title: Assembly of a freeform off-axis optical system employing three φ-polynomial Zernike mirrors.
abstract: We report on the assembly of an off-axis reflective imaging system employing freeform, φ-polynomial optical surfaces. The sensitivity of the system to manufacturing errors is studied for both a passive and active alignment approach. The as-built system maintains diffraction-limited performance in the long-wave infrared.
