Zinc Selenide (ZnSe)
Zinc Selenide ndi chinthu chachikasu chopepuka, cholimba chomwe chimakhala ndi zinc ndi selenium. Zimapangidwa ndi kaphatikizidwe ka zinc vapor ndi H2Se gasi, kupanga ngati mapepala pa gawo lapansi la graphite. ZnSe ili ndi index of refraction ya 2.403 pa 10.6 µm, chifukwa cha mawonekedwe ake abwino kwambiri amajambula, kutsika kocheperako komanso kukana kwambiri ndi kugwedezeka kwamafuta, imagwiritsidwa ntchito kwambiri pamakina owoneka bwino omwe amaphatikiza CO.2laser (yogwira ntchito pa 10.6 μm) yokhala ndi ma laser otsika mtengo a HeNe. Komabe, ndi yofewa ndipo imakanda mosavuta. Kutumiza kwake kwa 0.6-16 µm kumapangitsa kukhala koyenera kwa zida za IR (mazenera ndi magalasi) ndi ma prisms owoneka bwino a ATR, omwe amagwiritsidwa ntchito kwambiri pamakina oyerekeza amafuta. ZnSe imatumizanso kuwala kwina kowoneka ndipo imakhala ndi mayamwidwe otsika mu gawo lofiira la mawonekedwe owoneka bwino, mosiyana ndi germanium ndi silicon, potero imalola kuwongolera kowoneka bwino.
Zinc Selenide imatulutsa oxidize kwambiri pa 300 ℃, imawonetsa kupunduka kwa pulasitiki pafupifupi 500 ℃ ndikulekanitsa pafupifupi 700 ℃. Pachitetezo, mazenera a ZnSe sayenera kugwiritsidwa ntchito pamwamba pa 250 ℃ mumlengalenga wabwinobwino.

Mulingo Wabwino Wotumizira | Mapulogalamu abwino |
0.6 - 16 μm 8-12 μm AR zokutira zilipo Zowonekera mu mawonekedwe owonekera | CO2lasers ndi thermometry ndi spectroscopy, magalasi, mawindo, ndi machitidwe a FLIR Kuwongolera kowoneka bwino |
Chithunzi
Grafu yolondola ndi yokhotakhota ya 10 mm yokhuthala, gawo laling'ono la ZnSe
Malangizo: Pogwira ntchito ndi Zinc Selenide, munthu ayenera kuvala magolovesi nthawi zonse, izi ndichifukwa choti zinthuzo ndizowopsa. Kuti mukhale otetezeka, chonde tsatirani njira zonse zoyenera zodzitetezera, kuphatikiza kuvala magolovesi pogwira zinthuzi komanso kusamba m'manja bwino mukamaliza.
Kuti mudziwe zambiri zatsatanetsatane, chonde onani makina athu owonera kuti muwone kusankha kwathu kwathunthu kopangidwa kuchokera ku zinc selenide.
