Nā kānana ʻenehana kiʻekiʻe a me nā Polarizers/Waveplates
ʻO kahi kānana he ʻano kūikawā o ka puka aniani palahalaha, i ka wā e kau ʻia ai ma ke ala māmā, e hoʻouna a hōʻole paha i kahi ʻano o nā lōʻihi nalu (= kala).
Hōʻike ʻia nā hiʻohiʻona optical o kahi kānana e kāna pane alapine, e wehewehe ana i ke ʻano o ka hoʻololi ʻana o ka hōʻailona kukui hanana e ka kānana, a hiki ke hōʻike kiʻi ʻia e kāna palapala hoʻouna kikoʻī.
ʻO nā ʻano kānana hoʻopilikino like ʻole:
ʻO nā kānana Absorptive nā kānana maʻalahi kahi i hoʻopili ʻia ai ke ʻano kumu o ka substrate kānana a i ʻole kahi uhi kikoʻī i hoʻopili ʻia a hoʻopaʻa loa ʻia i nā lōʻihi nalu makemake ʻole.
Aia nā kānana paʻakikī hou aʻe i loko o ka māhele o nā kānana dichroic, i ʻike ʻole ʻia ʻo "reflective" a i ʻole "thin film" kānana.Hoʻohana nā kānana Dichroic i ka loina o ke keakea: hoʻokumu ko lākou mau papa i kahi pūʻulu hoʻomanaʻo a/a i ʻole nā papa hoʻomoe, e ʻae ana i ka hana pololei loa i loko o ka nalu i makemake ʻia.Pono pono nā kānana Dichroic no ka hana ʻepekema pololei no ka mea hiki ke hoʻomalu pono ʻia ko lākou mau lōʻihi nalu (ke ʻano o nā kala) e ka mānoanoa a me ke ʻano o nā uhi.Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka nui o ke kumukūʻai a ʻoi aku ka maʻalahi ma mua o nā kānana absorption.
Neutral Density Filter (ND): Hoʻohana ʻia kēia ʻano kānana kumu no ka hoʻēmi ʻana i ka radiation hanana me ka ʻole o ka hoʻololi ʻana i kāna mahele kikoʻī (e like me ke aniani kānana Schott piha piha).
Nā kānana waihoʻoluʻu (CF): ʻO nā kānana kala ke hoʻopaneʻe i nā kānana i hana ʻia me ke aniani kala e hoʻomoʻi i ka mālamalama i kekahi mau pae hawewe i nā degere like ʻole a hāʻawi i ka mālamalama i nā pae ʻē aʻe i kahi ākea.Hoʻemi ia i ka hoʻoili ʻana o ka wela ma o ka ʻōnaehana optical, e hoʻomoʻi pono i ka radiation infrared a hoʻopau i ka ikehu i hōʻiliʻili ʻia i ka ea a puni.
Nā kānana Sidepass/Bandpass (BP): Hoʻohana ʻia nā kānana bandpass Optical no ka hoʻouna ʻana i kahi ʻāpana o ka spectrum me ka hōʻole ʻana i nā lōʻihi nalu ʻē aʻe.I loko o kēia ʻano kānana, hiki i nā kānana holo lōʻihi ke hele i nā hawewe kiʻekiʻe e hele i loko o ke kānana, ʻoiai nā kānana pōkole e ʻae i nā nalu liʻiliʻi e hele.Pono nā kānana loloa a pōkole no ka hoʻokaʻawale ʻana i nā ʻāpana spectral.
ʻO kāna kānana Dichroic (DF): ʻO kahi kānana dichroic kahi kānana waihoʻoluʻu pololei loa i hoʻohana ʻia no ke koho ʻana i kahi ʻāpana liʻiliʻi o nā kala o ka mālamalama a e hōʻike pono ana i nā kala ʻē aʻe.
Nā kānana hana kiʻekiʻe: Loaʻa i ka longpass, shortpass, bandpass, bandstop, dual bandpass, a me ka hoʻoponopono kala ʻana i nā lōʻihi nalu like ʻole no nā noi e koi ana i ka paʻa optical a me ka lōʻihi kūʻokoʻa.
