Abstract
An optical system may include an objective lens system having a primary optical axis and a relay lens system having a relay optical axis. The relay optical axis may have a first angular offset with respect to the primary optical axis. The objective lens system may be configured to provide light from a light source to the relay lens system and provide light from the relay lens system to an image sensor. The relay lens system may be configured to provide light from the objective lens system to an end face of an optical fiber, where the end face has a second angular offset with respect to a cross-sectional axis of the optical fiber. The relay lens system may provide light reflected from the end face to the objective lens system.
