I-Broadband AR Coated Achromatic Lens
Incazelo Yomkhiqizo
Amalensi e-Achromatic ayizinhlobo zamalensi adizayinelwe ukunciphisa ukuphuma kwe-chromatic, okuyinkinga evamile yokubona eyenza imibala ibonakale ngendlela ehlukile uma idlula ilensi. Lawa ma-lens asebenzisa inhlanganisela yezinto ezimbili noma ngaphezulu ezibonakalayo ezinezinkomba ezihlukene zokugqamisa ukuze agxilise amaza ahlukene okukhanya endaweni efanayo, okuholela ekugxilweni okubukhali kokukhanya okumhlophe. Amalensi e-Achromatic asetshenziswa kabanzi ezinhlelweni ezahlukahlukene ezifana nokuthatha izithombe, i-microscopy, izibonakude, nama-binoculars. Basiza ukuthuthukisa ikhwalithi yesithombe ngokunciphisa amaphethelo ombala futhi bakhiqize izithombe ezinembe kakhulu nezibukhali. Asetshenziswa futhi kumasistimu we-laser namathuluzi okubona adinga ukunemba okuphezulu nokucaca okufana namathuluzi ezokwelapha, ama-spectrometer, kanye nemishini yezinkanyezi.
I-Broadband AR Coated Achromatic Lens amalensi okubona ahlinzeka ngamakhono wokuthwebula wekhwalithi ephezulu phezu kwebanga elibanzi lamaza okukhanya. Lawa ma-lens alungele uhla lwezinhlelo zokusebenza ezihlanganisa ucwaningo lwesayensi, izithombe zezokwelapha kanye nobuchwepheshe be-aerospace.
Ngakho-ke iyini ngempela i-broadband AR ehlanganiswe ilensi ye-achromatic? Ngamafuphi, aklanyelwe ukuxazulula izinkinga zokungalungi kwe-chromatic nokulahlekelwa ukukhanya okungenzeka lapho ukukhanya kuphikiswa ngamalensi endabuko. I-Chromatic aberration ukuhlanekezelwa kwesithombe okubangelwa ukungakwazi kwelensi ukugxilisa yonke imibala yokukhanya endaweni efanayo. Amalensi e-Achromatic axazulula le nkinga ngokusebenzisa izinhlobo ezimbili ezihlukene zengilazi (imvamisa ingilazi yomqhele kanye nengilazi ye-flint) ukuze enze ilensi eyodwa engagxilisa yonke imibala yokukhanya endaweni efanayo, okuholela esithombeni esicacile nesibukhali.
Kodwa amalensi e-achromatic ngokuvamile abhekana nokulahlekelwa ukukhanya ngenxa yokubonakala okuvela ebusweni be-lens. Yilapho kungena khona ama-Broadband AR ama-coatings. I-AR (anti-reflective) inamathela ungqimba oluncane lwento esetshenziswa phezu kwelensi esiza ukwehlisa ukukhanyela nokwandisa inani lokukhanya okudluliselwa ngelensi. Izembatho ze-Broadband AR ziyathuthuka ekuhlanganisweni kwe-AR okujwayelekile ngokuvumela ukudluliswa okungcono kokukhanya phezu kwebanga elibanzi lamaza wamaza.
Ndawonye, ilensi ye-achromatic kanye ne-broadband AR coating inikeza isistimu yokubona enamandla engathuthukisa ukusebenza kuhlelo olubanzi lwezinhlelo zokusebenza. Asetshenziswa kukho konke kusuka kuma-spectrometers kuya kuma-telescopes ngisho nezinhlelo ze-laser. Ngenxa yekhono lawo lokudlulisa iphesenti eliphezulu lokukhanya ku-spectrum ebanzi, lawa ma-lens ahlinzeka ngesithombe esibukhali, sekhwalithi ephezulu ezindaweni ezihlukahlukene kanye nezinhlelo zokusebenza.
I-Broadband AR-coated achromatic lens ayisistimu yokubona enamandla engahlinzeka ngesithombe sekhwalithi ephezulu phezu kwebanga elibanzi lamaza okukhanya. Njengoba ubuchwepheshe buqhubeka buthuthuka, ngokungangabazeki lawa ma-lens azodlala indima ebalulekile ocwaningweni lwesayensi, ekuthwebuleni izithombe zezokwelapha, nakwezinye izinto ezingenakubalwa.
