An infrared seeker for use in a spinning projectile is shown to include a Cassegrainian telescope having a tapered optical wedge overlying the entrance aperture, such wedge being rotatably mounted to allow scanning and tracking, and a jettisonable streamlined cover overlying the optical wedge to reduce drag so long as such cover is in place.
