Ihe nzacha njupụta/ntụgharị uche na-anọpụ iche

Njupụta anya (OD) na-egosi ihe attenuation nke ihe nzacha anya na-enye, ya bụ ole ọ na-ebelata ike anya nke ìhè ihe merenụ. OD metụtara nnyefe. Ịhọrọ nzacha ND nwere njupụta ngwa anya dị elu ga-atụgharị gaa na mbufe dị ala na nnabata ka ukwuu nke ọkụ ihe merenụ. Maka mgbasa ozi dị elu na obere nnabata, njupụta anya dị ala ga-adabara. Dịka ọmụmaatụ, ọ bụrụ nzacha nwere OD nke 2 na-ebute uru nnyefe nke 0.01, nke a pụtara nzacha na-eme ka ọkụ ahụ dịkwuo 1% nke ike ihe merenụ. Enwere ụdị abụọ nke ND filiters: ihe nzacha njupụta na-anọpụ iche, ihe nzacha njupụta na-anọpụ iche.
