SYSTEM AND METHOD FOR CALIBRATING OPTICAL CHARACTERISTICS
First Claim
1. A method for determining optical characteristics of an object comprising:
- storing a plurality of optical property parameters for each of a plurality of shades;
calibrating the stored plurality of optical property parameters by measuring optical properties of a test object;
replacing the stored plurality of optical property parameters with the calibrated plurality of optical property parameters;
measuring optical properties of the object with an instrument;
comparing the measured optical properties of the object to the stored calibrated optical property parameters;
determining one or more shade match candidates according to the comparing; and
displaying the one or more shade match candidates on a display device.

Abstract
A miniaturized spectrometer/spectrophotometer system and methods are disclosed. A probe tip including one or more light sources and a plurality of light receivers is provided. A first spectrometer system receives light from a first set of the plurality of light receivers. A second spectrometer system receives light from a second set of the plurality of light receivers. A processor, wherein the processor receives data generated by the first spectrometer system and the second spectrometer system, wherein an optical measurement of a sample under test is produced based on the data generated by the first and second spectrometer systems.
