Latest Patents

One of his latest patents is the Immersion Echelle Spectrograph. This small spectrograph contains no moving components and is capable of providing high-resolution spectra of the mid-infrared region from 2 microns to 4 microns in wavelength. The resolving power of the spectrograph exceeds 20,000 throughout this region, with an optical throughput of about 10.sup.-5 cm.sup.2 sr. The design incorporates a silicon immersion echelle grating operating in high spectral order, combined with a first-order transmission grating in a cross-dispersing configuration. This allows for a two-dimensional (2-D) spectral format that is focused onto a two-dimensional infrared detector array. The spectrometer has wide use potential, including monitoring atmospheric constituents for air quality, climate change, and global warming, as well as monitoring exhaust fumes for smog sources or evidence of illicit drug manufacture.

Another significant patent is for a Durable Silver Coating for Mirrors. This durable multilayer mirror includes reflective layers of aluminum and silver, providing high reflectance over a broad spectral range from ultraviolet to visible to infrared. An adhesion layer of a nickel and/or chromium alloy or nitride is deposited on an aluminum surface, followed by a thin layer of silver. The silver layer is protected by a passivation layer and durability layers made of metal oxides, which improve bonding between nitride and oxide layers.
