Isha ilayska badan ee band waa nidaam indho-indhayn ah oo u qaybiya iftiinka cad ee ka soo baxaya isha iftiinku oo u kala qaybiya qaybo kala duwan hal ama laba qaybood oo kala duwan oo midab leh, ka dibna ka soo baxa hagaha iftiinka.Waxay inta badan ka kooban tahay shan qaybood: isha iftiinka, nidaamka filter, nidaamka wax soo saarka, nidaamka soo bandhigida xakamaynta, iyo armaajooyinka.(Ka eeg sawirka 1 ee qaabka).Waxaa ka mid ah, isha iftiinka, nidaamka shaandhada, iyo nidaamka wax soo saarku waa qaybaha asaasiga ah ee isha iftiinka badan, kaas oo go'aaminaya waxqabadka isha iftiinka.Isha iftiinka guud ahaan waxay qabataa nalka xenon, iftiinka indium ama nalalka kale ee birta ah ee leh waxtarka iftiinka sare leh.Nidaamka shaandhada inta badan waxa loola jeedaa shaandhada midabka, waxa jira filtarrada midabka caadiga ah ee dahaarka leh ama filtarrada midabka band-pass oo tayo sare leh.Waxqabadka kan dambe aad ayuu uga fiican yahay kii hore, kaas oo inta badan hoos u dhigaya xajmiga gooynta ee iftiinka midabka leh, taas oo ah, monochromaticity ee iftiinka midabka ayaa si weyn u wanaajiyay.Daboolida hirarka dhererka caadiga ah ee wax soo saarka waa 350 ~ 1000nm, oo ay ku jiraan inta badan khadadka muuqaalka ee ultraviolet-dheer, iftiinka muuqda iyo gobollada u dhow-infrared.
1. Fluorescence iyo ilo iftiin badan
Marka electrons-ka ka baxsan nukliyeerka ay ku faraxsan yihiin oo ay u boodaan heerka xiisaha leh, elektaroonnada ku jira gobolka xiisaha ayaa ah kuwo aan degganeyn oo mar walba dib ugu boodbooda gobolka dhulka iyaga oo tamar hoose leh.Inta lagu jiro boodboodka, tamarta la helay ayaa lagu sii dayn doonaa qaabka sawir-qaadista..Dhacdada ah in walaxda ay ku raaxaysato xaalad xamaasad leh ka dib markii lagu shiday photon ah hirar dhererkeedu cayiman yahay, ka dibna dib ugu soo boodo heerka tamar hoose iyada oo sii deynaysa sawir-qaade kale oo dherer gaar ah.
Waxaa loo yaqaan 'photoluminescence phenomenon', iyo noloshii photon-ka ee inta badan la sii daayo waxay ka yar tahay 0.000001 ilbiriqsi, taas oo loo yaqaan 'fluorescence';inta u dhaxaysa 0.0001 iyo 0.1 ilbiriqsi, waxa loo yaqaan phosphorescence.Haddii walaxdu is kiciso oo ay soo saarto fluorescence iyada oo aan lahayn kicin iftiin dibadda ah, waxaa la sheegaa in walaxdu leedahay fluorescence gudaha ah.Xaalad kale oo ka mid ah fluorescence waa in la dhaliyo mowjado iftiin leh oo leh hirar kala duwan oo ka soo jeeda hirarka iftiinka asalka ah (sida caadiga ah kicinta gaaban si ay u abuuraan hirar dhaadheer) oo hoos yimaada kicinta iftiinka iftiinka dibadda, iyo muujinta macroscopic waa in la sii daayo iftiin midab kale.Isha iftiinka-band-yada badan ma bixin karto oo kaliya isha iftiinka rogaal celiska ah si loo eego fluorescence gudaha, laakiin sidoo kale isha iftiinka kicinta.
2. Mabda'a kala-soocidda midabka
Mabda'a kala-soocidda midabku waa shardi u ah xulashada saxda ah ee mawjada dhererka (iftiin midabka) iyo midabka midabka isha iftiinka badan ee band.macnaheedu waa adiga oo dooranaya hadhka.
