Ny lantihy optika dia singa optika mangarahara miaraka amin'ny velarana miolikolika izay afaka manilika sy mampifantoka ny hazavana. Izy ireo dia ampiasaina betsaka amin'ny rafitra optika isan-karazany mba hanodinana taratra hazavana, hanitsiana ny fahitana, hanalefaka zavatra ary hamorona sary. Ny lantihy dia singa manan-danja amin'ny fakan-tsary, teleskaopy, mikraoskaopy, solomaso, projectors, ary fitaovana optika maro hafa.
Misy karazany roa lehibe ny lenses:
Lens convex (na converging).: Matevina kokoa noho ny eo amin'ny sisiny ireo family ireo, ary mampitambatra taratra hazavana mifanindran-dalana izay mandalo azy ireo ka mankamin'ny teboka mifanandrify amin'ilay family. Ny lens convex dia matetika ampiasaina amin'ny solomaso fanamafisam-peo, fakantsary, ary solomaso hanitsiana ny fahitana lavitra.
Lens concave (na diverging).: Manify kokoa ny afovoany noho ny an'ny sisiny ireo family ireo, ary mahatonga ireo tara-pahazavana mifanitsy mandalo amin'izy ireo hisaraka toy ny hoe avy amin'ny teboka virtoaly eo amin'ny lafiny iray amin'ilay family izy ireo. Ny lens concave dia matetika ampiasaina amin'ny fanitsiana ny fahitana akaiky.
Ny lens dia natao mifototra amin'ny halavan'ny focal, izany hoe ny halaviran'ny family mankany amin'ny teboka. Ny halavan'ny focal dia mamaritra ny haavon'ny fiondrika hazavana sy ny fiforonan'ny sary.
Ny teny manan-danja sasany mifandraika amin'ny lantihy optika dia ahitana:
Focal point: Toetran'ny taratra mivondrona na miseho misaraka rehefa avy mandalo amin'ny family. Ho an'ny family convex, dia io no toerana itambaran'ny taratra mifanitsy. Ho an'ny family concave, io no toerana niavian'ny taratra samihafa.
Focal length: Ny elanelana misy eo amin'ny family sy ny focal point. Izy io dia mari-pamantarana manan-danja izay mamaritra ny herin'ny family sy ny haben'ny sary miforona.
nisara-: Ny savaivony amin'ny family mamela ny hazavana mandalo. Ny aperture lehibe kokoa dia mamela hazavana bebe kokoa mandalo, ka miteraka sary mamiratra kokoa.
Optical axisa
Herin'ny Lens: Refesina amin'ny dioptera (D), ny herin'ny family dia manondro ny fahaiza-manaon'ny family. Ny lens convex dia manana hery tsara, fa ny concave kosa manana hery ratsy.
Nanova sehatra isan-karazany ny lantihy optika, manomboka amin'ny astronomia ka hatramin'ny siansa ara-pitsaboana, amin'ny alalan'ny famelana antsika hijery zavatra lavitra, hanitsy ny olan'ny fahitana, ary hanao sary sy fandrefesana marina. Mbola mitana anjara toerana lehibe amin'ny fampivoarana ny teknolojia sy ny fikarohana siantifika izy ireo.
