    Abstract: A method of making a colorimeter colour standard, including determining print parameters required to achieve a desired colour for the colour standard, printing the desired colour on a colour-receiving face of a first transparent piece using the determined print parameters and permanently affixing the printed first piece to a second transparent piece such that the colour-receiving face of the first transparent piece and a joining face of the second transparent piece are positioned at the interface between the first transparent piece and the second transparent piece.

    Abstract: An example method includes receiving a first set of data that includes spectral metrics provided by a spectral acquisition apparatus that obtains the spectral metrics based on interactions of electromagnetic radiation with a sample. The first set of data is processed to obtain a second set of data that includes the spectral metrics. One or more trained models are applied to the spectral metrics or a set of values based on the spectral metrics to obtain a result. Based on the result, either a positive particle of interest detection or a negative particle of interest detection for the particle of interest for the sample is determined. A particle of interest detection notification that indicates either the positive particle of interest detection or the negative particle of interest detection for the particle of interest for the sample may be generated and provided.

    Abstract: A device for radiometrically gauging the surface of a measurement object (O) includes: at least one measurement array featuring an illumination array and a pick-up array; and a processor (P) for controlling the illumination array and the pick-up array and for processing measurement signals produced by the pick-up array and for providing processed image data. The illumination array exposes a region of the measurement object (O) to illumination light at an illumination angle (θi) and an illumination aperture angle (αi), and the pick-up array captures measurement light, reflected by the measurement object (O), at a pick-up angle (θv) and a pick-up aperture angle (αv) and guides it onto an image sensor exhibiting a pixel structure. The measurement object (O) is gauged multispectrally in multiple wavelength ranges, wherein the image sensor produces multispectral image data. Angular and spatial conditions are indicated which optimise the measurement device (MD) with regard to characterising sparkles.
