A slide holding a film with an image containing portion adapted for use in an application such as Night Vision Goggle training in which the film in the slide is to receive an extremely low level of light. A combination of filters is placed adjacent the light receiving face of the film and an opaque mat having a cutout corresponding to the film image bearing portion is placed adjacent both the light receiving side of the filters and the light output face of the film to reduce the amount of stray light reaching the film with the components held together by a pair of frame members each holding a glass plate next to a mat.
