Farqiga u dhexeeya lens convex iyo lens concave

Waa maxay lenses?

Lenses waa shay hufan oo loogu talagalay in ay iftiinka iftiinka u saxaan ama u weyneeyaan sawirka. ee shay.

Tipos de lentes

Waxa jira laba nooc oo lenses ah: lenses convex iyo concave lenses.

Lente convexa

Lens-ku-jiidku waa muraayad qalloocan oo leh dusha sare ee bararsan iyo oog gudaha ah oo fidsan. Lenskani waxa uu awood u leeyahay in uu xoojiso fallaadhaha iftiinka ee dhex mara meel keliya oo loo yaqaanno “focal point”.

lenski concave

Dhanka kale, lenska concave waa muraayad qalloocan oo leh dusha sare ee koojka ah iyo korka gudaha ah oo fidsan ama wax yar convex ah. Muraayaddani waxa ay awood u leedahay in ay kala duwo fallaadhaha iftiinka ee dhex mara, taasoo la macno ah in Falaadhadu waa kala go'aan markay dhex maraan muraayadda.

Isticmaalka muraayadaha

Lente convexa

Lenses concave waxay leeyihiin tiro balaadhan oo ah isticmaalka. Tusaalooyin qaar waxaa ka mid ah:

• Sixitaan aragga: lenses convex waxaa loo isticmaalaa muraayadaha iyo muraayadaha indhaha si loo saxo dhibaatooyinka aragga, sida aragga dhow iyo aragtida fog.
• Muraayadaha waaweyn: lenses Convex ayaa sidoo kale loo isticmaalaa muraayadaha waaweynaynta iyo telescopes si loo weyneeyo sawirka walxaha yaryar.
  
  

lenski concave

Lenses concave sidoo kale waxay leeyihiin tiro balaadhan oo ah isticmaalka. Qaar ka mid ah ayaa hoos ku taxan:

• Sixitaan aragga: lenses concave waxa loo isticmaalaa in lagu saxo qaar ka mid ah dhibaatooyinka aragga, sida aragga dhow iyo aragti fog.
• Muraayadaha Concave: Muraayadaha concave waxaa loo isticmaalaa telescopes iyo samaynta guryaha laydhka si ay iftiinka ugu ururiyaan jiho gaar ah.
• Muraayadaha sawirada: muraayadaha concave ayaa loo isticmaalaa kamaradaha qaarkood si loo saxo aberration chromatic iyo si loo saxo sawirka.
  
  

Soo Koobid

Marka la soo koobo, farqiga ugu weyn ee u dhexeeya lenska convex iyo lenska concave waa sida ay u celiyaan fallaadhaha iftiinka ee dhex mara. Lenses convex waxay awoodaan inay diirada saaraan fallaadhaha iftiinka hal dhibic, halka muraayadaha concave ay kala soocaan. Labada nooc ee lenses waxay leeyihiin adeegsiyaal kala duwan waxayna lagama maarmaan u yihiin hagaajinta dhibaatooyinka aragga, iyo sidoo kale weyneynta iyo diiradda saarida sawirada.
