SEBI RT1000 is a high-resolution wavefront sensor based on Wavefront Phase Imaging (WFPI) technology, designed for precision optical metrology and beam characterization. It delivers nanometric optical path difference repeatability, full-field 1000 × 1000-pixel wavefront measurements, and high spatial resolution at video rates. SEBI RT1000 enables non-contact characterization of optical components, laser beams, adaptive optics systems, and optical surface quality, while providing an intuitive software suite and SDK for seamless integration into research, industrial, and defense applications.
