Depolarizing
Nā mea hoʻoheheʻe pāpaʻi
ʻOiai ua hoʻolālā ʻia nā beamsplitters non-polarizing e hoʻololi i nā mokuʻāina polarization S a me P o ke kukui e hiki mai ana, ua paʻa mau lākou i ke kukui polarized, ʻo ia hoʻi, e mau ana kekahi mau hopena polarization inā hāʻawi ʻia nā beamsplitters non-polarizing i ke kukui hoʻokomo polarized. .ʻAʻole naʻe ko mākou depolarizing beamsplitters i ka polarization o ka mea i hana ʻia, ka ʻokoʻa o ka noʻonoʻo a me ka lawe ʻana no S- a me P-pol.ʻoi aku ka liʻiliʻi ma lalo o 5%, a i ʻole ʻaʻohe ʻokoʻa i ka noʻonoʻo ʻana a me ka hoʻouna ʻana no S- a me P-pol ma kekahi mau hawewe hoʻolālā.E ʻoluʻolu e nānā i nā pakuhi ma lalo no kāu mau kuhikuhi.
Hāʻawi ʻo Paralight Optics i kahi ākea o nā beamsplitters optical.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 i mea e hōʻemi ai i nā hopena ʻuhane a me nā hopena hoʻopilikia.Loaʻa kā mākou cube beamsplitters i nā hiʻohiʻona polarizing a i ʻole polarizing.Hāʻawi nā Pellicle beamsplitters i nā waiwai hoʻoili nalu mua i ka wā e hoʻopau ana i ka offset beam a me ka ʻuhane.Hōʻike nā beamsplitter dichroic i nā waiwai hoʻoheheʻe ʻia e pili ana i ka lōʻihi hawewe.Pono lākou no ka hoʻohui / ʻoki ʻana i nā kukui laser o nā kala like ʻole.
