Mune milaffairs, iyo yakajairwa mwenje sosi yemidziyo yekuvhenekesa mukamuri yeinjini haingope chete kuvhenekera, asi zvakare inoburitsa mwenje mupedyo infrared bhendi. Kunyangwe kusimba kwechiedza kusina kukwirira, kunokonzera kumwe kupindira kuNVIS (husiku hunoenderana system). Parizvino, yakananga uye inoshanda nzira yekubvisa rudzi urwu rwekukanganisa ndeye kushandisa pedyo infrared sefa. Izvi hazvingoite kuti chiono chehusiku chienderane nehurongwa hushande zvakajairwa, asi zvakare zvinoita kuti zviome kuhurongwa hwekuona husiku hwemuvengi kuti atiwane mukati mechimwe chinhambwe.

Parizvino, magirazi ekuona ehusiku akadzika-mwenje akagadziridzwa kusvika kuchizvarwa chechina, uye bhendi rekuita rakafanana nerechizvarwa chechitatu (625 ~ 930 nm), asi kunzwisiswa kunowedzera. Tsvagiridzo yerudzi urwu rwepadhuze-infrared sefa inonyanya kuve yakavakirwa padhuze-infrared epurasitiki sefa inogadzirwa muUnited States uye iri padyo-infrared girazi sefa inogadzirwa muGermany, nepo nhanho yekusimudzira yepamba iri kumashure, uye hapana pedyo-infrared sefa inogona kusangana nezvinodiwa zvekuenderana kwekuona kwehusiku.

Kiyi yekugadzira mafirita ari pedyo-infrared anosangana nezviyero zvemauto ndeye kushandisa akavharidzirwa ari pedyo-infrared absorption dhayi, nekuti haasi ese ari pedyo-infrared absorption dhayi anogona kusangana nezvinodiwa. Kuti isangane nezvinodiwa zvekuenderana kwekuona kwehusiku, iyo iri pedyo infrared absorber inogona kushandiswa yoga, musanganiswa kana kusanganiswa neakajairika mapurasitiki dhayi, kuitira kuti iite spectral amplitude uye kupenya kwayo NR kukosha kuenderane ne -1.0E + 00≤ NR ≤ 1.7E-10, uye chromaticity yayo yegirinhi usiku inosangana nezvinodiwa zvehusiku girinhi A, kuona kwehusiku girinhi A. tsvuku nehusiku chiratidzo chichena), uye kufambiswa kwechiedza chinooneka hakusi pasi pe20%.

Pedyo infrared absorbers inonyanya kusanganisira cyanine dhayi, phthalocyanines, quinones, azo dhayi uye simbi complexes. Zvakanakisa kuti iyo infrared absorber ine yakaderera kunyura mwero munzvimbo inooneka yechiedza, yakanyanya kunyura inoshanda munzvimbo iri pedyo infrared uye seyakakura kunyura sezvinobvira. Kugadzirira kweoptical sefa kunotora dhayi + polymer tekinoroji, inogona kuputirwa pamusoro kana kuwedzerwa panguva yepolymerization.
