Latest Patents

One of Schumann's latest patents is a spectrum analyzing system with a photodiode array. This innovative system measures or analyzes the colorimetric properties of a test sample at preselected wavelengths within the ultraviolet, visible, and near-infrared regions. The system includes a spectrophotometer with a wideband light source, optical devices for sample and reference light paths, and a chopper wheel for directing light alternately. It also features a dispersion grating, neutral density filters, and a linear array of photodiodes for detecting dispersed light at different wavelengths. The electronic control section includes a programmable power supply to control light intensity, ensuring optimal operation of the photodiode array.

Another significant patent is the apparatus for textile color analysis. In this invention, a textile sample is supported on an elevator mechanism that holds it against an instrument head. The head features an opaque housing with a chamber and a glass plate that provides a stable reference plane. An illuminating fiber optic bundle directs light perpendicularly to the textile sample, while additional fiber optic bundles receive diffuse light reflected from the sample. The elevator mechanism includes a translucent polyethylene pad that backs up the textile sample, eliminating adverse effects from light showing through.
