The invention relates to electromagnetic radiation microoptical diffraction gratings and to a method suitable for the manufacture thereof. The diffraction gratings in accordance with the invention can be used as microspectrometers in the form of scanning microgratings. The microgratings are provided with a surface structure and are able to be manufactured cost effectively and in high volumes. The surface structure is formed at a surface of a substrate and is formed from linear structural elements arranged substantially equidistantly and aligned substantially parallel to one another. At least part of the surface of the substrate and of the structural elements is coated with at least one further layer which forms a uniform sinusoidal surface contoured in a wave-shape (sinusoidal) manner and having alternating arranged wave peaks and wave troughs. A reflective layer can additionally be applied to increase the intensity of reflected radiation.

The invention relates to an apparatus and to a method for controlling or regulating the deflection of micromechanically manufactured deflectable elements which, driven electrostatically, are deflected in an oscillating manner. It is the object of the invention to provide a possibility with which a much larger deflection range can be utilized and in so doing the required voltage potential difference for the electrostatic drive of a deflection can be kept small and the occurrence of the pull-in effect can be avoided. In accordance with the invention, a deflectable element is present which is held at a frame element by at least one spring element and which can be deflected using an electrostatic drive. The deflection can be achieved by means of at least one counter-electrode and the deflectable element usable as an electrode. In addition, at least one detector is present which is suitable for the contactless detection of at least one deflection position and which is connected to an electronic evaluation and control unit to influence the electrical voltage potential difference between the deflectable element and the counter-electrode(s) in dependence of a specific deflection position.

An optical device includes a deflectable optical functional structure for interacting with electromagnetic radiation incident thereon, and a protective structure which is associated to the optical functional structure and at least partly transparent for the electromagnetic radiation. The optical functional structure is arranged in a manner tilted relative to the protective structure so that, in a non-deflected position of the optical functional structure, a main beam path of the electromagnetic radiation which interacts with the optical functional structure through the protective structure has an angle relative to a sub-beam path of the electromagnetic radiation reflected at the protective structure.

The invention relates to active microoptic reflecting components for adapting or changing the focal length or focal position in optical systems. It is the object of the invention to make available a miniaturised reflecting microoptic component for focusing or defocusing incident electromagnetic radiation, with which a variation in the focal distance can be achieved simply and at low cost. On the component according to the invention there is an elastically deformably membrane which is formed at least with one reflecting layer comprising a first material or material mixture and at least with one further layer or substrate which is formed from a second material or material mixture. First and second materials or material mixtures have thermal coefficients of expansion which deviate from each other. In addition a heating or temperature control mechanism is present.
摘要:
The present invention is based on the knowledge that the advantages of a moveable dispersive element with regard to the simple detector element and the adjustability of the measurement range and the resolution can also be used in a miniaturization of a spectrometer, when the dispersive element is operated generally in resonance instead by a quasi-static drive. A proposed spectrometer comprises a vibratably suspended dispersive element for spectrally decomposing a light beam, whose spectral distribution is to be determined, into spectral components, a means for putting the vibratably suspended dispersive element into a vibration with a frequency, which is in such a ratio to the natural frequency of the vibratably suspended dispersive element that a resonance amplification of the voltage of the dispersive element occurs, and a detector for detecting a spectral component of the light beam.
