With a total of five patents to his name, Fairchild's work focuses on enhancing the capabilities of optical spectrometers, particularly in dynamic range balancing and minimizing unwanted scattering.

Latest Patents

One of Fairchild's latest patents is titled "Optical Spectrometer Dynamic Range Balancing Methods and Apparatus." This invention facilitates dynamic range balancing for multi-component peaks of varying magnitudes in an optical spectrometer. It employs filters that attenuate the C–H stretch region to improve the fit of a multi-component hydrocarbon Raman spectrum to the dynamic range of a CCD detector. The filter can be translated into and out of the collimated collection beam, allowing for varying degrees of attenuation. In specific applications, the filter can be inserted into a fiber-optic probe head to collect Raman spectra. Additionally, the invention may include optical elements to create the collimated collection beam if they are not already present or suitable for filter insertion.

Another significant patent is "Wavelength Dependent Reflective Sample Substrates for Raman and Fluorescence Spectroscopy." This invention involves a material that is generally transparent in the visible spectrum but reflective at laser wavelengths, which reduces undesirable substrate-induced Raman and fluorescence scattering. The substrate supports the sample, with the material placed between the substrate's surface and the sample. This design minimizes unwanted scattering, allowing for better visibility under a microscope.
