Nā ʻano a me ka hoʻohana ʻana i nā prisms

ʻO Prism kahi mea ʻike maka e hoʻohuli i ka mālamalama ma nā kihi kikoʻī e pili ana i kona hanana a puka i waho. Hoʻohana mua ʻia nā prisms i nā ʻōnaehana optical e hoʻololi i ke ala o nā ala māmā, e hana i nā hoʻohuli kiʻi a i ʻole nā ​​deflections, a hiki i nā hana scanning.

ʻO nā prisms i hoʻohana ʻia e hoʻololi i ke ala o nā kukui kukui hiki ke hoʻokaʻawale ʻia i loko o ka prism hoʻomālamalama a me ka prism refracting.

 

Hana ʻia nā prisms noʻonoʻo ma o ka wili ʻana i hoʻokahi a ʻoi aʻe paha o nā mea hoʻonaninani ma kahi ʻāpana aniani me ka hoʻohana ʻana i ke kumu o ka noʻonoʻo kūloko a me ka ʻenehana uhi. Hoʻomaka ka noʻonoʻo ʻana i loko i ka wā e hōʻea ai nā kukuna māmā mai loko mai o ka prisma i ka ʻili ma kahi kihi ʻoi aku ka nui ma mua o ka huina koʻikoʻi no ka noʻonoʻo ʻana i loko, a ʻike ʻia nā kukuna māmā āpau i loko. Inā ʻaʻole hiki ke ʻike ʻia ka nui o ka noʻonoʻo kūloko o ka hanana, pono e waiho ʻia kahi uhi hoʻonaninani metala, e like me ke kālā, aluminika, a i ʻole ke gula, ma luna o ka ʻili e hōʻemi ai i ka nalowale o ka ikehu māmā ma ka ʻili. Eia kekahi, i mea e hoʻonui ai i ka transmittance o ka prism a hōʻemi a hoʻopau paha i ke kukui hele hewa i loko o ka ʻōnaehana, waiho ʻia nā pale anti-reflection i kahi kiko kikoʻī kikoʻī ma ka inlet a me ka puka waho o ka prism.

Nui nā ʻano prisms reflective i nā ʻano like ʻole. ʻO ka mea maʻamau, hiki ke hoʻokaʻawale ʻia i nā prisms maʻalahi (e like me ka prism kihi ʻākau, prism pentagonal, prism Dove), prism hale, prism pyramid, prism compound, etc.

Hoʻokumu ʻia nā prisms refracting ma ke kumu o ka refraction māmā. Aia i loko o ia mau ʻaoʻao refractive ʻelua, a ʻo ka laina i hana ʻia e ka hui ʻana o nā ʻili ʻelua i kapa ʻia ʻo ka lihi refractive. ʻO ka huina ma waena o nā ʻaoʻao hoʻomāliʻi ʻelua ua kapa ʻia ʻo ka huina refraction o ka prisma, i hōʻike ʻia e ka α. ʻO ka huina ma waena o ke kukuna puka a me ka kukuna hanana i kapa ʻia ʻo ka ʻoki hoʻokaʻawale, hōʻike ʻia e δ. No ka prisma i haawiia, he mau waiwai paa ka huina hoololi α a me ka huina hoopa'i n, a hoololi wale ka huina hoololi δ o ka prisma refractive me ka huina hanana I o ka kukuna malamalama. Ke like ke ala opua o ka malamalama me ka prisma refracting, loaʻa ka waiwai liʻiliʻi o ka huina deflection, a ʻo ka ʻōlelo:

Ua kapa ʻia ka prisma opi a i ʻole ka prisma me kahi kihi refraction liʻiliʻi loa. Ma muli o ka liʻiliʻi ʻole o ka huina hoʻohuli ʻana, i ka wā e ʻike ʻia ai ka mālamalama ma ke poʻo a i ʻole a kokoke i ke kū pololei, hiki ke hoʻohālikelike ʻia ka ʻōlelo no ka ʻae ʻana o ka wili e like me: δ = (n-1) α.

ʻO ka maʻamau, hoʻopili ʻia nā kiʻi ʻoniʻoni hoʻonaninani alumini a me ke kālā ma luna o ka ʻili o ka mea hoʻomālamalama prism e hoʻomaikaʻi i ka hoʻomālamalama māmā. Hoʻopili pū ʻia nā kiʻi ʻoniʻoni anti-reflection ma luna o ka hanana a me nā ʻaoʻao puka e hoʻonui i ka hoʻouna ʻana i ka māmā a hōʻemi i ke kukui hele ʻole ma nā ʻano UV, VIS, NIR, a me SWIR.

Hāʻawi ʻo Jiujon Optics i kahi ʻano huahana prism e like me nā prisms ʻākau ʻākau i hana ʻia mai ke aniani H-K9L a i ʻole UV fused quartz.
