Off-Axis Parabolic Mirrors are mirrors whose reflective surfaces are segments of a parent paraboloid. They achromatically focus a collimated beam or collimate a divergent source, and their off-axis design separates the focal point from the rest of the beam path. The reflective design eliminates phase delays and absorption losses introduced by transmissive optics and makes these well suited for use with femtosecond pulsed lasers.
