Nā kānana hoʻopaʻa haʻahaʻa hoʻoheheʻe / noʻonoʻo

Hōʻike ʻo Optical density (OD) i ke kumu attenuation i hāʻawi ʻia e kahi kānana optical, ʻo ia hoʻi ka nui o ka hoʻemi ʻana i ka mana ʻikea o kahi kukuna hanana. Pili ka OD i ka lawe ʻana. ʻO ke koho ʻana i kahi kānana ND me kahi kiʻekiʻe optical density e unuhi i ka haʻahaʻa haʻahaʻa a me ka hoʻonui ʻana o ka mālamalama hanana. No ka hoʻouna kiʻekiʻe a me ka liʻiliʻi o ka absorption, kūpono ka haʻahaʻa optical haʻahaʻa. No ka laʻana, inā loaʻa kahi kānana me kahi OD o 2 i ka waiwai hoʻouna o 0.01, ʻo ia ke ʻano o ka kānana e hoʻemi i ke kukui i 1% o ka mana hanana. ʻElua mau ʻano o nā filiters ND: nā kānana hoʻopaʻapaʻa kūpaʻa absorptive.
