noi huahana

Hoʻohana nui ʻia ka Whiteness Meter i ka hana pepa, lole, paʻi, plastic, ceramic a me porcelain enamel, mea kūkulu hale, ʻoihana kemika, hana paʻakai a me nā keʻena hoʻāʻo ʻē aʻe e pono e hoʻāʻo i ke keʻokeʻo. Hiki i ka mika keʻokeʻo ke hoʻāʻo i ka ʻike o ka pepa, ka opacity, ka hoʻoheheʻe māmā a me ka coefficient absorption māmā.

Nā kūlana ʻenehana

1. E like me GB3978-83: ʻO nā kukui maʻamau a me nā kukui a me nā kūlana nānā.
2. E hoʻohālikelike iā D56. ʻO ke anawaena diffuse he 150mm a ʻo ke anawaena holoʻokoʻa he 30mm a i ʻole 19mm. Hoʻohana ʻo ia i ka mea hoʻomaʻamaʻa māmā e hoʻopau i ka mana i hana ʻia e ke aniani o ka specimen e hōʻike ana i ka mālamalama.
3. ʻO R457 keʻokeʻo keʻokeʻo spectral mana hāʻawi ʻōnaehana i ka peak wavelength 457nm, FWHM 44nm, RY10 optical system ma ka laina me ka GB3979-83: ke ana kala mea.
