As a result, mass production is difficult to implement due to at least high costs and the mechanical stability and possibly necessary geometric expansion can prevent locations and purposes.

- This sensor is designed for a specific analytic that has to interact with the sensor. Then, for example, the spectral shift of a resonance or a change in intensity is measured. It is disadvantageous that a certain time t (a few seconds to a few minutes) is necessary for this process until an equilibrium state is established, both during the detection of the analytic and during the subsequent reactivation of the sensor. In addition, it is not apparent in what form a broad spectrum of light is analyzed by the sensor.

- the advantages of the monolithic device 1 according to the invention and of the spectrometric device 100 containing the monolithic device 1 are as follows:
- the direct connection of the detector / photodiode 30 and the spectrally resolving element 20 - of the filter - precludes adjustment of the essential device components 30, 20. Furthermore, there is no need for a spectral calibration of the device 1.
- the advantageously small extent and the simple possibility of encapsulating the photodiode 30 on / in the filter 20 allow it to be used in confined and stressed environments.
- the structure of the monolithic device 1 of filter 20 and detector 30 of the present invention can be fabricated as a complete unit in one process (e.g., PVD methods for filter and detector layers), thereby providing a very low cost sensor.
- a further advantage is that, as shown in Fig. 1, the detector / photodiode 30 is placed behind the high-Q filter (Q-factor) of the link to achieve a high spectral resolution of the input signal 11, 13 , LIST OF REFERENCE NUMBERS
