Abstract
An apparatus includes an in-line reflective optical system configured to receive an input optical beam and provide an output optical beam. The in-line reflective optical system includes first and second powered mirrors aligned back-to-back. The first powered mirror is configured to reflect the input optical beam as a first intermediate beam. The in-line reflective optical system also includes first and second reflective surfaces respectively configured to reflect the first intermediate beam as a second intermediate beam and to reflect the second intermediate beam as a third intermediate beam. The second powered mirror is configured to reflect the third intermediate beam as the output optical beam. A spacing between the first and second reflective surfaces and the first and second powered mirrors is adjustable to control a focus of the output optical beam without introducing boresight error in the output optical beam.
