LENS MODULE Russian patent published in 2011 - IPC G02B7/02 G02B27/04 

FIELD: physics.

SUBSTANCE: lens module has at least two mountings, each having at least one lens-type optical element. The mountings are pivotally connected to each other in form of a chain and can turn about the swivelling joints. The chain of mountings lies between two mirrors and can change its configuration from transporting to working state. In the transporting state, the chain is flattened and optical elements in different mountings have differently directed optical axes which form with each other angles close to zero degrees. In the working state, the configuration of the chain changes such that optical elements together with two mirrors form the optical system of the lens, having one common optical axis formed due to reflection from the mirrors.

EFFECT: less restrictions on cameral thickness.
