Abstract: A method of defining a software configuration for a hyperspectral imaging apparatus includes: creating a plurality of different functionalities, each based on at least one wavelength range; storing one or more of the created functionalities into a hyperspectral image processing model; generating a hyperspectral application for a specific hardware implementation of the hyperspectral imaging apparatus by configuring the hyperspectral application to utilize one or more of the created functionalities of the hyperspectral image processing model; and setting a selection of wavelengths as a control parameter in the hyperspectral application for controlling the specific hardware implementation of the hyperspectral imaging apparatus during an image capture. The selection of wavelengths is based on the wavelength ranges of the utilized one or more created functionalities.

Abstract: Optical radiation from a sample is received by the slit and it is passed through an aperture in a reflective plane of a folding mirror towards a curved reflective surface of a collimating mirror. The slit and the curved reflective surface have a common optical axis. The reflective plane and the curved reflective surface face each other. The optical radiation passed through the folding mirror is collimated by the curved reflective surface. The collimated optical radiation is directed to the reflective plane of the folding mirror by the curved reflective surface. The collimated optical radiation is reflected in a direction other than the common optical axis of the slit and the curved reflective surface by the reflective plane.
