Some results of calculation of the extinction coefficient of immersion particles of the BS–4 glass as functions of the difference between the refractive indices of the glass and immersion liquid and the absorption coefficient of particles are presented. It is shown that when the difference between the refractive indices is small the immersion method ensures satisfactory accuracy of determining the absorption coefficient.
