Off-Axis Parabolic Mirror
An off-axis parabolic mirror is an optical element capable of perfectly focusing parallel light to a single point or transforming light emitted from a point source into parallel light.
An off-axis parabolic mirror can effectively eliminate spherical aberration. As a purely reflective optical element, it eliminates chromatic aberration and avoids the phase delays and absorption losses that may occur with transmissive optical components.
