Arotahi Plano-Concave Tuhituhi PDF

Ko nga arotahi whatu he waahanga whatu maramara me nga mata kopikopiko ka taea te huri me te arotahi i te marama. Ka whakamahia nuitia i roto i nga momo punaha whatu ki te raweke i nga hihi marama, te whakatika i te tirohanga matakite, te whakanui i nga mea, me te hanga whakaahua. Ko nga arotahi he mea tino nui i roto i nga kamera, telescopes, microscopes, eyeglasses, projectors, me te maha atu o nga taputapu whatu.

E rua nga momo arotahi matua:

Ko nga arotahi convex (he converging) ranei: He mātotoru ake enei arotahi i waenganui atu i nga tapa, ka honoa nga hihi marama whakarara e haere ana i roto i a ratau ki te waahi arotahi ki tera taha o te arotahi. Ka whakamahia nga arotahi convex i roto i nga mohiti whakanui, nga kamera, me nga mohiti hei whakatika i te tirohanga tawhiti.

Nga arotahi concave (he rereke ranei).: He angiangi ake enei arotahi i waenganui i nga tapa, a ka rerekee nga hihi marama whakarara i roto i a ratau me te mea e puta mai ana i te waahi arotahi mariko i te taha kotahi o te arotahi. He maha nga wa ka whakamahia nga arotahi concave hei whakatika i te tirohanga tata.

I hangaia nga arotahi i runga i te roa o te arotahi, ko te tawhiti mai i te arotahi ki te waahi arotahi. Ko te roa o te arotahi ka whakatau i te tohu o te piko o te marama me te hanga atahanga ka puta.

Ko etahi kupu matua e pa ana ki nga arotahi whatu ko:

Te arotahi: Ko te waahi ka hono nga hihi marama, ka puta ke ranei i muri i te paahitanga i roto i te arotahi. Mo te arotahi porowhita, koinei te waahi e hono ai nga hihi whakarara. Mo te arotahi concave, koinei te waahi i puta mai ai nga hihi rereke.

Roa arotahi: Te tawhiti i waenga i te arotahi me te waahi arotahi. He tawhā tino nui e tohu ana i te kaha o te arotahi me te rahi o te ahua i hangaia.

Aperture: Ko te diameter o te arotahi ka taea te whiti te marama. Ma te kohao nui ka nui ake te marama ki te haere, ka puta he ahua kanapa.

tuaka whatu: Ko te raina pokapū e haere ana i waenganui o te arotahi e tika ana ki ona mata.

Te kaha o te arotahi: Ka inehia i roto i nga diopters (D), ko te kaha o te arotahi e tohu ana i te kaha o te arotahi o te arotahi. He pai nga mana o nga arotahi convex, ko nga arotahi concave he mana kino.

Ko nga arotahi oro kua huri i nga waahi rereke, mai i te arorangi ki te maatauranga rongoa, ma te tuku i a maatau ki te mataki i nga mea tawhiti, te whakatika i nga raru o te tirohanga, me te mahi atahanga me nga inenga. Ka whai waahi nui tonu ratou ki te ahu whakamua i te hangarau me te torotoro putaiao.
