N-BK7 (CDGM H-K9L)
Qhov zoo tshaj plaws Form Spherical Lenses

Rau cov lo ntsiab muag kheej kheej, qhov ntev focal ntev tuaj yeem txhais tau los ntawm ntau tshaj ib qho kev sib xyaw ua ke ntawm sab xub ntiag thiab sab nraub qaum ntawm curvature. Txhua qhov sib xyaw ua ke ntawm qhov chaw curvatures yuav ua rau muaj qhov sib txawv ntawm qhov aberration los ntawm lub lens. Lub vojvoog ntawm curvature rau txhua qhov chaw ntawm daim ntawv lo ntsiab muag zoo tshaj plaws tau tsim los txo qis qhov sib txawv ntawm qhov sib txawv thiab coma tsim los ntawm lub lens, optimizing nws rau kev siv ntawm infinite conjugates. Cov txheej txheem no ua rau cov lo ntsiab muag no kim dua li cov lo ntsiab muag plano-convex lossis bi-convex lo ntsiab muag, tab sis tseem pheej yig dua li peb cov kab ntawm CNC-polished aspheric lo ntsiab muag lossis achromats.

Txij li thaum lub lo ntsiab muag yog optimized rau qhov tsawg kawg nkaus qhov chaw, lawv muaj peev xwm theoretically ncav cuag diffraction-limited kev ua tau zoo rau me me input beam diameters. Rau qhov ua tau zoo tshaj plaws hauv kev tsom xam cov ntawv thov, tso qhov chaw nrog lub vojvoog luv luv ntawm curvature (ie, qhov ntau steeply curved nto) ntawm qhov sib tsoo.

Paralight Optics muaj N-BK7 (CDGM H-K9L) Qhov Zoo Tshaj Plaws Zoo Tshaj Plaws Zoo Tshaj Plaws uas yog tsim los kom txo qis qhov sib txawv ntawm qhov sib txawv thaum tseem siv cov duab kheej kheej los tsim lub lens. Lawv feem ntau yog siv nyob rau hauv infinite conjugates nyob rau hauv high-power daim ntaub ntawv qhov twg doublets tsis yog ib qho kev xaiv. Cov lo ntsiab muag yog muaj nyob rau hauv uncoated los yog peb antireflection (AR) coatings tso rau ntawm ob qhov chaw kom txo tau cov teeb pom kev zoo los ntawm txhua qhov chaw ntawm lub lens kom txo tau cov teeb pom kev zoo ntawm txhua qhov chaw ntawm lub lens. Cov AR txheej no tau ua kom zoo rau cov spectral ntau ntawm 350 - 700 nm (VIS), 650 - 1050 nm (NIR), 1050 - 1700 nm (IR). Cov txheej no zoo heev txo qhov siab ntawm qhov pom ntawm lub substrate tsawg dua 0.5% ntawm ib qho chaw, ua rau muaj kev sib kis tau zoo thoob plaws tag nrho AR txheej. Tshawb xyuas cov duab hauv qab no rau koj cov ntaub ntawv siv.
