    Silicon Ko te karaihe mono matua whakamahia i roto i te āhua-kaiwhakahaere me he kore-absorptive i 1.2μm ki 6μm rohe IR.Ka whakamahia i konei hei waahanga whatu mo nga tono rohe IR.
    Ka whakamahia te Silicon hei matapihi whatu i roto i te roopu 3 ki te 5 micron me te taputapu mo te hanga whiriwhiringa whatu.Ko nga poraka nui o Silicon me nga kanohi kua whakakoapahia ano hoki hei whainga neutron i roto i nga whakamatautau Ahupūngao.
    Ka whakatipuhia a Silicon e Czochralski nga tikanga toia (CZ) me etahi o te hāora e puta ai he roopu whakauru ki te 9 microns.Hei karo i tenei, ka taea te whakarite a Silicon ma te mahinga Float-Zone (FZ).Ko te Silicon Optical te nuinga o te waa he ngawari noa (5 ki te 40 ohm cm) mo te tuku pai ake i te 10 microns.Kei a Silicon tetahi roopu whakawhiti atu 30 ki te 100 microns e whai hua ana i roto i nga rawa teitei rawa kore utu.Ko te doping ko Boron (momo-p) me te Phosphorus (momo-n).
    Taupānga:
    • He pai mo te 1.2 ki te 7 μm tono NIR
    • Whanui 3 ki te 12 μm paninga anti-whakaata
    • He pai mo nga tono taumaha
    Āhuahira:
    • Ko enei matapihi silicone karekau e tuku i te rohe 1µm i raro iho ranei, na reira kei nga rohe IR tana tono matua.
    • Na te kaha o te wera o te waiariki, he pai mo te whakamahi hei whakaata laser mana teitei
    ▶ He mata whakarewa kanapa nga matapihi hiona;ka whakaata, ka mimiti engari karekau e tuku ki nga rohe e kitea ana.
    ▶Silicon matapihi mata whakaata hua i roto i te mate tuku o 53%.(raraunga ine 1 whakaata mata i te 27%)
