New Jersey Patent of the Month – February 2021
Fluorescence contributes to color samples. A standard color measurement device uses a spectral sensor to obtain spectral information from a color sample. However, these devices cannot separate fluorescent properties of a sample from the reflective properties of the device and therefore produce some inaccurate data. Expensive spectrofluorometers are needed to fully characterize the fluorescence of a sample. Datacolor, Inc decided to design affordable fluorescence measuring software to make sure this technology becomes attainable.
Their design uses a sample which is illuminated under one or more narrow-band light sources. If the sample is reflective, the light is directed at the sample from the same direction of the sensor. If the sample is transmissive, the light is directed at the sample from the opposite direction, so that the light passes through the sample to arrive at the sensor.The light incident upon this is received by a color sensor that generates measurement data, such as a spectrometer or photodiode array. The color sensor is connected to a processor, either wirelessly or wired, which receives the data and derives fluorescent profile values as a final product. The software designed by Datacolor would derive this data using calculations to first obtain fluorescent and excitation response curves which are further processed to create excitation and fluorescence profiles. They intend for the software to be able to work with most sensors so that the fluorescent measuring capabilities can be used by industry professionals as well as hobbyists.
Datacolor aims to empower their customers to make objective, cost-effective and smart color decisions that perfectly suit individual workflows. Over a million customers working in Textile & Apparel, Paint & Coatings, Plastics, Photography, Design and many other industries trust Datacolor solutions.
