ABSTRACT:
An optical system (10) comprises a camera (11) having an imaging means that in use faces downwardly, and an optical assembly. The optical assembly includes a support (14) that extends outwardly from the camera (11) and which has a lumen therethrough to allow transmission of light through the support (14) to the imaging means of the camera (11). The assembly further includes an optical unit (16) mountable to the support (14) and movable relative thereto towards and away from the imaging means of the camera (11). The optical unit (16) includes at least one lens (17) and a mirror assembly (22, 23) adapted to reflect at least some light entering the unit (16) that is at approximately a right angle to the orientation of the camera (11), through the lens (17) and into the lumen of the support (14) to the imaging means. The system (10) can be mounted to a headpiece worn by a user, such as a surgeon.
