Filed: 1994-05-17
Abstract: PURPOSE:To easily and surely prevent flare and ghost generated by a reflected light beam from an imaging device without restricting the design of an optical system by providing a specified light shielding means for shielding harmful light. CONSTITUTION:Since a reflected light beam is a cause of vacuum flare and ghost, by providing a light shielding means 10 in a part (alpha part) where an effective light beam 3 and reflection beam 4 is separated, the generation of the vacuum flare and ghost are prevented or eliminated to a level of having no practical problem. Namely, in the image pickup optical system, in order to separate the reflection beam 4 by the image pickup plane 2 and a specified reflection part 8 affecting a picture from the effective light beam 3, by making the effective beam 3 obliquely incident on the image pickup plane 2 and providing a light shielding means 10 for shielding the reflected beam 4 in the separating part alpha for separating the effective beam 3 from the reflected beam 4, the inconvenience due to the vacuum flare and ghost is suppressed.
