The present invention concerns a process for contact-less temperature regulation, in which the temperature is measured in a contact-less mode with a temperature measurement device and detected as an analog value and then digitized, wherein moreover there is provided a digital regulator which outputs a control value in dependence on the detected temperature and predetermined regulating parameters and a corresponding apparatus. In order to provide a process and a corresponding apparatus for contact-less temperature regulation which can have extremely short response times and which at the same time have a relatively high degree of accuracy and parameterizability, it is proposed in accordance with the invention that the measurement data which are digitized by the electronic measurement system are processed in one and the same processor for the purposes of temperature determination and regulation, which is integrated into the electronic measurement system or the housing of the electronic measurement system, so that the raw data are used within the processor both for ascertaining the current temperature and also for calculating and producing a control value and thus the output of the electronic measurement system in the form of the regulator output directly supplies a control value for influencing the temperature to be regulated of an object.

The invention relates to a multispectral sensor with several filters and sensor elements for different spectral ranges of a radiation to be measured. The object of the invention is to so further develop a multispectral sensor of this type that it can be manufactured as a discrete component with small dimensions and has a high measuring accuracy, whilst obtaining a high output signal. This object is achieved in that the beam is broken down by an optical device into several partial beams and reflected onto filters. Behind the filters are located radiation-sensitive elements, which detect the spectral range corresponding to the transmission range of the in each case upstream filter. The remaining spectral range of the partial beam is reflected by the filter surface towards the other filters. Thus, each filter is supplied with the associated spectral ranges of all the partial beams.
