Abstract:
An ultraviolet light imager comprising:a) a camera having: i) a focusable camera lens to receive into the camera ultraviolet light images received from a target; ii) a film holder for film to capture images received from the camera lens, the spacing of the camera lens from the film being adjustable to focus an image on the film; and iii) a camera mirror to reflect light received from the camera lens to provide a reflected image for use in focusing the camera lens, wherein the reflected image is focused to a focusing window; b) an electronic imaging device having an input to receive the reflected ultraviolet image from the camera mirror and provide a viewable output; and c) a viewing system to transmit the reflected image from the camera mirror to the electronic imaging device, the viewing system comprising; i) an optical path from the focusing window to the viewing system input, the optical path having an optical axis; ii) at least one optical element disposed on the optical axis; wherein the viewing system is optically symmetrical on either side of a transverse plane through a mid-point of the optical axis.
