Abstract
Systems and methods for dispersing an optical beam are disclosed. In one implementation, an optical system includes a first double Amici prism and a second double Amici prism. The first and second double Amici prisms are aligned along an optical axis of the system and configured to transmit the optical beam. At least one of the first and second double Amici prisms is rotatable relative to the other around the optical axis. Advantageously, the disclosed systems and methods allow for efficient and versatile adjustment of the magnitude and/or orientation of the dispersion of the optical beam.
