Abstract
An illumination device for an optical viewing apparatus has a light source including a first individual light source and a second individual light source arranged in a plane. The first individual light source has a first midpoint and the second individual light source has a second midpoint. An axial direction is defined by a vector from the second midpoint to the first midpoint. An illumination optical unit defines an optical axis which is arranged perpendicularly to the plane and intersects the plane at an intersection point. The light source is imaged toward infinity by the illumination optical unit. The first individual light source has an extent along the axial direction. The midpoint is offset by an amount (Δ) in a positive direction along the axial direction relative to the intersection. The relationship 0.1*L≦Δ≦1*Lis satisfied for the offset.
