Title: Innovations of Thomas W. Barnard
Introduction
Thomas W. Barnard is a notable inventor based in Weston, CT (US). He has made significant contributions to the field of optical spectrometry, holding a total of 5 patents. His work has advanced the capabilities of spectrometers, particularly in detecting various spectral ranges.
Latest Patents
One of his latest patents is an optical spectrometer designed for detecting spectra in separate ranges. This innovative spectrometer utilizes a pair of crossed reflective gratings to create a spectrally dispersed beam that is focused onto an array detector. The second grating features a plural design, with a surface divided into two portions. The first portion is optimized for ultraviolet detection, while the second portion is tailored for visible radiation. A shutter mechanism allows for the selection of either spectral range for detection. Additionally, the grating surface can be contoured to correct for aberrations in the beam's focus. A computer system is employed to select specific spectral lines for analysis, particularly those in the second range that are unaffected by the first.
Another significant patent by Barnard is a spectrometer with selectable radiation from an induction plasma light source. This atomic emission spectrometer incorporates an induction-coupled plasma generator and a sophisticated detector system. It features a series of mirrors strategically positioned to capture both axial and radial radiation from the generator. The first mirror can be rotated to direct either type of radiation into the detector system, enhancing the versatility of the device.
