Optical constants of Diesel soot
Querry 1987: Sample 1, heated; n,k 0.260–55.6 µm
Complex refractive index (n+ik)
Derived optical constants
Diesel soot sample obtained at New Mexico State University by open burning of diesel fuel. Sample heated to to about 320 °C for about one-half hour to drive off any unburned hydrocarbons.
