Umehluko phakathi kwe-convex lens kanye ne-concave lens

Ayini amalensi?

Amalensi ayizinto ezibonisa ngale eziklanyelwe ukuhlehlisa ukukhanya ukuze kulungiswe ukubona noma ukukhulisa isithombe. kwento.

Tipos de lentes

Kunezinhlobo ezimbili eziyinhloko zamalensi: amalensi aconvex namalensi aconcave.

Lente convexa

Ilensi eyi-convex ilensi egobile enendawo yangaphandle egobile kanye nendawo engaphakathi egobile. Le lensi iyakwazi ukugxilisa imisebe yokukhanya edlula kuyo iye endaweni eyodwa ebizwa ngokuthi i-focal point.

i-concave lens

Ngakolunye uhlangothi, ilensi eyi-concave ilensi egobile enendawo yangaphandle egobile kanye nendawo yangaphakathi eyisicaba noma ethe ukugoba. Le lens iyakwazi ukuphambukisa imisebe yokukhanya edlula kuyo, okusho ukuthi Imisebe ihlukaniswa njengoba idlula ku-lens.

Ukusetshenziswa kwama-lens

Lente convexa

Amalensi e-Concave anezinhlobonhlobo zokusetshenziswa. Ezinye izibonelo faka:

• Ukulungiswa kombono: Amalensi ayi-convex asetshenziswa ezingilazini nasemalensini ukuze kulungiswe izinkinga zokubona, njengokubona eduze nokubona kude.
• Amalensi akhulisayo: Ama-convex lens nawo asetshenziswa ekukhuliseni izibuko nezibonakude ukuze kukhuliswe isithombe sezinto ezincane.
  
  

i-concave lens

Amalensi e-Concave nawo anezinhlobonhlobo zokusetshenziswa. Ezinye zazo zibalwe ngezansi:

• Ukulungiswa kombono: Amalensi ayi-Concave asetshenziselwa ukulungisa izinkinga ezithile zokubona, njengokubona eduze nokubona kude.
• Izibuko ze-Concave: Izibuko ze-Concave zisetshenziswa kuma-telescopes nasekukhiqizeni izindlu zezibani ukuze zigxilise ukukhanya endaweni ethile.
• Amalensi ezithombe: Amalensi e-Concave asetshenziswa kwamanye amakhamera ukuze kulungiswe ukuphuma kwe-chromatic nokulungisa isithombe.
  
  

Isifinyezo

Kafushane, umehluko omkhulu phakathi kwe-convex lens kanye ne-concave lens yindlela ehlehlisa ngayo imisebe yokukhanya edlula kuyo. Amalensi ayi-convex ayakwazi ukugxilisa imisebe yokukhanya endaweni eyodwa, kuyilapho amalensi aqondile ewahlukanisa. Zombili izinhlobo zamalensi zinezinhlobonhlobo zokusetshenziswa futhi zibalulekile ekulungiseni izinkinga zombono, kanye nokukhulisa nokugxilisa izithombe.
