N-BK7 (CDGM H-K9L)
Yakanakisa Form Spherical Lenses

Kune spherical lenzi, yakapihwa kureba yakatarisana inogona kutsanangurwa neinodarika imwe musanganiswa wemberi uye kumashure radii yeku curvature. Kusanganiswa kwega kwega kwepamusoro curvatures kunozokonzera huwandu hwakasiyana hwekukanganisa kunokonzerwa nelens. Iyo radius ye curvature yenzvimbo yega yega yeakanakisa fomu lenses yakagadzirirwa kudzikisira spherical aberration uye coma inogadzirwa nelens, ichikwirisa kuti ishandiswe paasingaperi conjugates. Maitiro aya anoita kuti malenzi aya adhure kupfuura plano-convex kana bi-convex lenzi, asi zvichiri kudhura zvakanyanya pane yedu yekutanga mutsara weCNC-yakakwenenzverwa aspheric lenzi kana achromats.

Sezvo malenzi akagadziridzwa kweudiki saizi yenzvimbo, anogona ne theoretically kusvika diffraction-shoma kuita kwemadhayamita madiki ekupinza. Kuti uite zvakanakisa mukutarisisa maapplications, isa pamusoro neradius ipfupi yekumisikidza (kureva, iyo yakanyanya kukwirisa nzvimbo yakakombama) yakananga kune yakasanganiswa sosi.

Paralight Optics inopa N-BK7 (CDGM H-K9L) Yakanakisa Form Spherical lenses ayo akagadzirirwa kuderedza kutenderera kwemhepo 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 kuti antireflection (AR) machira akaiswa pamativi ese ari 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.
