Lantiy optik yo se eleman optik transparan ak sifas koube ki ka refrakte ak konsantre limyè. Yo lajman itilize nan divès sistèm optik pou manipile reyon limyè, korije vizyon, agrandi objè, ak fòme imaj. Lantiy yo se eleman enpòtan nan kamera, teleskòp, mikwoskòp, linèt, pwojektè, ak anpil lòt aparèy optik.
Gen de kalite prensipal lantiy:
Lantiy konvèks (oswa konvèjans).: Lantiy sa yo pi epè nan sant la pase nan bor yo, epi yo konvèje reyon limyè paralèl ki pase atravè yo nan yon pwen fokal sou bò opoze a nan lantiy la. Lantiy konvèks yo souvan itilize nan loup, kamera, ak linèt pou korije iranjòm.
Lantiy konkav (oswa divèjan).: Lantiy sa yo pi mens nan sant la pase nan bor yo, epi yo lakòz reyon limyè paralèl ki pase nan yo diverge kòm si yo soti nan yon pwen fokal vityèl sou menm bò a nan lantiy la. Lantiy konkav yo souvan itilize nan korije myop.
Lantiy yo fèt baze sou longè fokal yo, ki se distans ki soti nan lantiy la ak pwen fokal la. Longè fokal la detèmine degre koube limyè ak fòmasyon imaj ki kapab lakòz.
Gen kèk tèm kle ki gen rapò ak lantiy optik yo enkli:
Pwen Fokal: Pwen kote reyon limyè konvèje oswa parèt diverge apre yo fin pase nan yon lantiy. Pou yon lantiy konvèks, li se pwen kote reyon paralèl konvèje. Pou yon lantiy konkav, li se pwen kote reyon divergent yo parèt soti.
Longè Fokal: Distans ki genyen ant lantiy la ak pwen fokal la. Li se yon paramèt enpòtan ki defini pouvwa lantiy la ak gwosè imaj la fòme.
Ouverture: Dyamèt lantiy la ki pèmèt limyè pase. Yon ouvèti pi gwo pèmèt plis limyè pase, sa ki lakòz yon imaj pi klere.
Aks optik: Liy santral ki pase nan sant lantiy la pèpandikilè ak sifas li yo.
Pouvwa lantiy: Mezire nan dioptri (D), pouvwa lantiy la endike kapasite refraktif lantiy la. Lantiy konvèks gen pouvwa pozitif, pandan y ap lantiy konkav gen pouvwa negatif.
Lantiy optik te revolusyone divès domèn, soti nan astwonomi rive nan syans medikal, lè yo pèmèt nou obsève objè byen lwen, korije pwoblèm vizyon, epi fè D ak mezi presi. Yo kontinye jwe yon wòl enpòtan anpil nan avanse teknoloji ak eksplorasyon syantifik.
