1.67 Kiʻekiʻe Index Hoʻopau Polū Māmā kānana Lens

Loaʻa ka nalu a me ka ikehu mai ka 380 nm (ka ikehu kiʻekiʻe a hiki i ka 500 nm (ka ikehu haʻahaʻa).
No laila, ʻo kahi hapakolu o nā kukui ʻike ʻia he kukui polū

Hoʻokaʻawale hou ʻia ke kukui polū i kēia mau pūʻulu (kiʻekiʻe i ka ikehu haʻahaʻa):
· Māmā ʻulaʻula (ma kahi o 380-410 nm)
· Māmā ʻulaʻula-ʻulaʻula (ma kahi o 410-455 nm)
· Māmā polū-turquoise (ma kahi o 455-500 nm)

Ma muli o ko lākou ikaika kiʻekiʻe, ʻoi aku ka maikaʻi o nā kukuna violet a me ka uliuli-violet e hōʻino i ka maka.No kēia kumu, ua kapa ʻia kēia mau kukuna (380-455 nm) he "kukui polū pōʻino."

ʻO nā kukui kukui polū-turquoise, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka liʻiliʻi o ka ikehu a ʻike ʻia e kōkua i ka mālama ʻana i kahi pōʻai hiamoe maikaʻi.No kēia kumu, ua kapa ʻia kēia mau kukuna (455-500 nm) i kekahi manawa he "mālamalama polū maikaʻi."

Aia nā kukuna ultraviolet ʻike ʻole ʻia (UV) ma mua o ka hopena kiʻekiʻe (violet) o ke kukui ʻulaʻula uliuli.Ua hōʻike ʻia ka radiation UV i ka pōʻino i nā maka a me ka ʻili.
