Abstract
Spectrometer for recording a spectrum, in particular in a wavelength range of 250 nm to 1150 nm, comprising: a sensor array and a filter array for filtering the radiation depending on the wavelength, wherein, in order to reduce production costs, provision is made of a device for identifying the sensor pixels covered by the filter array, having a nonvolatile memory in which the coordinates of the filter array in relation to the sensor array and/or the coordinate transformation of the filter array in relation to the sensor array are/is stored in order to assign the sensor pixels to the individual filter pixels on the basis of the stored coordinates and/or coordinate transformation and/or in order to activate the individual filter pixels depending on which of the sensor pixels are covered by the corresponding filter pixels.
