N-BK7 (CDGM H-K9L)
Muraayadaha Bi-Convex
N-BK7 waa muraayadda muraayadda indhaha ee borosilicate oo si ballaaran loogu isticmaalo muuqaalka iyo NIR spectrum, waxaa sida caadiga ah la doortaa mar kasta oo faa'iidooyinka dheeraadka ah ee UV-ga silica ah (ie, gudbinta wanaagsan ee UV iyo kororka hoose ee ballaarinta kulaylka) maaha lagama maarmaan.Waxaan u isticmaalnaa qalab u dhigma Shiinaha CDGM H-K9L si aan ugu bedelno N-BK7.
Paralight Optics waxay bixisaa muraayadaha N-BK7 (CDGM H-K9L) Bi-Convex oo leh ikhtiyaaro ah kuwa aan dahaarka lahayn ama kuwa ka-hortagga milicsiga (AR), kaas oo yareynaya cadadka iftiinka ee ka muuqda dusha kasta oo muraayadda.Maaddaama ku dhawaad 4% ee iftiinka dhacdada uu ka muuqdo dusha kasta oo ka mid ah substrate-ka aan la daboolin, codsigayaga dahaarka AR ee waxqabadka sare leh ee lakabka badan wuxuu hagaajiyaa gudbinta, taas oo muhiim u ah codsiyada iftiinka hooseeya, waxayna ka hortagtaa saameynta aan loo baahnayn (tusaale, sawirada rooxaanta) oo la xidhiidha milicsi badan.Lahaanshaha indho-indheyn leh dahaarka AR ee loo habeeyay cabbirka muuqaalka ah ee 350 – 700 nm, 650 – 1050 nm, 1050 – 1700 nm oo lagu kaydiyay labada dusha sare.Dahaarkani wuxuu si weyn u yareynayaa milicsiga sare ee substrate-ka in ka yar 0.5% dusha sare, taasoo keenaysa gudbinta celceliska sare ee dhammaan kala duwanaanta daahan AR ee xaglaha dhacdooyinka (AOL) inta u dhaxaysa 0 ° iyo 30 ° (0.5 NA), Waayo, indhaha loogu talagalay si loogu isticmaalo xaglaha shilalka waaweyn, tixgeli isticmaalka dahaarka gaarka ah ee lagu hagaajiyay xagal 45° ee dhacdada;daahan caadadu waxay wax ku ool u tahay 25 ° ilaa 52 °.Dahaarka Broadband waxay leeyihiin nuugista caadiga ah ee 0.25%.Ka eeg jaantusyada soo socda tixraacyadaada.
