Amalensi e-Broadband AR ehlanganisiwe ama-achromatic lens
Ukuchazwa Komkhiqizo
Amalensi e-Achromatic izinhlobo zama-lens aklanyelwe ukunciphisa i-chromatic abrrrration, okuyinkinga evamile ebonakalayo ebangela ukuthi imibala ivele ngendlela ehlukile lapho idlula ngelensi. Lawa ma-lens asebenzisa inhlanganisela yezinto ezimbili noma ngaphezulu ze-optical ezinama-indices ahlukene okuthi agxile kuma-wavelength ahlukile endaweni efanayo, okuholela ekugxileni okubukhali kokukhanya okumhlophe. Amalensi e-Achromatic asetshenziswa kabanzi ezinhlotsheni ezahlukahlukene ezifana nokuthwebula izithombe, microscopy, telescopes, kanye nama-binoculars. Basiza ukuthuthukisa ikhwalithi yesithombe ngokunciphisa ama-fringes anemibala futhi kukhiqize izithombe ezinembile futhi ezibukhali. Zivame ukusetshenziswa ezinhlelweni ze-laser kanye nezinsimbi zokubona ezidinga ukunemba okuphezulu nokucaca okufana nezinsimbi zezokwelapha, ama-spectrometer, nemishini yezinkanyezi, nemishini yezinkanyezi.
Amalensi we-Broadband AR ehlanganiswe ama-achromatic ama-lens abonakalayo ahlinzeka ngamakhono aphezulu wokucabanga ahlukahlukene ngaphezulu kwama-wavelength alula ahlukahlukene. Lawa ma-lens alungele ukwahlulela kwezicelo ezibandakanya ucwaningo lwesayensi, ukucabanga kwezokwelapha kanye nobuchwepheshe be-aerospace.
Manje yini ngempela ilensi ebanzi ye-ar cante? Ngamafuphi, zenzelwe ukuxazulula izinkinga ze-chromatic abrrration kanye nokulahleka okukhanyayo okungenzeka lapho ukukhanya kuvinjelwe ngamalensi endabuko. I-Chromatic Abrrrration ingukuhlanekezela isithombe okubangelwa ukungakwazi kwe-lens ukugxila kuyo yonke imibala yokukhanya ngesikhathi esifanayo. Amalensi e-Achromatic axazulula le nkinga ngokusebenzisa izinhlobo ezimbili ezihlukene zengilazi (imvamisa umqhele wengilazi kanye nengilazi ye-flint) ukudala ilensi eyodwa engagxila kuyo yonke imibala yokukhanya ngesikhathi esifanayo, okuholela esithombeni esicacile nesibukhali.
Kepha amalensi e-achromatic avame ukuhlushwa ukulahleka okukhanyayo ngenxa yokucabanga kusuka endaweni ye-lens. Yilapho izamboza ze-Broadband AR zingena. I-AR (Anti-Refecture) I-Coating ungqimba oluncane lwezinto ezisetshenziswayo ebusweni belensi elisiza ukunciphisa izinkomba futhi kwandise inani lokukhanya elidluliselwe ku-lens. I-Broadband AR Coatings Thuthukisa ku-Standard AR Coatings ngokuvumela ukudluliswa okungcono kokukhanya okungcono ngaphezulu kobubanzi be-wavelength.
Ngokubambisana, i-achromatic lens kanye ne-broadband ar coating ahlinzeke ngohlelo olunamandla lokubona olungathuthukisa ukusebenza ezinhlobonhlobo zezicelo. Zisetshenziswa kukho konke kusuka kuma-spectrometer kuya ezibonakudeni nasezinhlelweni ze-laser. Ngenxa yekhono labo lokudlulisela amaphesenti aphezulu okukhanya kulo lonke i-spectrum ebanzi, la malensi ahlinzeka ngemifanekiso ebukhali, esezingeni eliphakeme ezindaweni ezahlukahlukene kanye nezicelo.
Amalensi we-arromatic amnyama ahlanganisiwe we-achbac Njengoba ubuchwepheshe buyaqhubeka nokuvela, akungabazeki ukuthi la malensi azodlala indima ebaluleke kakhulu ocwaningweni lwesayensi, ukucabanga kwezokwelapha, kanye nezinye izinhlelo zokusebenza ezingenakubalwa.
