  • Patent number: 4153333
    Abstract: An image transmitting optical fiber bundle has at an end of it a field stop for defining the size of image viewed thereby. The field stop is sandwiched between a pair of transparent thin plastic films. The pair of films which sandwiches the field stop is fixed to an end of the optical fiber bundle. A face plate is further fixed on the pair of films on the end face of the fiber bundle. Since the surfaces adhered are all flat, the formation of bubbles in the adhesive is easily precluded.
