UV Fused Silica (JGS1)
Bi-Convex Lenses
Peb lub neej ntawd siv cov khoom sib npaug Suav ntawm fused silica, feem ntau muaj peb hom fused silica hauv Suav teb: JGS1, JGS2, JGS3, lawv siv rau ntau daim ntawv thov.Thov xa mus rau cov ntaub ntawv ntxaws ntxaws hauv qab no:
JGS1 feem ntau yog siv rau optics nyob rau hauv lub UV thiab pom wavelength ntau yam.Nws yog dawb ntawm npuas thiab inclusions.Nws yog sib npaug rau Suprasil 1 & 2 thiab Corning 7980.
JGS2 feem ntau yog siv los ua lub substrate ntawm iav los yog reflectors, vim nws muaj cov npuas me me hauv.Nws yog sib npaug rau Homosil 1, 2 & 3.
JGS3 yog pob tshab nyob rau hauv ultraviolet, pom thiab infrared spectral cheeb tsam, tab sis nws muaj ntau npuas nyob rau hauv.Nws yog sib npaug rau Suprasil 300.
Paralight Optics muaj UV lossis IR-Grade Fused Silica (JGS1 lossis JGS3) Bi-Convex Lenses muaj nyob rau hauv ntau qhov sib txawv, tsis yog lo ntsiab muag lossis nrog cov txheej txheem ua haujlwm siab ntau txheej antireflection (AR) txheej optimized rau thaj tsam ntawm 245-400nm, 350-700nm, 650-1050nm, 1050-1700nm 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% ib qhov chaw thoob plaws tag nrho AR txheej ntau rau kaum ntawm qhov xwm txheej (AOI) ntawm 0 ° thiab 30 °.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 °.Tshawb xyuas cov duab hauv qab no rau koj cov ntaub ntawv siv.
