MgF2 Substrate Tsanangudzo
MgF2 substrate inoreva substrate yakagadzirwa ne magnesium fluoride (MgF2) crystal material.MgF2 is inorganic compound inoumbwa ne magnesium (Mg) uye fluorine (F) zvinhu.
MgF2 substrates ine akati wandei anocherekedza zvimiro zvinoita kuti ive yakakurumbira mune akasiyana maapplication, kunyanya muminda ye optics uye yakaonda firimu deposition:
1. Kujeka kwepamusoro: MgF2 ine kujeka kwakanakisisa mu ultraviolet (UV), inooneka uye infrared (IR) nzvimbo dze electromagnetic spectrum.Iyo ine hupamhi hwekutapurirana siyana kubva kune ultraviolet inosvika 115 nm kusvika infrared inosvika 7,500 nm.
2. Low index of refraction: MgF2 ine zvinyorwa zvishoma zvishoma zvekugadzirisa, izvo zvinoita kuti ive chinhu chakanaka cheA AR coatings uye optics, sezvo inoderedza zviratidzo zvisingadiwi uye inovandudza kufambisa kwechiedza.
3. Kunyura kwakaderera: MgF2 inoratidzira kunyura kwakaderera mu ultraviolet uye inooneka spectral nzvimbo.Ichi chivakwa chinoita kuti chishande mumashandisirwo anoda kujeka kwepamusoro, senge lenzi, maprisms, uye windows eultraviolet kana matanda anooneka.
4. Kugadzikana kwemakemikari: MgF2 inogadziriswa nemakemikari, inopesana nemhando dzakasiyana-siyana dzemakemikari, uye inochengetedza maitiro ayo optical uye emuviri pasi pehuwandu hwemamiriro ezvinhu ezvakatipoteredza.
5. Thermal kugadzikana: MgF2 ine nzvimbo yakanyanyisa yakanyunguduka uye inogona kumira kutonhora kwekushanda kwepamusoro pasina kukanganisa kukuru.
MgF2 substrates inowanzo shandiswa mumachira emaziso, matete firimu deposition process, uye optical windows kana lenzi mumidziyo yakasiyana siyana uye masisitimu.Ivo vanogona zvakare kushanda senge buffer akaturikidzana kana matemplate ekukura kwemamwe mafirimu matete, semiconductor zvinhu kana esimbi machira.
Aya ma substrates anowanzo gadzirwa uchishandisa hunyanzvi senge mhute deposition kana yemuviri mhute nzira dzekufambisa, uko MgF2 zvinhu zvinoiswa pane yakakodzera substrate zvinhu kana kukura sekristaro imwechete.Zvichienderana nezvinodiwa zvekushandisa, ma substrates anogona kunge ari muchimiro chewafers, mahwendefa, kana maumbirwo etsika.
