    Technical Parameters

    Iyo Germanium semono crystal inonyanya kushandiswa mune semi-conductor haina-kunyura pa2μm kusvika 20μm IR matunhu.Inoshandiswa pano sechinhu chemaziso chekushandisa IR dunhu.
    Germanium chinhu chakakwira index chinoshandiswa kugadzira Attenuated Total Reflection (ATR) prisms ye spectroscopy.Yayo refractive index ndeyekuti Germany inogadzira inoshanda yakasikwa 50% beamsplitter pasina kudiwa kwekupotera.Germanium inoshandiswawo zvakanyanya se substrate yekugadzira mafirita emaziso.Germanium inovhara iyo yese 8-14 micron thermal bhendi uye inoshandiswa muma lens masisitimu ekufungidzira kwekupisa.Germanium inogona kuve AR yakashongedzwa neDiamondi ichigadzira yakanyanya kuomarara kumberi optic.
    Germanium inorimwa ichishandisa nzira yeCzochralski nenhamba diki yevagadziri muBelgium, USA, China neRussia.Indekisi yerefractive yeGermanium inoshanduka nekukasira netembiricha uye zvinhu zvinobva zvaita opaque pamasaisai ese ari pamusoro pe350K sezvo gwapa rebhendi richifashama nemaerekitironi anopisa.
    Application:
    • Ideal for near-IR applications
    • Broadband 3 kusvika 12 μm anti-reflection coating
    • Yakanakira zvikumbiro zvinoda kupararira kwakaderera
    • Yakakura kune yakaderera simba CO2 Laser application
    Feature:
    • Aya mahwindo egermanium haafambise pa 1.5µm mudunhu kana pasi, saka kushandiswa kwayo kukuru kuri munzvimbo dzeIR.
    • Mahwindo eGermany anogona kushandiswa mukuedza kwakasiyana-siyana kwe infrared.
