Radius

Controls: Radius of curvature of a spherical surface at minimum RMS irregularity, spherical power of a plano surface or vertex radius of asphere

Related Terms: Radius of Curvature, Power

Units: Linear units for radius, wavelengths or half-wavelengths (fringes) for power

Specification Must Contain: Nominal radius value and fringes of power over an aperture or a nominal radius value with linear or percent deviation from nominal over an aperture

Optimax Preferred Specification: Radius deviation for spherical and aspherical, fringes power for plano

Reasons: Radius is directly measured on an interferometer for radii with interferometric coverage or with a profilometer for aspheres and long spherical radii without interferometric coverage.
