Latest Patents

Among Hubert Jean-Ruel's latest inventions is the **Multi-pass etalon filter**. This groundbreaking invention relates to a multi-pass etalon-based optical filter designed to improve etalon contrast by reflecting input light multiple times. The external mirror's ability to tilt relative to the etalon allows for orthogonal planes of incidence, making it highly effective in eliminating scattered light from excitation wavelengths in Raman and Brillouin spectroscopy.

Another of his notable patents is the **Etalon based optical spectrometer**. This improved optical spectrometer addresses limitations found in conventional etalon-based systems, which often had restricted evaluation wavelengths and required continuous etalon scanning. By integrating a cylindrical lens that converges the input beam of light, the innovative design focuses the beam along a focal line. This advancement enables a first etalon to transmit a series of sub-beams at varying angles and frequencies, allowing for greater detail and contrast with the help of a secondary dispersive element.
