N-BK7 (CDGM H-K9L)
Yakanakisa Form Spherical Lenses
Sezvo malenzi akagadziridzwa kweudiki saizi yenzvimbo, anogona ne theoretically kusvika diffraction-zvishoma kuita kwemadhayamita madiki ekupinza.Kuti uite zvakanakisa mukutarisisa maapplications, isa pamusoro neradius ipfupi yekumisikidza (kureva, iyo yakanyanya kukwirisa nzvimbo yakakombama) yakananga kunzvimbo yakasanganiswa.
Paralight Optics inopa N-BK7 (CDGM H-K9L) Yakanakisa Form Spherical lenses ayo akagadzirirwa kudzikisa kutenderera aberration achiri kushandisa spherical nzvimbo kugadzira lenzi.Iwo anowanzo shandiswa paasingagumi conjugates mune yakakwirira-simba maapplication uko kaviri isiri sarudzo.Malenzi anowanikwa angave asina kuvharwa kana antireflection (AR) machira akaiswa pamativi ese maviri kuti aderedze mwenje unoratidzwa kubva kune imwe neimwe nzvimbo yelenzi kuderedza kuwanda kwechiedza chinoratidzwa kubva kune imwe neimwe nzvimbo yelens.Aya maAR coatings akagadziridzwa kune spectral renji ye350 - 700 nm (VIS), 650 - 1050 nm (NIR), 1050 - 1700 nm (IR).Uku kupfekedza kunoderedza zvakanyanya kutaridzika kwepamusoro kweiyo substrate isingasviki 0.5% pese pese, ichipa avhareji yekutapurirana mukati mese AR coating renji.Tarisai maGrafu anotevera kune mareferensi ako.
