DRK6617 Prism Refractometer

Qalabkan waxaa loo isticmaali karaa in si dhakhso ah oo sax ah loo go'aamiyo index refractive, celceliska kala firidhsan iyo qayb firidhsan ee walxaha adag iyo dareeraha hufan ama translucent (taas oo ah, waxa ay cabbiri kartaa 706.5nm, 656.3nm, 589.3nm, 546.1nm, 486.1nm, 435. nm, 434.1 Tusmada refractive ee siddeed mawjadaha dhaadheer ee caadiga ah sida nm iyo 404.7nm).

Marka darajada muraayadda indhaha la ogaado, tusmihiisa refractive si degdeg ah ayaa loo cabbiri karaa. Xogtaasi aad bay faa'iido ugu leedahay naqshadaynta iyo samaynta aaladaha indhaha.
Guud ahaan, qalabku waxa uu u baahan yahay in uu lahaado cabbir cayiman marka la cabbirayo index refractive ee muunadda, waxa aanu qalabkani heli karaa index refractive muunada ugu yar isaga oo si sax ah u diyaariya habka immersion, taas oo si gaar ah muhiim u ah ilaalinta saamiga la tijaabiyey.
Maadaama qalabkani uu ku salaysan yahay mabda'a sharciga dib-u-soo-celinta, index refractive ee muunadda la tijaabiyay kuma xaddidna index refractive ee prism ee qalabka. Tani waxay si gaar ah faa'iido u leedahay wax soo saarka tijaabada ah ee alaabta cusub ee warshadaha muraayadaha indhaha.
Sababtoo ah saxnaanta cabbirka qalabku waa 5 × 10-5, isbeddelka index refractive ee walxaha ka dib daaweynta kulaylka sare ee heerkulka waa la qiyaasi karaa.
Iyada oo ku saleysan qodobada kor ku xusan, qalabkani waa mid ka mid ah qalabka lagama maarmaanka u ah warshadaha muraayadaha indhaha, warshadaha qalabka indhaha iyo qaybaha kale ee cilmi-baarista sayniska iyo jaamacadaha.
