OPTICAL MEMBER Russian patent published in 2006 - IPC G02B1/00 G02B1/06 G02B3/12 G02B26/00 

FIELD: optical devices with variable optical parameters, applicable in manufacture of miniature objective lenses with a variable focal length.

SUBSTANCE: the optical member has a container. The container comprises two transparent immiscible liquids with various indices of reflection. They are transparent in the area of operating wave-lengths. The first one is a dielectric. The second one features the properties of electric conduction. The liquids are engageable with each other with formation of an interface separating them. The interface curvature determines the optical parameters of the optical member. For control of the curvature of this interface the container is provided wits electrodes. A porous matrix with liquids with formation of an interface separating them is performed by impregnation.

EFFECT: developed a modification of an optical member with variable optical parameters using the effect of curvature of the interface formed on the boundary of engagement of two immiscible liquids with various indices of reflection, adapted to mass reproduction and featuring a stability to mechanical actions.
