From: Measurement of refractive indices of tunicates’ tunics: light reflection of the transparent integuments in an ascidian Rhopalaea sp. and a salp Thetys vagina

Fig. 5

Reflectance (%) of 633 nm light [TE wave (a, c) and TM wave (b, d)] on the flat surface (solid line) and on the model of Thetys vagina tunic surface (dotted line). The difference in refractive index between the tunic and medium (seawater) were assumed to be −0.04, −0.02, 0.02, and 0.04. c and d show enlargements of a and b, respectively
