ʻO nā kikoʻī like ʻole o ke aniani optical flat convex kālele lens

ʻO ka wehewehe pōkole:

Hoʻohana ʻia ka lens aniani opika i nā noi like ʻole e hōʻiliʻili, nānā a hoʻokaʻawale i nā kukui a he mau ʻāpana ia o nā ʻōnaehana lens e hana i kahi hana achromatic.

Aia nā Achromatics i ʻelua a ʻekolu mau mea o nā lens like ʻole i hoʻopaʻa ʻia e kaupalena i ka hopena o ka spherical a me ka chromatic aberration.

He aha ka mea hoʻonuiMakani aniani?

ʻO lākou nā lens hoʻonui i hana ʻia i nā aniani aniani, e like me ke aniani ʻōmaʻomaʻo, Optical aniani lens, K9, a pēlā aku.ʻano paʻa ka mea o ke aniani aniani a haʻahaʻa ka helu kino.ʻAʻole maʻalahi ka makahiki i ka hoʻohana lōʻihi a maʻalahi ka maʻalahi o ka mālama ʻana, i ka manawa like, hiki i ka mea hoʻonui aniani ke hoʻomaʻamaʻa ʻoi aku ka maikaʻi o ka uhi ʻana o ka optical, hiki ke hoʻokō i nā hopena kiʻekiʻe, kiʻekiʻe comparative transmittance, anti infrared a ultraviolet, etc.

ʻO ke aniani i hoʻohana mua ʻia no ka hana ʻana i nā lens, ʻo ia nā puʻupuʻu ma ke aniani puka aniani a i ʻole nā ​​hue waina.Ua like ke ʻano me ka "lei aliʻi", kahi i hele mai ai ka inoa o ke aniani lei aliʻi a i ʻole ke aniani pāpale lei.I kēlā manawa, ʻaʻohe kūlike a me ka huʻa ke aniani.Ma waho aʻe o ke aniani lei aliʻi, aia kekahi ʻano aniani flint me ke kiʻekiʻe o ke kepau.Ma kahi o ka makahiki 1790, ua ʻike ʻo Pierre Louis junnard, he Palani, ʻo ka hoʻoulu ʻana i ke kīʻaha aniani hiki ke hana i ke aniani me ke ʻano like ʻole.I ka makahiki 1884, ua hoʻokumu ʻo Ernst Abbe lāua ʻo Otto Schott o Zeiss iā Schott glaswerke Ag ma Jena, Kelemānia, a ua hoʻomohala i nā aniani aniani i loko o kekahi mau makahiki.I waena o lākou, ʻo ka hana ʻana o ke aniani lei aliʻi barium me ka helu refractive kiʻekiʻe kekahi o nā mea nui i hoʻokō ʻia e ka hale hana aniani Schott.

Mahele:

Optical aniani ua hui pu me oxides o kiʻekiʻe-maʻemaʻe silika, boron, sodium, potassium, zinc, kēpau, magnesium, calcium, barium, etc. e like me ka kiko'ī kumu, hehee ai ma kiʻekiʻe wela i loko o ka platinum crucible, hoʻoulu like me kani ultrasonic hawewe. e wehe i nā ʻōhū;A laila e hoʻomaha mālie no ka manawa lōʻihi e pale aku i ke koʻikoʻi o loko o ka poloka aniani.Pono e ana ʻia ka poloka aniani i hoʻomaloʻo ʻia e nā mea hana optical e nānā inā kūpono ka maʻemaʻe, ka ʻike, ka like, ka refractive index a me ka dispersion index i nā kikoʻī.Hoʻomaʻamaʻa ʻia ka poloka aniani kūpono a hana ʻia e hana ai i kahi embryo ʻoʻoleʻa.

