Broadband AR Coated Achromatic Lenses
Ingcaciso yeMveliso
Iilensi ze-Achromatic ziintlobo zeelensi ezenzelwe ukunciphisa i-chromatic aberration, eyingxaki eqhelekileyo yamehlo ebangela ukuba imibala ibonakale ngokwahlukileyo xa idlula kwilensi.Ezi lens zisebenzisa indibaniselwano yezinto ezimbini okanye ngaphezulu ze-optical indices ezine-refractive indices ukuze zigxininise ubude bamaza okukhanya kwindawo enye, nto leyo ekhokelela ekugxininiseni okubukhali kokukhanya okumhlophe.Iilensi zeAchromatic zisetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo ezinje ngokufota, imicroscope, iteleskopu, kunye neebinotyhulasi.Banceda ukuphucula umgangatho womfanekiso ngokunciphisa imiphetho yemibala kunye nokuvelisa imifanekiso echanekileyo kunye nebukhali.Zikwasetyenziswa ngokuqhelekileyo kwiinkqubo ze-laser kunye nezixhobo ze-optical ezifuna ukuchaneka okuphezulu kunye nokucaca okufana nezixhobo zonyango, i-spectrometers, kunye nezixhobo ze-astronomy.
I-Broadband AR Coated Achromatic Lenses ziilensi zamehlo ezibonelela ngesakhono sokucinga esikumgangatho ophezulu kuluhlu olubanzi lwamaza okukhanya.Ezi lens zifanelekile kuluhlu lwezicelo ezibandakanya uphando lwezenzululwazi, umfanekiso wezonyango kunye nobuchwepheshe be-aerospace.
Ke yintoni kanye kanye ibroadband AR coated achromatic lens?Ngamafutshane, zenzelwe ukusombulula iingxaki ze-chromatic aberration kunye nokulahleka kokukhanya okunokuthi kwenzeke xa ukukhanya kuhlanjululwa ngeelensi zendabuko.I-Chromatic aberration kukugqwethwa komfanekiso okubangelwa kukungakwazi kwelensi ukugxila kuyo yonke imibala yokukhanya kwindawo enye.Iilensi ze-Achromatic zixazulula le ngxaki ngokusebenzisa iindidi ezimbini zeglasi (ngokuqhelekileyo iglasi yesithsaba kunye neglasi ye-flint) ukudala i-lens enye enokuthi igxininise yonke imibala yokukhanya kwinqanaba elifanayo, elibangela umfanekiso ocacileyo kunye obukhali.
Kodwa iilensi ze-achromatic zihlala zinengxaki yokulahleka kokukhanya ngenxa yokubonakaliswa komphezulu welensi.Yilapho i-Broadband AR i-coatings ingena khona. I-AR (i-anti-reflective) i-coating yi-maleko encinci yezinto ezifakwe kumphezulu we-lens onceda ukunciphisa ukubonakaliswa kunye nokwandisa umthamo wokukhanya okuhanjiswa nge-lens.Iingubo ze-Broadband AR ziphucula kwiingubo eziqhelekileyo ze-AR ngokuvumela ukuhanjiswa okungcono kokukhanya kuluhlu olubanzi lwamaza amaza.
Ngokudibeneyo, i-achromatic lens kunye ne-Broadband AR yokwambathisa ibonelela ngenkqubo enamandla yokubona enokuphucula ukusebenza kuluhlu olubanzi lwezicelo.Zisetyenziswa kuyo yonke into ukusuka kwii-spectrometers ukuya kwiiteleskopu kunye neenkqubo zelaser.Ngenxa yokukwazi ukuhambisa ipesenti ephezulu yokukhanya kwi-spectrum ebanzi, ezi lens zibonelela ngemifanekiso ebukhali, ekumgangatho ophezulu kwiindawo ezahlukeneyo kunye nokusetyenziswa.
I-Broadband AR-coated achromatic lens yinkqubo enamandla ye-optical enokubonelela ngemifanekiso esemgangathweni ophezulu kuluhlu olubanzi lwamaza okukhanya.Njengoko ubugcisa buqhubeka bukhula, ngokungathandabuzekiyo ezi lens ziya kuba nendima ebalulekileyo kuphando lwenzululwazi, umfanekiso wezonyango, nezinye izinto ezininzi ezinokusetyenziswa.
