FIELD: optical tools.
SUBSTANCE: invention relates to the relay optics for a rigid endoscope. Relay optics (1) contains two identical lens systems (2) that are located symmetrically to each other relatively to perpendicularly laying optical axis (O) of symmetry plane (A). Each lens system (2) contains first biconvex lens (4), biconcave lens (5), rod lens (6) that has convex lens surface (F5) facing plane (A) and convex lens surface (F6) opposite to plane (A), and second biconvex lens (7) in this sequence, when viewed from symmetry plane (A).
EFFECT: invention provides for a decrease in image distortions.
