Claim:
1. A method for determining a spectral regime of operation of a spectrometric device that is cooperated with a sample, the device enabled to generate optical waves and configured to measure a property of a material component of the sample, the method comprising: receiving at a user-input device, optical data obtained with light from a set of light sources of said spectrometric device and representing spectrally-dependent characteristics of M material components of the sample to be measured with the spectrometric device having at least one optical detector, M being greater than 1; forming a first system of equations that expresses the optical data as functions of at least forming a second system of equations including the first system of equations and additional equations employing at least one parameter representing operational utility of the device; and solving said second system of equations, with a programmable processor, to calculate such N wavelengths of operation of the device that a spectrally-dependent figure of merit is locally optimized at the wavelengths of operation, wherein to solve said second system of equations a number N of calculated wavelengths of operation smaller than the number M of the material components is required, and wherein said spectrally-dependent figure of merit includes propagation of variance, and transforming said set of light sources by replacing at least one light source from said set to form a transformed set of light sources that generate light at said N of calculated wavelengths.
