The optical properties of 1 μm polystyrene in the wavelength range of 500–750 nm were estimated by using a white light spectrophotometric transmittance spectroscopy and a single integrating sphere system.
To retrieve the optical characteristics, two analytical methods, namely, diffusion approximation and Kubelka–Munk were used, and then their results were compared with Mie theory calculations.
The correspondence of the Kubelka–Munk scattering coefficient with Mie was obvious, and relative errors varied between 6.73% and 2.66% whereas errors varied between 6.87% and 3.62% for diffusion theory.
Both analytical methods demonstrated the absorption property of polystyrene over the abovementioned wavelength range.
Although absorption coefficient turned out to be much lower than scattering, constructing a realistic optical phantom requires taking into account absorption property of polystyrene.
Complex refractive index of polystyrene based on these two methods was determined.
Inverse Mie algorithm with scattering coefficient was also used to retrieve the real part of refractive index and absorption coefficient for calculating the imaginary part of refractive index.
The relative errors of the real part did not exceed 2.6%, and the imaginary part was in consistence with the prior works.
Finally, the presented results confirm the validity of diffusion theory with a single integrating sphere system.
