VORRICHTUNG ZUR ABLENKUNG VON OPTISCHEN STRAHLEN
The invention relates to a device for the reflection of optical beams (25), provided with a piezo-plate (14), which has piezo-electric regions (15, 16), controlled by piezo electrodes (20, 21). At least one end section (22) of the piezo plate (14) is free of piezo electrodes (20, 21), whereby said f...

| Zusammenfassung: | The invention relates to a device for the reflection of optical beams (25), provided with a piezo-plate (14), which has piezo-electric regions (15, 16), controlled by piezo electrodes (20, 21). At least one end section (22) of the piezo plate (14) is free of piezo electrodes (20, 21), whereby said free end section (22) is of a size, corresponding to the dimensions of the beams falling thereon. A deflection is thus achieved which leaves the wavefronts of the beams (25) essentially undisturbed. |
