Daaqadaha CaF2
Calcium Fluoride waxay leedahay codsi IR baahsan sida daaqadaha CaF2 spectroscopic, CaF2 prisms iyo CaF2 lenses.Gaar ahaan darajooyinka saafiga ah ee Calcium Fluoride (CaF2) waxay ka helaan codsi faa'iido leh UV iyo sida muraayadaha UV Excimer laser.Calcium Fluoride (CaF2) ayaa diyaar ah oo lagu daro Europium sida scintilator gamma-ray waana ka adag tahay Barium Fluoride.
Calcium Fluoride waxaa loo isticmaali karaa codsiyo badan, oo ay ku jiraan vacuum ultraviolet, ultraviolet iyo sawirka kulaylka infrared.Calcium fluoride waxaa dhaqan ahaan loo isticmaalaa naqshadaynta apochromatic si loo yareeyo kala firdhisanaanta iftiinka ee muraayadaha, labadaba kamaradaha iyo telescopes, waxayna u isticmaashaa warshadaha saliidda iyo gaaska sida qayb ka mid ah qalabka wax baara iyo spectrometers.Inta badan loo isticmaalo daaqadaha spectroscopic, iyo sidoo kale sawirada kulaylka iyo nidaamyada kale ee gudbinta sare ee u dhaxaysa 0.2µm iyo 8µm loo baahan yahay, fluoride calcium waxaa soo weeraray reagents yar waxayna bixisaa nuugista hoose iyo heer waxyeello sare leh, faa'iido u leh isticmaalkeeda excimer hababka laysarka.
Calcium Fluoride waxaa loo isticmaalaa hababka spectroscopy si loo hago iftiinka iyo diiradda saarista.Muraayadaha CaF2 iyo daaqadaha waxay bixiyaan in ka badan 90% gudbinta laga bilaabo 350nm ilaa 7µm waxaana loo adeegsadaa nidaamyada spectrometer-ka halkaas oo kala duwanaansho dherer ballaaran looga baahan yahay.Kaalshiyamka Fluoride-ka tusmihiisa hoose ee dib-u-soo-celinta waxay u oggolaanaysaa Kaalshiyam Fluoride in lagu isticmaalo nidaamyada iyada oo aan la isticmaalin dahaarka ka-hortagga, si ka duwan qalabka kale ee IR.
