CaF2 Windows
Calcium Fluoride ni ohun elo IR ni ibigbogbo bi awọn window CaF2 spectroscopic, CaF2 prisms ati awọn lẹnsi CaF2.Paapa awọn onipò mimọ ti Calcium Fluoride (CaF2) wa ohun elo to wulo ninu UV ati bi awọn ferese laser UV Excimer.Calcium Fluoride (CaF2) wa ni doped pẹlu Europium bi scintillator gamma-ray ati pe o le ju Barium Fluoride lọ.
Calcium Fluoride le ṣee lo fun ọpọlọpọ awọn ohun elo, pẹlu igbale ultraviolet, ultraviolet ati aworan igbona infurarẹẹdi.Calcium fluoride jẹ lilo aṣa ni apẹrẹ apochromatic lati dinku pipinka ina ni awọn lẹnsi, mejeeji ni awọn kamẹra ati awọn telescopes, ati pe o ni lilo ninu ile-iṣẹ epo ati gaasi bi paati ninu awọn aṣawari ati awọn iwoye.Ti a lo ni akọkọ ni awọn ferese iwoye, ati ni aworan igbona ati awọn ọna ṣiṣe miiran nibiti o ti nilo gbigbe giga laarin 0.2µm ati 8µm, kalisiomu fluoride jẹ ikọlu nipasẹ awọn reagents diẹ ati pe o funni ni iye iwọn gbigba kekere ati ilodisi ibajẹ giga, anfani ni lilo rẹ ni excimer lesa awọn ọna šiše.
Calcium Fluoride jẹ lilo ninu awọn ọna ṣiṣe iwoye fun idari ina ati idojukọ.Awọn lẹnsi CaF2 ati awọn ferese nfunni lori 90% gbigbe lati 350nm si 7µm ati pe wọn lo ninu awọn ọna ẹrọ iwoye nibiti ibiti o ti nilo iwọn gigun gbooro.Atọka kekere ti Calcium Fluoride ti ifasilẹ gba Calcium Fluoride laaye lati ṣee lo ninu awọn ọna ṣiṣe laisi lilo awọn aṣọ atako, ko dabi awọn ohun elo IR miiran.
