Embodiment Construction

[0042] figure 1 A schematic diagram of a spectromicrometer module 100 according to one embodiment is shown. The microspectrometer module 100 includes: an optical resonator 102 for filtering light, such as a tunable Fabry-Perot interferometer; a detection device 104 for detecting light transmitted by the optical resonator 102; and a focusing element 106 , the focusing element is here exemplarily realized in the form of a lens 106 with a focal length f. Instead of such a lens 106 , the focusing element can also be realized as a focusing mirror. The detection device 104 is realized, for example, as a detector array having at least one first detection section 108 and at least one second detection element 110 . The detection device 104 is arranged at a distance corresponding to the focal length f from the lens 106 , wherein the lens 106 according to the exemplary embodiment is arranged between the optical resonator 102 and the detection device 104 . The lens 106 is designed to d...

Abstract

The invention relates to a microspectrometer module (100) consisting of an optical resonator (102) for filtering light, a detector device (104) for detecting light transmitted from the optical resonator (102), and a focusing element (106). The optical resonator (102) can be tuned with respect to a wavelength range to be filtered out. The detector device (104) has at least one first detector element (108) and at least one second detector element (110). The focusing element (106) is shaped so as to deflect a transmitted light beam bundle incident within a first angle of incidence range onto thefirst detector element (108) and a transmitted light beam bundle incident within a second angle of incidence range onto the second detector element (110).

Description

technical field [0001] The starting point of the invention is a device or a method according to the preambles of the independent claims. The subject of the invention is also a computer program. Background technique [0002] In US 20140320858 A1 a spectromicrometer is proposed which is based on an array of optical filters, lenses and detectors. Depending on the angle at which light hits the filter, different wavelength ranges are transmitted. Next, the light at different angles is imaged to different positions of the detector array by lenses respectively and a spectrum is thus obtained. Here, depending on the optical filter, only wavelength intervals of approximately 35 nm can be examined. In order to increase the wavelength range that can be inspected, it is necessary to use segmented optical filter elements, microlens arrays and detector arrays with high resolution. Here, however, light from different sections of the microlens array may overlap on the detector array, wh...
