Latest Patents

One of Somerstein's latest patents is the "Binary half-tone photolithographic optical apodization mask." This invention discloses a method for creating an apodization mask by generating a grid with multiple elements. Each element is processed to determine its transmissive properties based on a predetermined local optical density and a random value. The method also includes a positional shift for the elements, which is determined randomly. This grid is then utilized to create an apodization mask that can be applied in optical instruments, such as interferometers.

Another significant patent is the "Enhanced waveguide metrology gauge collimator." This invention describes a free-space optically-coupled collimator designed for efficient bidirectional transmission of an optical metrology beam. The collimator is contained within an isothermal nested enclosure, ensuring that the waveguide element is mounted in a stress-free manner. The focus of the collimator aligns with the waveguide aperture, optimizing the transmission of the optical metrology beam.
