Abstract
An optical illumination device includes a light emitting section of discharge type and a condenser mirror placed behind the light emitting section to introduce illumination light into a light transmitting fiber. The light emitting section is placed so that its vertical component is larger than its axial component. In this way, rays from the light emitting section can be efficiently introduced into the light transmitting fiber of small diameter without loss.
