Optical Components

Aspheres & Freeforms


ZYGO manufactures the world’s most accurate aspherical, spherical and freeform optics. These can be manufactured in sizes up to 600 mm, with surface figure tolerances better than 100 picometers. To put this into perspective, imagine an optic the size of the Unites States with a surface accuracy of less than a millimeter! Extreme precision powered surfaces: Many geometries in sizes up to 600mm: - On-axis and off-axis aspheric. - Freeform (non-rotationally symmetric) - Spherical - Axicon - Kinoform and other diffractive surfaces - Light-weighting and complex mechanical geometries available Click to learn more
