Polarizing ʻole
Nā mea hoʻoheheʻe pāpaʻi

Hana pololei nā Beamsplitters i ko lākou inoa, e hoʻokaʻawale i ke kukui ma kahi ratio i koho ʻia ma nā ʻaoʻao ʻelua.Eia hou, hiki ke hoʻohana ʻia nā beamsplitters i hope e hoʻohui i ʻelua mau kaola like ʻole i hoʻokahi.Hoʻohana mau ʻia nā beamsplitters maʻamau me nā kumu kukui unpolarized e like me ke kūlohelohe a i ʻole polychromatic, hoʻokaʻawale lākou i ke kukui e ka pākēneka o ka ikaika, e like me 50% ka hoʻouna ʻana a me ka 50% noʻonoʻo, a i ʻole 30% ka lawe ʻana a me ka 70% noʻonoʻo.Ua hoʻokaʻawale nā beamsplitters Dichroic i ke kukui e hiki mai ana e ka lōʻihi o ka nalu a hoʻohana mau ʻia i nā noi fluorescence e hoʻokaʻawale i nā ala hoʻohiwahiwa a me nā ala hoʻokuʻu, hāʻawi kēia mau beamsplitters i ka lakene hoʻokaʻawale e hilinaʻi ana i ka lōʻihi o ka nalu o ke kukui hanana a he mea pono no ka hoʻohui ʻana / hoʻokaʻawale i nā kukuna laser o nā ʻano like ʻole. kala kala.

Hoʻokaʻawale pinepine ʻia nā beamsplitters e like me kā lākou hana ʻana: cube a i ʻole pā.ʻO ka pā beamsplitter kahi ʻano maʻamau o ka beamsplitter i haku ʻia me kahi pani aniani lahilahi me kahi uhi ʻike i hoʻopaʻa ʻia no kahi kihi 45° o ka hanana (AOI).Ua hoʻokaʻawale ʻia nā kukui palaki maʻamau ma kahi lākiō i kūʻokoʻa i ka lōʻihi o ka nalu a i ʻole ke kūlana polarization, aʻo ka polarizing plate beamsplitters i hoʻolālā ʻia e mālama i nā mokuʻāina polarization S a me P.

ʻO nā pōmaikaʻi o ka pā beamsplitter he liʻiliʻi ka chromatic aberration, emi ka absorption ma muli o ka liʻiliʻi o ke aniani, ʻoi aku ka liʻiliʻi a me nā hoʻolālā māmā i hoʻohālikelike ʻia me kahi pahu beamsplitter.ʻO nā pōʻino o ka plate beamsplitter nā kiʻi ʻuhane i hana ʻia e ka ʻike ʻia ʻana o ka mālamalama mai nā ʻaoʻao ʻelua o ke aniani, ka neʻe ʻana i ka ʻaoʻao o ke kaola ma muli o ka mānoanoa o ke aniani, paʻakikī ke kau ʻana me ka hoʻololi ʻole ʻana, a me ko lākou naʻau i ke kukui polarized.

Loaʻa i kā mākou papa beamsplitters kahi ili mua i uhi ʻia e hoʻoholo ai i ka lakio hoʻokaʻawale ʻana i ka lākiō ʻoiai ua wili ʻia ka ʻili hope a uhi ʻia ʻo AR.Hoʻolālā ʻia ka Wedged Beamsplitter Plate e hana i nā kope i hoʻopaʻa ʻia he nui o ka beam hoʻokomo hoʻokahi.

No ke kōkua ʻana i ka hōʻemi ʻana i nā hopena hoʻopilikia i makemake ʻole ʻia (e laʻa, nā kiʻi ʻuhane) i hoʻokumu ʻia e ka hui ʻana o ka mālamalama i ʻike ʻia mai ka ʻaoʻao mua a me hope o ka optic, ua loaʻa i kēia mau papa beamsplitters āpau kahi uhi antireflection (AR) i waiho ʻia ma ka ʻili hope.Hoʻolālā ʻia kēia uhi no ka lōʻihi hawewe hana like me ka uhi ʻana i ka beamsplitter ma ka ʻili mua.Ma kahi o 4% o ka hanana māmā ma 45 ° ma kahi substrate uncoated e ʻike ʻia;ma ka hoʻopili ʻana i kahi uhi AR ma ka ʻaoʻao hope o ka beamsplitter, ua hoʻemi ʻia kēia pākēneka i ka awelika o ka liʻiliʻi ma lalo o 0.5% ma ka lōʻihi o ka nalu hoʻolālā o ka uhi.Ma waho aʻe o kēia hiʻohiʻona, he 30 arcmin wedge ka ʻili hope o kā mākou mau mea hoʻoheheʻe pāpaʻi pōʻai, no laila, e ʻokoʻa ka hapa o ka mālamalama e ʻike ʻia mai kēia ʻili AR-coated.
Hāʻawi ʻo Paralight Optics i nā ʻāpana beamsplitters pā i loaʻa i nā hiʻohiʻona polarizing a me ka polarizing ʻole.Hoʻokaʻawale ʻia nā kukui kīwaha non-polarizing maʻamau i ka lākiō i ʻōlelo ʻia i kūʻokoʻa i ka lōʻihi o ka nalu o ka mālamalama a i ʻole ke kūlana polarization, akā ua hoʻolālā ʻia nā polarizing plate beamsplitters e mālama i nā mokuʻāina polarization S a me P.

ʻO kā mākou papa polarizing ʻolenā kukui uilahana ʻia e N-BK7, Fused Silica, Calcium Fluoride a me Zinc Selenide e uhi ana i ka UV a i ka MIR wavelength range.Hāʻawi pū mākoubeamsplitters no ka hoʻohana ʻana me Nd:YAG nā lōʻihi nalu (1064 nm a me 532 nm).No kekahi ʻike e pili ana i nā uhi o nā beamsplitters non-polarizing e N-BK7, e ʻoluʻolu e nānā i nā kiʻi ma lalo mai kāu mau kuhikuhi.

ʻAʻole-Polarizing Plate Beamsplitter

ʻO nā beamsplitters pāpaʻi he pā aniani lahilahi a palahalaha i uhi ʻia ma ka ʻili mua o ka substrate.ʻO ka hapa nui o nā beamsplitters pā e loaʻa i kahi uhi anti-reflection ma ka ʻaoʻao ʻelua e wehe i nā noʻonoʻo Fresnel makemake ʻole.Hoʻolālā pinepine ʻia nā beamsplitters papa no kahi 45° AOI.No nā pani me ka 1.5 index of refraction a me 45° AOI, hiki ke hoʻohālikelike ʻia ka mamao hoʻoneʻe kukuna (d) me ka hoʻohana ʻana i ka hoohalike ma ke kaha kiʻi hema.
