Muraayadaha aspheric waxay leeyihiin joomatariyaal dusha sare oo kakan sababta oo ah ma raacaan qayb ka mid ah goobaha.Muraayadaha Aspheric waa wareeg ahaan isku mid ah waxayna leeyihiin hal ama in ka badan oogada aspheric oo ka duwan qaab ahaan goob.
Faa'iidada ugu weyn ee muraayadaha noocan oo kale ah waa in ay si weyn u yareeyaan aberration spherical.Aberration sppherical waxay dhacdaa marka muraayadu aanay diiradda saari karin dhammaan iftiinka soo socda isla barta saxda ah.Sababtoo ah dabeecadda qaabka dusha aan caadiga ahayn ee aspheric, waxay u oggolaaneysaa hirar badan oo iftiin ah in la maareeyo isku mar, taas oo u oggolaanaysa dhammaan iftiinka in diiradda la saaro isla barta isku midka ah, taasoo keentay sawirro fiiqan.
Dhammaan muraayadaha aspheric, ha ahaadeen kuwo isku dhafan ama isku dhafan, laguma qeexi karo hal radius ee curvature, taas oo qaabkooda lagu qeexay isle'egta Sag, taas oo ah doorsooma, iyo "k" waxay qeexaysaa qaabka guud ee dusha aspheric.
In kasta oo muraayadaha aspheric ay bixiyaan faa'iidooyin qaar ka mid ah muraayadaha caadiga ah, qaabeyntooda gaarka ah ayaa ka dhigaysa mid aad u adag in la soo saaro, sidaas darteed naqshadeeyayaasha indhaha waa in ay miisaamaan faa'iidooyinka waxqabadka qiimaha sare.Nidaamyada casriga ah ee casriga ah ee isticmaala walxaha aspheric ee naqshadahooda waxay yareyn karaan tirada muraayadaha loo baahan yahay, taas oo u oggolaanaysa abuurista nidaamyo fudud, nidaamyo isku dhafan, iyada oo weli la ilaalinayo oo inta badan ka badan waxqabadka nidaamyada iyadoo la adeegsanayo kaliya walxaha wareegsan.Inkasta oo uu ka qaalisan yahay muraayadaha caadiga ah, muraayadaha aspheric waxay noqon karaan beddel soo jiidasho leh iyo ikhtiyaar xoog leh oo loogu talagalay muraayadaha waxqabadka sare leh.
Sagxadaha aspheric waxaa lagu samayn karaa qaabab kala duwan.Dusha sare ee aspheric-ka aasaasiga ah waxaa lagu soo saaray tignoolajiyada qaabaynta duritaanka, taas oo xaqiijin karta noocyo kala duwan oo sagxadaha aspheric ah, inta badan codsiyada xoogga saaraya iftiinka (goobta hillaaca).Aspheres aad u saxan oo kakan waxay u baahan yihiin jiil CNC gaar ah iyo dhalaalid.
Walxaha aspherical-ka, oo ay ku jiraan muraayadaha-semi-optical iyo optical, iyo xitaa walxaha caaga ah sida polycarbonate, polyurethane ama silicone.
