N-BK7 (CDGM H-K9L)
Magalasi a Bi-Convex

Mbali zonse ziwiri za Bi-Convex kapena Double-Convex (DCX) Magalasi Ozungulira ndi ozungulira ndipo ali ndi utali wopindika womwewo, ndiwotchuka pamagwiritsidwe ambiri oyerekeza.Ma lens a Bi-convex ndi abwino kwambiri pomwe chinthu ndi chithunzicho zili mbali zotsutsana za disolo ndipo chiŵerengero cha chinthu ndi mtunda wa chithunzi (chiwerengero cha conjugate) chili pakati pa 5: 1 ndi 1: 5 pofuna kuchepetsa kusokonezeka.Kunja kwamtunduwu, magalasi a plano-convex nthawi zambiri amakonda.

N-BK7 ndi galasi lowoneka bwino la borosilicate lomwe limagwiritsidwa ntchito kwambiri powonekera ndi mawonekedwe a NIR, limasankhidwa nthawi iliyonse pomwe mapindu owonjezera a UV wosakanikirana silika (ie, kufalikira kwabwino kupitilira mu UV ndi kutsika kwapang'onopang'ono kwa kukula kwamafuta) sikofunikira.Sitimasintha kugwiritsa ntchito zinthu zaku China zofanana ndi CDGM H-K9L m'malo mwa N-BK7.

Paralight Optics imapereka magalasi a N-BK7 (CDGM H-K9L) Bi-Convex okhala ndi zosankha za zokutira zosatsekedwa kapena antireflection (AR), zomwe zimachepetsa kuchuluka kwa kuwala komwe kumawonekera kuchokera pamwamba pa disolo lililonse.Popeza pafupifupi 4% ya kuwala kwa zochitika kumawonekera pamtunda uliwonse wa gawo lapansi losatsekedwa, kugwiritsa ntchito zokutira zathu zamitundu yambiri za AR kumathandizira kufalikira, komwe kuli kofunikira pakuwunikira kocheperako, ndikuletsa zotsatira zoyipa (mwachitsanzo, zithunzi zamzukwa) zogwirizana ndi zowonetsera zambiri.Kukhala ndi ma optics okhala ndi zokutira za AR zokongoletsedwa pazowoneka bwino za 350 - 700 nm, 650 - 1050 nm, 1050 - 1700 nm zoyikidwa pamalo onse awiri.Kupaka uku kumachepetsa kuwunikira kwakukulu kwa gawo lapansi kuchepera 0.5% pamtunda uliwonse, kumapereka kufalikira kwapakati pamitundu yonse ya AR yopaka ma angles of incidence (AOL) pakati pa 0 ° ndi 30 ° (0.5 NA), Kwa optics omwe amafunidwa. kuti igwiritsidwe ntchito pamakona akuluakulu, ganizirani kugwiritsa ntchito zokutira zokongoletsedwa pakona ya 45°;❖ kuyanika kwa mwambowu ndi kothandiza kuyambira 25 ° mpaka 52 °.Zovala za Broadband zimakhala ndi mayamwidwe wamba a 0.25%.Yang'anani m'ma Grafu otsatirawa kuti mupeze zolozera zanu.
