ABSTRACT OF THE DISCLOSURE Apparatus is disclosed which is employed for viewing an enlarged image. The apparatus is of the type having a projection lens system for providing a projected image of an object along an optical path to a reflect- ive surface and through a field lens to a moving reflective projection screen where the image is viewed through a viewing lens and the field lens. The reflective projection screen comprises a light weight flexible laminated disc having at least a lenticular layer and a highly reflective layer. The flexible laminated disc, when rotated at high speeds, provides a self- balancing projection screen which assumes a substantially flat lenticular plane.
