Muaju LiF (Lithium Flouride) qhia tau hais tias yav tom ntej transmittance hauv VUV thaj av ntawd. Nws siv lub tsev, xwm fab xwm meem thiab lo ntsiab muag pom thiab infrared hauv 0.104 μm - 7 μm. LiF crystalis rhiab rau thermal poob siab thiab yuav tau rov los atmospheric ya raws ntawm 400° C. Tsis tas li irradiation ua xim chaw zov me nyuam. Tus ya raws thiab siab zog tawg puas yuav tsum tau muab ceev faj txaj muag. Besides LiF yog softens ntawm 600° C thiab yog cov yas me ntsis uas yuav tsum bent rau daim hlau voos kheej-kheej. Cov khoom yuav cleaved raws tus (100) thiab tsawg feem ntau (110). Txawm tias tus yam ntxwv kho qhov muag yog zoo tus qauv tsis zoo meej thiab cleavage yog yooj yim. Zoo LiF no feem ntau yog noob los hloov tus txheej txheem Bridgman.

Lithium Flouride qhia tau hais tias kho qhov muag properites. Nws yuav siv tau rau lub tsev, xwm fab xwm meem thiab lo ntsiab muag nqus UV, visibel hab infrared. Vim yog cov paricular lattice qauv, LiF, kuj siv tau ua hluav taws xob xoo diffraction pab kiag li lawm.
Nta:

  1. Mob kis los ntawm 110nm los 7μm;

  2. Optically isotropic, nruab nrab nyuab;

  3. Hygroscopic, unsolvable nyob hauv cov dej;

  4. Rhiab rau thermal poob siab, Cleaved raws tus (100);
