Ls lens-ka la dhammeeyay

Si faahfaafo

Xakamaynta tayada sare leh, UO waxay u diyaarisay halbeeg led-dhamaaday oo dhammeystiran oo dammaanad qaadaya tayada ugu sareysa marxalad kasta oo soosaarka Rx ah. Waxaa ka mid ah tijaabooyinka alaabada adag, daraasadaha ballaaran ee is-waafajinta iyo imtixaannada tayada ee laga soo qaado dufcad kasta oo muraayadaha indhaha ah. Waxaan wax walba ka soo bixinaynaa hal muraayad cad oo muujineysa oo ah muraayadaha adag ee adag, si ay u buuxiyaan shuruudaha kala duwan ee habayn.

Halkii kaliya tayada qurxinta, muraayadaha indhaha ee la dhammeeyay ayaa ka badan tayada gudaha, sida cabirrada saxda ah iyo xasilloon, gaar ahaan lensformanka bilaashka ah. Shaybaarta bilaashka ah waxay u baahan tahay tayo sare oo muraayadaha indhaha ee dhammeystiran oo lagu dhameeyay qalooca salka hoose oo xasilloon / radius / sankaaga / dhumucda. Muraayadaha la dhammeystiriyey ee aan loo dulqaadan karin waxay u horseedi doontaa karti badan oo luqado ah, foosha, oo gujinaya, iyo dib-u-dhigista dib u dhigis, natiijada ka dhalanaysa in ka badan muraayadda la dhammeeyay laftiisa.

Waa maxay cabiraadaha ugu muhiimsan ee la xiriirta muraayadaha indhaha ee dhammaaday?

Kahor intaadan gelin muraayadaha indhaha ee semi-dhammeeya, waa inaan cadeeyaa dhowr xog, sida radius, sag, qalooca dhabta ah, tusmada qalabka, etter, iwm.

Hore / dhabarka hore:Qiimaha saxda ah ee radius ee xasilloon ayaa aad muhiim ugu ah saxnaanta awoodda iyo joogteynta.

Qalooca dhabta ah:Qalooca saxda ah iyo kuwa saxda ah ee saxda ah (ma aha qalooca magacaabista) aad ayey muhiim ugu tahay saxnaanta awoodda iyo joogteynta.

CT / ET:Dhumucda dhumucda iyo qaro weyn ee qafiifka ah ayaa saameyn ku leh tirada wax soo saarka RX

Tusmada:Tusmada saxda ah iyo tusmada qalabka ayaa labaduba muhiim u ah in la helo awood sax ah.
