N-BK7 (CDGM H-K9L)
Bi-Convex Lenses
N-BK7 is borosilicate korona optical girazi rinoshandiswa zvakanyanya mukuonekwa uye NIR spectrum, inowanzosarudzwa chero nguva iyo yakawedzerwa mabhenefiti eUV fused silica (kureva, kutapurirana kwakanaka kunowedzera muUV uye yakaderera coefficient yekuwedzera kupisa) isingakodzeri. Isu tinotadza kushandisa maChinese akaenzana zvinhu zveCDGM H-K9L kutsiva N-BK7.
Paralight Optics inopa N-BK7 (CDGM H-K9L) Bi-Convex lenses ine sarudzo dzeasina kuvharwa kana antireflection yedu (AR) machira, ayo anoderedza huwandu hwechiedza chinoratidzwa kubva kune yega yega pamusoro pelenzi. Sezvo inenge 4% yechiedza chechiitiko chinoratidzwa panzvimbo imwe neimwe ye substrate isina kuvharwa, kushandiswa kwepamusoro-soro ye-multi-layer AR coating inovandudza kutapurirana, iyo inokosha mukushandiswa kwechiedza chakaderera, uye inodzivirira migumisiro isingadikanwi (semuenzaniso, ghost mifananidzo) yakabatana neakawanda kuratidza. Kuve neoptics ine AR coatings yakagadziridzwa kune inotaridzika siyana ye350 - 700 nm, 650 - 1050 nm, 1050 - 1700 nm yakaiswa pane ese ari maviri. Uku kupfekedza kunoderedza zvakanyanya kutarisisa kwepamusoro kweiyo substrate isingasviki 0.5% pese pese, ichipa yakakwira avhareji yekufambisa mukati meiyo yese AR coating renji yemakona echiitiko (AOL) pakati pe0 ° uye 30 ° (0.5 NA), yeOptics inotarisirwa. kuti ishandiswe pamakona mahombe echiitiko, funga kushandisa coating yakagadziridzwa pakona ye45° yezviitiko; iyi tsika yekupfeka inoshanda kubva pa25 ° kusvika 52 °. Broadband coatings ine yakajairwa kutorwa kwe 0.25%. Tarisai maGrafu anotevera kune mareferensi ako.
