I-N-BK7 (CDGM H-K9L)
I-Bi-Convex Lens
I-N-BK7 iyingilazi ebonakalayo ye-borosilicate Crown esetshenziswa kakhulu ku-spectrum ebonakalayo kanye ne-NIR, ivame ukukhethwa noma nini lapho izinzuzo ezengeziwe ze-silica ehlanganisiwe ye-UV (okungukuthi, ukudluliswa okuhle ngokuqhubekayo ku-UV kanye ne-coefficient ephansi yokwandisa okushisayo) kungadingeki. Senza ngokuzenzakalelayo ukusebenzisa izinto ezilinganayo zesiShayina ze-CDGM H-K9L ukuze simiselele i-N-BK7.
I-Paralight Optics inikezela ngamalensi e-Bi-Convex e-N-BK7 (CDGM H-K9L) anezinketho zokungamboziwe noma ze-antireflection (AR), okunciphisa inani lokukhanya elibonakala endaweni ngayinye yelensi. Njengoba cishe u-4% wokukhanya kwesigameko uboniswa endaweni ngayinye ye-substrate engagcotshiwe, ukusetshenziswa kwe-AR yethu yezinga eliphezulu yokusebenza kwe-AR kuthuthukisa ukudluliswa, okubalulekile ekusetshenzisweni kokukhanya okuphansi, futhi kuvimbele imiphumela engathandeki (isb. izithombe zezipoki) ezihlotshaniswa nokubonisa okuningi. Ukuba nama-optics anezingubo ze-AR ezilungiselelwe uhla lwe-spectral luka-350 – 700 nm, 650 – 1050 nm, 1050 – 1700 nm olufakwe kuzo zombili izindawo. Lokhu kunamathela kunciphisa kakhulu ukubonakala okuphezulu kwendawo engaphansi engaphansi kuka-0.5% endaweni ngayinye, kunikeze ukudluliswa okumaphakathi okuphezulu kulo lonke uhla lwe-AR lwama-angles of incidence (AOL) phakathi kuka-0° no-30° (0.5 NA), Okokusebenza okuhlosiwe. okufanele isetshenziswe kuma-engeli amakhulu wesigameko, cabanga ukusebenzisa i-coating yangokwezifiso elungiselelwe nge-engeli engu-45° yesigameko; lokhu kunamathela ngokwezifiso kusebenza kusuka ku-25 ° kuya ku-52 °. I-Broadband coatings inokumuncwa okujwayelekile okungu-0.25%. Hlola amagrafu alandelayo ukuze uthole izithenjwa zakho.
