Latest Patents

Hunter's latest patents include the "Discrete Vacuum Ultra Violet Reflective Interference Filter" and the "Interference Photocathode." The Discrete Vacuum Ultra Violet Reflective Interference Filter is a thin film reflecting interference filter designed to suppress unwanted harmonics, thereby improving the monochromaticity of radiation. This invention utilizes an interference layer with well-defined plasma oscillation, which is deposited on a substrate. A mismatch layer is formed to enhance reflectance at the vacuum-layer interface, allowing for more complete destructive interference of unwanted harmonics. The filter can be tuned by adjusting the layer's thickness, composition, or the angle of incidence of the radiation.

The Interference Photocathode features a reflective substrate with interference layers that selectively enhance the photoelectric yield for specific wavelengths. This design allows for improved efficiency when irradiated by radiation of different wavelengths. The interference layers include a dielectric layer with a wavelength-dependent effective thickness, optimizing performance for both the first and second wavelengths.
