Abstract
An optical connector comprises a series of transparent substrates 50-53 including a refraction type lens 10 embedded in the central substrate 50, two beam deflection elements 40 and 41 offset from the optical axis of the lens 10, a light emitting element 20 directly below the beam deflection element 40, and a light detecting element 30 directly above the beam deflection element 41. The lens 10 is designed to have identical meridional and sagittal focal lengths so that meridional and sagittal images of obliique incident beams may be formed on the same spot on the light detecting element 30. Beam of light emitted from the light emitting element 20 are deflected by the beam deflection element 40 and enters the lens 10 obliquely. The beams, passing through the lens 10 and the deflection element 41 are cllimated within a small spot on the light detecting element 30 since the lens 10 has identical meridional and sagittal focal lengths.
