ABSTRACT:
A system for evaluation of optical quality of an optical device includes a light source configured to generate light, the generated light be received by an optical device. An interferometric lens apparatus is removably mounted to the optical device to generate interference fringes. A camera device is configured to receive and display the interference fringes, and a computer configured to analyze the interference fringes received from the camera device to determine aberrations of the optical device and generate a recommendation to correct the determined aberrations. Methods for evaluating the optical quality of an optical device are also described.
