N-BK7 (CDGM H-K9L)
Bi-Convex Lenses
N-BK7 yog borosilicate crown optical iav dav siv nyob rau hauv pom thiab NIR spectrum, nws yog feem ntau xaiv thaum twg cov kev pab cuam ntxiv ntawm UV fused silica (ie, zoo kis mus rau hauv lub UV thiab ib tug qis coefficient ntawm thermal expansion) tsis tsim nyog. Peb lub neej ntawd siv cov khoom sib npaug Suav ntawm CDGM H-K9L los hloov N-BK7.
Paralight Optics muaj N-BK7 (CDGM H-K9L) Bi-Convex lo ntsiab muag nrog cov kev xaiv ntawm ob qho tib si uncoated los yog peb antireflection (AR) txheej, uas txo cov npaum li cas ntawm lub teeb pom los ntawm txhua qhov chaw ntawm lub lens. Txij li thaum kwv yees li 4% ntawm qhov teeb meem teeb pom kev zoo nyob ntawm txhua qhov chaw ntawm lub substrate tsis muaj coated, daim ntawv thov ntawm peb cov txheej txheem ntau txheej AR txheej txhim kho kev sib kis, uas yog ib qho tseem ceeb hauv kev siv lub teeb qis, thiab tiv thaiv cov teeb meem tsis zoo (xws li, dab dluab) txuam nrog ntau qhov kev xav. Muaj optics nrog AR txheej optimized rau spectral ntau ntawm 350 - 700 nm, 650 - 1050 nm, 1050 - 1700 nm tso rau ntawm ob qhov chaw. Cov txheej no zoo heev txo qhov siab ntawm qhov pom ntawm lub substrate tsawg dua 0.5% ntawm ib qho chaw, ua kom muaj kev sib kis tau zoo thoob plaws tag nrho AR txheej rau cov kaum sab xis ntawm qhov xwm txheej (AOL) ntawm 0 ° thiab 30 ° (0.5 NA), Rau optics npaj. siv rau ntawm qhov xwm txheej loj, xav txog kev siv cov txheej txheem kev cai zoo ntawm 45 ° kaum ntawm qhov xwm txheej; Cov txheej txheem kev cai no siv tau los ntawm 25 ° txog 52 °. Broadband coatings muaj ib qho kev nqus ntawm 0.25%. Tshawb xyuas cov duab hauv qab no rau koj cov ntaub ntawv siv.