Hoʻokaʻawale:

Māhele pū ʻia nā aniani me ka haku mele like ʻole a me nā waiwai optical ma nā kūlana pili ma ke kiʻi abet.ʻO ka abettu o ka hale hana aniani Schott he mau laina pololei a me nā pihi, e hoʻokaʻawale i ka abettu i nā wahi he nui a hoʻokaʻawale i ke aniani optical;Eia kekahi laʻana, aia ke aniani lei aliʻi K5, K7 a me K10 i ka ʻāpana K, a ʻo ke aniani ʻaʻa F2, F4 a me F5 aia ma ka ʻāpana F. ʻO nā hōʻailona ma nā inoa aniani: F kū no ka ʻaʻa, K no ka pāpale kalaunu, B no ka boron, ba no ka barium. , LA no ka lanthanum, n no ke kepau-ole a me P no ka phosphorus.
No ka lens aniani, ʻoi aku ka nui o ke kihi o ka ʻike, ʻoi aku ka nui o ke kiʻi, a ʻoi aku ka hiki ke hoʻokaʻawale i nā kikoʻī o ka mea.ʻO ka neʻe ʻana kokoke i kahi mea hiki ke hoʻonui i ke kihi nānā, akā ua kaupalena ʻia e ka hiki ke nānā pono o ka maka.Ke hoʻohana nei i ke aniani hoʻonui e hoʻokokoke aku ai i ka maka, a kau i ka mea i loko o kona nānā ʻana e hana i kahi kiʻi virtual pololei.
ʻO ka hana o ke aniani hoʻonui ka hoʻonui ʻana i ke kihi o ka ʻike.Ma ka mōʻaukala, ua ʻōlelo ʻia ua noi ʻia ka hoʻohana ʻana i ke aniani hoʻonui e grosstest, he pīhopa o ʻEnelani i ke kenekulia 13.

ʻOi aku ka pale ʻana o ka aniani aniani ma mua o nā lens ʻē aʻe, akā kaumaha kona paona, a ʻoi aku ka kiʻekiʻe o kāna kuhikuhi kuhikuhi: ʻo ka kiʻiʻoniʻoni maʻamau ʻo 1.523, ʻoi aku ka kiʻiʻoniʻoni ultra-thin ma mua o 1.72, a hiki i 2.0.

ʻO ka mea maka nui o ka lens aniani he aniani optical.ʻOi aku ka kiʻekiʻe o kāna helu hoʻohālikelike ma mua o ka lens resin, no laila ma lalo o ke degere like, ʻoi aku ka lahilahi o ka aniani aniani ma mua o ka lens resin.Loaʻa i ka lens aniani ka transmittance māmā maikaʻi a me nā waiwai mechanical a me nā mea kemika, nā ʻōlelo kuhikuhi refractive mau a me nā waiwai kino a me nā waiwai paʻa.Ua kapa ʻia ka lens me ka waihoʻoluʻu ʻole i ka pā keʻokeʻo keʻokeʻo (kiʻi keʻokeʻo), a ʻo ka kiʻiʻoniʻoni ʻulaʻula i ka kiʻiʻoniʻoni i kapa ʻia ʻo croxay lens (kiʻi ʻulaʻula).Hiki i ka lens Croxay ke komo i nā kukuna ultraviolet a hoʻopaʻa iki i ke kukui ikaika.

He ʻoi aku ka maikaʻi o ka ʻili aniani, ʻaʻole maʻalahi ke ʻohi, a he kiʻekiʻe refractive index.ʻO ke kiʻekiʻe o ka ʻōlelo kuhikuhi refractive, ʻoi aku ka lahilahi o ka lens.Akā, palupalu ke aniani a kaumaha loa ka mea.

ʻO wai ka lens i hoʻohana ʻia i ke aniani hoʻonui?

Leni convex
ʻO ke aniani hoʻonui he lens convex i hoʻohana ʻia e hana i kahi mea i ʻoi aku ka nui ma mua o ka mea maoli.Hoʻohana kēia i ka wā e hoʻokomo ʻia ai ka mea ma kahi mamao ma lalo o ka lōʻihi.

He aha ka nui o ke aniani hoʻonui e pono ai iaʻu?

ʻO ka mea maʻamau, ʻoi aku ka maikaʻi o ka mea hoʻonui 2-3X e hāʻawi ana i kahi kahua ʻike nui aʻe no ka nānā ʻana i nā hana e like me ka heluhelu ʻana, aʻo ka pā liʻiliʻi e pili ana i kahi kiʻekiʻe kiʻekiʻe e kūpono i ka nānā ʻana i nā mea liʻiliʻi.
