Hoʻokaʻawale pinepine ʻia nā beamsplitters e like me kā lākou hana ʻana: cube a i ʻole pā. Hoʻokumu maoli ʻia nā beamsplitters cube me nā prisms kihi ʻākau ʻelua i hoʻopaʻa ʻia ma ka hypotenuse me kahi uhi hoʻohālike i waena. Ua uhi ʻia ka ʻili hypotenuse o hoʻokahi prisma, a ua hoʻopaʻa ʻia nā prisma ʻelua i lilo i ʻano cubic. I mea e pale aku ai i ka hoʻopōʻino ʻana i ka sima, ua ʻōlelo ʻia e hoʻouna ʻia ke kukui i loko o ka prism i uhi ʻia, e hōʻike pinepine ana i kahi hōʻailona kuhikuhi ma ka ʻili honua.
ʻO nā pōmaikaʻi o nā cube beamsplitters he maʻalahi ke kau ʻana, ka lōʻihi o ka uhi ʻike no ka mea aia ma waena o nā ʻaoʻao ʻelua, a ʻaʻohe kiʻi ʻuhane mai ka wā e hoʻi ai nā noʻonoʻo i ke ala o ke kumu. ʻO nā hemahema o ka cube, ʻoi aku ka nui a me ke kaumaha ma mua o nā ʻano beamsplitters ʻē aʻe a ʻaʻole i uhi i ka laulā o ka lōʻihi hawewe e like me ka pellicle a i ʻole ka polka dot beamsplitters. ʻOiai ke hāʻawi nei mākou i nā koho coating like ʻole. Pono e hoʻohana wale ʻia nā ʻāpana beamsplitters cube me nā kaola i hui pū ʻia no ka mea, ʻo ka hoʻohuli ʻana a i ʻole ka hoʻokaʻawale ʻana o nā kaola e hoʻonui i ka maikaʻi o ke kiʻi.
Hāʻawi ʻo Paralight Optics i nā cube beamsplitters i loaʻa nā hiʻohiʻona polarizing a me ka polarizing ʻole. Hoʻomalu pono ʻia nā beamsplitters non-polarizing no ka hoʻololi ʻana i nā mokuʻāina polarization S a me P o ke kukui e hiki mai ana, akā naʻe me nā beamsplitters non-polarizing, i hāʻawi ʻia i ke kukui hoʻokomo polarized, e mau ana kekahi mau hopena polarization. ʻAʻole koʻikoʻi ko mākou depolarizing beamsplitters i ka polarization o ka mea i hana ʻia, ʻo ka ʻokoʻa o ka noʻonoʻo ʻana a me ka hoʻouna ʻana no S- a me P-pol ma lalo o 6%, a i ʻole ʻaʻohe ʻokoʻa i ka noʻonoʻo a me ka lawe ʻana no S- a me P-pol i kekahi mau nalu nalu. E ʻoluʻolu e nānā i nā pakuhi ma lalo no kāu mau kuhikuhi.
