<p>A method and device for positioning a viewing objective and an alternate objective in relationship to a viewpoint and/or a light energy source are provided. A plurality of objective lenses are coupled with a carriage plate. The carriage plate moves along a single axis and positions the objective lenses for use in delivering a laser beam to an object and/or enabling observation of the object by a human operator. A version includes a linear turret or "optical turret" for positioning at least one objective relative to a light energy source, where the optical turret is communicatively coupled with a processor and the optical turret includes (1) at least one objective; (2) a carriage plate, (3) a linear rail, (4) a scale, (5) a sensor, and (6) a linear motor.</p> |
