Abstract: An optical spectrometer arrangement is provided. According to an example, the optical spectrometer arrangement includes a linear array detector for receiving light at a predefined range of wavelengths, a point detector for receiving light at a predefined wavelength that is outside said predefined range of wavelengths, and an arrangement of a collimating optical element, a diffracting optical element, and a focusing optical element that are arranged to provide at least a first optical path that guides incoming light at said predefined range of wavelengths to the linear array detector via the collimating optical element, the diffracting optical element and the focusing optical element, and a second optical path that guides incoming light at said predefined wavelength to the point detector via the collimating optical element, the diffracting optical element and one of the collimating optical element and the focusing optical element.
