We describe the methodology and results of the achieved high optical quality factor of the Fabry-Perot (FP) interferometers making a basis of the measurement system of the gravitational antenna OGRAN. We present a full optical scheme of the facility as well as the features of the mechanical design of the opto-acoustic resonators.
