Lensa NIR no ke Kiʻi ʻana i ka Band Infrared Kokoke

ʻO ka Infrared kokoke kahi ʻāpana o ka pūʻulu infrared, aia ma waho o ka laulā spectral kahi i ʻike ʻia e nā maka kanaka. Me ka lōʻihi o ka nalu ma mua o nā kukui ʻike ʻia, hiki i nā kukui NIR ke komo i loko o ka noe, ka uahi a me nā kūlana lewa ʻē aʻe. A ʻaʻole e like me ke kukui MWIR a i ʻole LWIR i loko o ka pūʻulu nalu lōʻihi, ʻo NIR kahi ikehu i hōʻike ʻia e hana like me ke kukui ʻike ʻia.

ʻO ke aniani infrared kokoke (lens NIR) he aniani infrared i hoʻonohonoho pono ʻia no ka ʻāpana infrared kokoke. Ma muli o ka omo ʻana o ka lewa, ma kekahi mau ʻāpana wale nō o ke kāʻei infrared, hiki i ka mālamalama ke hele ma ka lewa a hoʻohana ʻia i nā noi infrared. Ua hoʻolālā ʻia kā mākou aniani NIR e hana ma ka puka makani infrared kokoke ʻelua, a pili i ka mea ʻike infrared kokoke (900-1700 nanometer). He ʻāpana koʻikoʻi loa ia i ka ʻōnaehana kiʻi NIR e pāʻani ana i ka hana like me nā maka kanaka. Me ka ʻole o ka aniani NIR maikaʻi, ʻaʻole ʻoe e loaʻa ka ʻike maopopo i kāu ʻōnaehana.

Hāʻawi ka Wavelength Infrared i nā aniani NIR i ka hana kokoke i ka diffraction-limited. E hele kā mākou mau aniani a pau i nā hoʻokolohua hana optical/mechanical koʻikoʻi a me nā hoʻokolohua kaiapuni e hōʻoia i ka maikaʻi loa.
