N-BK7 (CDGM H-K9L)
Plano-Convex Lenses

Paralight Optics muaj N-BK7 (CDGM H-K9L) Plano-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 reflected los ntawm txhua qhov chaw ntawm lub lens. Txij li thaum kwv yees li 4% ntawm qhov teeb meem teeb pom kev tshwm sim ntawm txhua qhov chaw ntawm lub substrate uas tsis muaj coated, daim ntawv thov ntawm peb cov txheej txheej AR ntau 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, cov duab dab). txuam nrog ntau qhov kev xav. Muaj optics nrog AR txheej optimized rau spectral ntau ntawm 350 - 700 nm, 400 - 1100 nm, 650 - 1050 nm, 1050 - 1700 nm, 1650 - 2100 nm tso rau ntawm ob qhov chaw. Cov txheej no zoo heev txo qhov nruab nrab qhov cuam tshuam ntawm cov substrate tsawg dua 0.5% (Ravg <1.0% rau thaj tsam ntawm 0.4 - 1.1 μm thiab 1.65 - 2.1 μm) rau ib qhov chaw, yielding qhov nruab nrab kis tau zoo thoob plaws AR txheej ntau rau cov ces kaum. Qhov tshwm sim (AOI) ntawm 0 ° thiab 30 ° (0.5 NA). Rau optics npaj los siv rau ntawm qhov xwm txheej loj, xav txog kev siv cov txheej txheem kev kho kom 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.
