    Halbeegyada Farsamada

    Calcium Fluoride waxay leedahay codsi ballaaran oo loo yaqaan 'IR' oo ah daaqadaha CaF2, spectrum CaF2 iyo lenses CaF2. Gaar ahaan fasalada saafiga ah ee Kaalshiyamka Fluoride (CaF2) waxay ka helaan codsi waxtar leh UV iyo daaqadaha leysarka UV Excimer. Kaalshiyamka Fluoride (CaF2) ayaa la heli karaa iyada oo lagu duubay Europium iyada oo loo yaqaan 'gamma-ray scintillator' waana ka adag tahay Barium Fluoride.
    Calcium Fluoride waxaa loo isticmaali karaa codsiyo badan, oo ay kujiraan vacuum ultra violet, violet ultra iyo imaraatka kuleylka infrared. Calcium fluoride waxaa dhaqan ahaan loo adeegsadaa naqshadeynta 'apochromatic design' si loo yareeyo faafitaanka iftiinka ee muraayadaha indhaha, labadaba kaamirooyinka iyo teleskoobyada, wuxuuna adeegsadaa warshadaha saliidda iyo gaaska oo ah qayb ka mid ah qalabka wax lagu baaro iyo kuwa muraayadaha indhaha lagu daawado. Ugu horreyntii waxaa loo adeegsaday daaqadaha muraayadaha indhaha, iyo sidoo kale sawirka kuleylka iyo nidaamyada kale ee looga baahan yahay gudbinta sare inta udhaxeysa 0.2m iyo 8µm, kalsiyum fluoride waxaa weerara wax yar oo reagent ah waxayna bixisaa isugeyn hooseeya iyo waxyeello aad u sareysa, oo faa'iido u leh isticmaalkeeda nidaamyada laser.
    Kaalshiyamka Fluoride-ka waxaa loo isticmaalaa nidaamyada muraajicir ee loogu talagalay hagidda dogogga iyo diiradda. Muraayadaha 'CaF2 lenses' iyo daaqadaha ayaa bixiya in ka badan 90% gudbinta laga bilaabo 350nm ilaa 7µm waxaana loo isticmaalaa nidaamyada spectrometer-ka halkaasoo looga baahan yahay baaxad ballac ballaadhan. Calcium Fluoride-ka hooseeya ee soo-celinta ayaa u oggolaanaya Calcium Fluoride in loo isticmaalo nidaamyada iyada oo aan la isticmaalin daboolka ka-hortagga, si ka duwan qalabka kale ee IR.
