N-BK7 (CDGM H-K9L)
Lenses Foomka ugu Wanaagsan

Muraayadaha wareegsan, dhererka fooxa ee la bixiyay waxaa lagu qeexi karaa in ka badan hal isku darka hore iyo gadaal ee curvature.Isku darka kasta oo qaloocyada dusha sare ah ayaa keeni doona qadar kala duwan oo aberration ah oo uu keeno muraayadda.Wareegga qallooca ee dusha kasta ee muraayadaha qaabka ugu fiican ayaa loo qaabeeyey si loo yareeyo soo jiidashada wareega iyo koomada ay soo saarto muraayadda, iyada oo loo wanaajinayo isticmaalka isku-xireyaasha aan dhammaadka lahayn.Habkani wuxuu muraayadahani ka dhigayaa mid ka qaalisan muraayadaha plano-convex ama laba-convex lenses, laakiin wali si aad ah uga qaalisan khadkeena caymiska ee lenses aspheric ama achromats ee CNC.

Maadaama muraayadaha lagu hagaajiyay cabbirka booska ugu yar, waxay aragti ahaan gaari karaan waxqabadka xaddidan ee kala-duwanaanshaha dhexroorka alwaaxyada yar-yar.Si loo helo waxqabadka ugu wanaagsan ee diiradda saaraya codsiyada, dhig dusha sare leh raadiyaha gaagaaban ee qalooca (ie, oogada aadka u liidata) ee u jeedda isha isku xidhan.

Paralight Optics waxay bixisaa N-BK7 (CDGM H-K9L) Lenses Foomka ugu Wanaagsan kuwaas oo loogu talagalay inay yareeyaan aberration spherical iyadoo weli la isticmaalayo dusha wareegsan si ay u sameeyaan muraayada.Waxaa sida caadiga ah loo adeegsadaa isku-xireyaasha aan dhammaadka lahayn ee codsiyada awoodda sare leh halkaas oo laba-jibbaaran aysan ahayn ikhtiyaar.Muraayadaha ayaa la heli karaa mid aan dahaadhnayn ama dahaarkeena lidka-milicsiga (AR) ee lagu kaydiyo labada dusha si loo yareeyo iftiinka ka muuqda oog kasta oo muraayadda si loo yareeyo cadadka iftiinka ka muuqda dusha kasta oo muraayadda.Dahaarkan AR waxaa loo habeeyay cabbirka muuqaalka ee 350 – 700 nm (VIS), 650 – 1050 nm (NIR), 1050 – 1700 nm (IR).Dahaarkani wuxuu si weyn u yareynayaa milicsiga sare ee substrate-ka oo ka yar 0.5% dusha sare, taasoo keenaysa gudbinta celceliska sare ee dhammaan noocyada daahan AR.Ka eeg jaantusyada soo socda tixraacyadaada.
