Aspheric and Parabolic Mirrors
Excelitas offers aspheric and parabolic mirrors which provide extremely accurate surface form and low sag deviation accuracies as low as ½ fringe making these ideal for a variety of demanding infrared imaging and military target designation applications.
Aspheric and parabolic mirrors are fabricated from aluminum or copper substrates and can be produced in sizes up to 12 inches (300 mm) with virtually any aspheric profile including both rotationally and non-rotationally symmetric, such as cylindrically aspheric and toroidal curves, as well as off-axis parabolas.
