A design of a liquid doublet for optical systems has been developed that has the ability to compensate for gravitational distortions. During the development process, the liquid doublet designs were examined, and the physicochemical properties of the liquids used were investigated to minimize the gravity influence on the elastic membrane shape of the liquid doublets. When selecting the liquid combinations, special attention is paid to the parameters such as refractive index, dispersion coefficient, density, viscosity, and the dependencies between them. The results obtained in the form of line targets and angular resolution, demonstrate the feasibility of using a liquid doublet with an elastic membrane separating the liquids, although it is not final and require further research to minimize any spherical aberration in the optical system.
