Latest Patents

Massaaki Ito holds a patent for "Methods for measuring optical system, and method and apparatus for." This invention presents a technique and exposure apparatus that measures, with a high degree of accuracy, figure and placement errors of individual optical elements within an exposure apparatus. The system operates while keeping the optics in an embedded state, allowing for precise measurements of wavefront distortions. By adjusting the positions of a light source and an image point, the system calculates optimal displacements of reflective surfaces based on the measured distortions. Ultimately, the reflective surfaces are corrected through individual control of displacements by actuators and mechanical modifications.
