Nā ʻano a me ka hoʻohana ʻana i nā prisms

ʻO Prism kahi mea ʻike e hoʻohuli i ka mālamalama ma nā kihi kikoʻī e pili ana i kāna hanana a me nā kihi puka.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.Ua kapa ʻia ka huina ma waena o ke kukuna puka a me ke kukuna hanana, ʻo ka huina hoʻokaʻawale, i 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 wedge a i ʻole ka wedge prism ma ke ʻano he 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.

Nā hiʻohiʻona uhi:

ʻO ka maʻamau, hoʻohana ʻia nā kiʻi ʻoniʻoni hoʻonaninani alumini a me ke kālā ma luna o ka ʻili o ka prism reflector 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.

Nā kahua noi: Loaʻa nā Prisms i nā noi nui i nā lako kikohoʻe, ka noiʻi ʻepekema, nā mea hana lapaʻau, a me nā wahi ʻē aʻe.– Nā lako kikohoʻe: nā kāmeʻa, nā kīwī kaapuni pani (CCTV), nā mea hoʻolalelale, nā pahu kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi, nā lens CCD, a me nā mea ʻike maka.- Ka noiʻi ʻepekema: telescopes, microscopes, pae/nānā no ka nānā ʻana i ka manamana lima a i ʻole nā ​​​​ʻike pū;nā mea hoʻololi lā;mea ana o na ano like ole.- Nā mea hana lapaʻau: cystoscopes/gastroscopes a me nā mea lapaʻau laser ʻē aʻe.

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.Hāʻawi mākou i nā prisms pentagon, nā prisms Dove, nā prisms hale, nā prisms kihi-cube, nā prisms kiʻekiʻe kiʻekiʻe kiʻekiʻe UV fused, a me nā prisms wedge kūpono no ka ultraviolet (UV), nā kukui ʻike (VIS), kokoke i ka infrared (NIR) me nā ʻano kikoʻī like ʻole. pae.
Hoʻopili ʻia kēia mau huahana e like me ka alumini / kala / ke kiʻi ʻoniʻoni gula / anti-reflection film / nickel-chromium pale / pale ʻeleʻele.
Hāʻawi ʻo Jiujon i nā lawelawe prism maʻamau i kūpono i kāu mau koi kikoʻī.Hoʻopili kēia i nā hoʻololi i ka nui/parameters/coating preferences etc. E ʻoluʻolu e kelepona iā mākou no nā kikoʻī hou aku.
