Title: Innovations of Ramdane Benferhat
Introduction
Ramdane Benferhat is a notable inventor based in Oncy sur Ecole, France. He has made significant contributions to the field of optical analysis, holding three patents that showcase his innovative approach to sample analysis.
Latest Patents
One of his latest patents is a system and process for analyzing a sample. This invention includes an excitation section and an analyze section. The excitation section features a light source that emits an incident measurement luminous beam, along with a polarization state generator and first optics. The analyze section comprises a polarization state analyzer, a detection system, and second optics. This system allows for detailed analysis by directing luminous beams toward the sample surface along a precise optical axis.
Another significant patent is an achromatic spectroscopic ellipsometer with high spatial resolution. This device is designed for analyzing small regions of a sample across a wide range of wavelengths, from ultraviolet to infrared. The spectroscopic ellipsometer utilizes a light source that passes through a polarization state generator before being focused onto a small spot on the sample by a parabolic mirror. The reflected beam is then collected and analyzed, ensuring achromatism and allowing for a variable incidence angle without shifting the spot's location.
