Isistimu yokubona, esetshenziswa kakhulu ekuthwebuleni nasekutholeni uhlelo lokulinganisa.Isetshenziselwa kakhulu ukuthwebula izithombe ezijulile zolwandle ezithombeni.Izinto zengilazi zingakwazi ukumelana nokucindezela kwamanzi okwanele futhi aziguquki ngenxa yezinto ze-acrylic.Ngaphezu kwalokho, ukudluliswa kokukhanya kwengilazi, amabhamuza nemithende yezinto ngokwazo, kanye nokushelela nobulukhuni bendawo ngokwayo kwenza ukuhlola okujulile kolwandle kulangazelele ukukhetha idome lengilazi.Futhi isetshenziselwa ukutholwa komkhathi, i-pyranometer.Izindawo ezimbili ezicishe zilingane zivimbela ukukhanya ukuthi kunqanyulwe kakhulu lapho kudlula ingxenye, ngaleyo ndlela kuqinisekiswe ukuthi amandla awalahleki futhi kuthuthukisa ukunemba kwesilinganiso.
Ama-Optical dome amawindi ane-hemispheric ahlinzeka ngomngcele ovikelayo kuyilapho evumela inkambu ecacile yokubuka phakathi kwezindawo ezimbili.Ngokuvamile zenziwe ngezindawo ezimbili ezifanayo.I-DG Optics ikhiqiza ama-optical dome ezinhlobonhlobo zama-substrates, alungele ukubonakala, i-IR, noma ukukhanya kwe-UV.Amadomu ethu atholakala ngosayizi ukusuka ku-10 mm kuya ngaphezu kuka-350 mm ububanzi, nosayizi ngokwezifiso abangenzeka uma uwacela.
I-BK7 noma i-silica ehlanganisiwe iyisinqumo esihle sedome elibonakalayo elizosetshenziswa ezimeni lapho ukukhanya okubonakalayo kuphela kufanele kudluliswe;isibonelo, kunzwa yekhamera noma izinhlelo zokusebenza ze-meteorology.I-BK7 inokuqina okuhle kwamakhemikhali, futhi inikeza ukudluliswa okuhle kakhulu kwebanga le-wavelength elingu-300nmto 2µm.
Ngokudluliswa kokukhanya kwebanga le-UV, isilika ehlanganisiwe yezinga le-UV iyatholakala.Amadome ethu e-silica ahlanganisiwe angamelana nengcindezi ephezulu futhi alungele ukusetshenziswa ngaphansi kwamanzi.Le ngilazi ebonakalayo ihlinzeka ngokudluliswa kwamaphesenti angaphezu kwama-85 kumaza wamaza afika ku-185 nm.
