Paper Abstract

Narcissus is caused by the reflection of the cold stop off a lens surface back to the image plane of a cooled infrared system and can be very difficult to remove from a lens design perspective. New infrared GRIN materials show the ability to reduce the amount of narcissus in an optical system without the reduction in performance or addition of optical elements.
