Nā kānana hoʻopilikia i ka hele pōkole

ʻO ke kānana hele hawewe pōkole, ʻo ia hoʻi, i loko o kahi kikoʻī o ka hawewe lōʻihi, e hoʻouna ʻia ka ʻaoʻao hawewe pōkole, ʻoiai ua ʻoki ʻia ke ala hawewe lōʻihi, ʻo ia ka mea e hoʻokaʻawale i ka nalu lōʻihi a hala i ka nalu pōkole.Ke hoʻohālikelike ʻia me ka kānana aniani optical kala maʻamau, ʻo ka kānana pōkole pōkole i hana ʻia a hoʻomohala ʻia e Bodian he mau mea maikaʻi o ka bandwidth ʻoki ākea ākea, hohonu ʻoki hohonu, kiʻekiʻe hoʻololi steepness, kiʻekiʻe transmittance, high pass rate, a me ka mea kiʻekiʻe. A hiki i ka 95%, hohonu ʻokiʻoki kiʻekiʻe, a hiki i OD4, a me ka laulā ākea spectral cutoff.ʻAʻole mākou e hāʻawi wale i kahi helu nui o nā huahana kānana maʻamau i ka waihona, akā hiki iā mākou ke hana i nā kānana no kāu mau pono.
