Blood refractive index modelling in the visible and near infrared spectral regions

Abstract

We present the calculation of blood refractive index based on the experi-mental data for the real part of the refractive index of the main protein components, haemoglobin and albumin. The refractive index of blood proteins was measured using the multi-wavelength Abbe refractometer at the wavelengths 480, 486, 546, 589, 644, 656, 680, 930, 1100, 1300, and 1550 nm at room temperature +24°С.
