Abstract
An optical viewing instrument, comprises a housing including an eyepiece for viewing a field; a beam splitter within the housing and splitting the field viewed via the eyepiece into a first image for direct viewing by a first observer, and a second image for viewing by a second observer; and a solid state image converter within the housing located to receive the second image and to convert it to electrical signals for reproduction at a remote location.

An optical viewing instrument, comprising:
- a housing including an eyepiece for viewing a field;
- a beam splitter within said housing and splitting the field viewed via said eyepiece into a first image for direct viewing by a first observer, and a second image for viewing by a second observer;
- a solid state image converter within said housing and located to receive said second image and to convert same to electrical signals for reproducing said second image at a remote location;
- a focusing lens within said housing between said beam splitter and said image converter and movable towards and away from said image converter;
- and a manipulatable member on the outer face of said housing coupled to said focusing lens for moving same towards and away from said image converter.

An optical viewing instrument, comprising:
- a housing including an eyepiece having a window at one end for viewing a field along the optical axis of the eyepiece;
- a beam splitter within said housing in alignment with said optical axis and splitting the field viewing via said eyepiece into a first image for direct viewing via said window by a first observer, and a second image for viewing by a second observer;
- a solid state image converter within said housing and located to receive said second image and to convert same to electrical signals for reproducing said second image at a remote location;
- a focusing lens within said housing between said beam splitter and said image converter and movable towards and away from said image converter;
- and a manipulatable member on the outer face of said housing coupled to said focusing lens for moving same towards and away from said image converter;
- said housing including a first section carrying said eyepiece and said beam splitter along the optical axis of said eyepiece, and a second section attached to said first section and enclosing said focusing lens and said solid state image converter in alignment with said beam splitter and perpendicularly to said optical axis.
