The refractive indices of rubidium hydrogen selenate are measured for
several wavelengths at room temperature, and the transmission spectrum
is measured hom the UV (240 nm) to the near IR (2000 nm). The orienta
tion of the optical indicatrix with respect to the crystal axes is als
o determined at several wavelengths in the visible range. Using a new
method based on the deflection of light by the ferroelastic domain str
ucture, we also determine refined values for birefringence at several
wavelengths. Finally, the dispersion of the three birefringences in th
e range 450-900 mo is deduced from polarimetric measurements. This set
of results yields complete knowledge of the linear optical characteri
stics required for interpretation of the electro-optical and nonlinear
optical properties of this compound. (C) 1998 Optical Society of Amer
