    摘要: A photographic apparatus for plate thermography comprising a support having a holder for a thermographic plate at one end and a photographic camera with flashlight at the opposite end. An adaptor designed to be mounted on the support and locked to it is provided for the attachment of different camera systems. Bus bars or contact rails are provided both on the support and in the adaptor so that when the adaptor is placed in position, electrical contact is established between the flashlight and a source of current on the support.
