwino monga zida zamankhwala, ma spectrometer, ndi zida zakuthambo.
Broadband AR Coated Achromatic Lenses ndi ma lens owoneka bwino omwe amapereka luso lazithunzithunzi zapamwamba pamafunde osiyanasiyana opepuka. Ma lens awa ndi abwino kwa ntchito zingapo kuphatikiza kafukufuku wasayansi, kujambula kwachipatala ndiukadaulo wazamlengalenga.
Ndiye kodi ma lens a burodibandi a AR okutidwa ndi achromatic ndi chiyani? Mwachidule, adapangidwa kuti athetse mavuto a chromatic aberration ndi kutayika kwa kuwala komwe kungachitike pamene kuwala kumatsutsidwa ndi magalasi achikhalidwe. Chromatic aberration ndi kusokonekera kwa zithunzi komwe kumachitika chifukwa cha kulephera kwa lens kuyang'ana mitundu yonse ya kuwala pamalo amodzi. Magalasi a Achromatic amathetsa vutoli pogwiritsa ntchito magalasi amitundu iwiri (nthawi zambiri galasi la korona ndi galasi lamwala) kuti apange lens imodzi yomwe imatha kuyang'ana mitundu yonse ya kuwala panthawi yomweyi, zomwe zimapangitsa kuti pakhale chithunzi chomveka komanso chakuthwa.
Koma ma lens achromatic nthawi zambiri amavutika ndi kutayika kwa kuwala chifukwa cha zowunikira kuchokera pamwamba pa mandala. Apa ndipamene zokutira za Broadband AR zimabwera. Chophimba cha AR (anti-reflective) ndi chinthu chochepa kwambiri chomwe chimayikidwa pamwamba pa lens chomwe chimathandiza kuchepetsa kunyezimira ndikuwonjezera kuchuluka kwa kuwala komwe kumafalitsidwa kudzera mu lens. Zopaka za Broadband AR zimayenda bwino pa zokutira zofananira za AR polola kufalikira kwa kuwala kupitilira muyeso wokulirapo wa mafunde.
Pamodzi, ma lens achromatic ndi zokutira za Broadband AR zimapereka mawonekedwe amphamvu omwe amatha kupititsa patsogolo magwiridwe antchito osiyanasiyana. Amagwiritsidwa ntchito m'chilichonse kuyambira ma spectrometer mpaka ma telescopes komanso makina a laser. Chifukwa cha kuthekera kwawo kufalitsa kuwala kochuluka kudera lonse, magalasiwa amapereka chithunzi chakuthwa, chapamwamba kwambiri m'malo osiyanasiyana ndi kagwiritsidwe ntchito.
Broadband AR-coated achromatic lens ndi njira yamphamvu yowunikira yomwe imatha kupereka chithunzithunzi chapamwamba pamitundu yosiyanasiyana ya mafunde. Pamene zipangizo zamakono zikupitabe patsogolo, mosakayika magalasi amenewa adzakhala ndi mbali yofunika kwambiri pa kafukufuku wa sayansi, kujambula zithunzi zachipatala, ndi ntchito zina zambiri.
