description: In this work, powdered thin films of hexagonal boron nitride were studied using polarization spectroscopy in the visible optical region. The birefringence effect was discovered during the analysis of the spectral dependences of the Stokes parameters in the transmission spectra. The selected optical axis did not change over the entire surface of the sample. The odds are that this effect is caused by spatial anisotropy of the distribution of microcrystals in the powder. Using the Maxwell-Garnett model, it was found that the anisotropy of the refractive index of the sample is 0.08. To estimate the anisotropy of the refractive index of light, the program was written in MatLab. It was used to estimate the anisotropy of the spatial distribution of microcrystals based on the analysis of images from an optical microscope. It was obtained that the spatial anisotropy ranged from 0.06 to 0.10 for different images. The results of the work can be used in further studies related to the creation of van der Waals heterostructures.
