Polyurethane-located aerogels have been combined and their optical properties intentional in detail. The forceful and direct relationship between the fundamental features of the presented materials with the conclusive light transmittance admitted to analyze the uneven mechanisms. Thus, through the modification of the beginning polyurethane formulations tunable structures were acquired and, consequently, their final ocular properties were tailor-made. In this way, for aerogels with networks formed by limited particles and pores, the topmost transmittances were reached (85% at 650 nm). However, these principles were progressively reduced accompanying the enlarging of the fundamental features owing to the light uneven that they produce. Then, the transition through Rayleigh uneven to Mie scattering was determined by weighing the light transmittance at a expansive range of light wavelengths (UV-Vis). Additionally, the Beer-Lambert law was verified for all the aerogels substitute through the effect of the sample thickness on the conclusive transmittance. Therefore, the ocular properties of polyurethane aerogels were studied painstakingly, obtaining aerogels accompanying tunable transmittances which opens a wide range of requests in building and strength sectors such as glazing bays.
