Abstract: Apparatus for combining an optical and laser system as, for example, in weapons systems where sighting an observation is to be employed and wherein the optical channel may be a sighting device such as a periscope and wherein the laser may comprise a laser transmitter for telemetry or for the purposes of Identification Friend or Foe. The transparent optical system transmits light wave energy and also includes the emission range of the laser transmitter. There are problems of mounting the two systems due to space limitations and in the present invention the output of the laser radiation into the optical system is accomplished by the use of optical fiber bundles which extend from the laser transmitter to the optical system.
