Optisches System mit großen Meßbereichen

摘要

The invention concerns an optical system for use in spectrometry and/or endoscopy, in which at least one probe is exposed to directional radiation produced by a radiation source, the radiation emanating from the probe is led to a spectrometer, in particular a simultaneous spectrometer, and or to an imaging device. It is proposed that the optical system should be provided with at least one control device with a radiation inlet surface and a radiation outlet surface; the control device should be provided with control elements (24) held by a frame and capable of being displaced from a first position in such a way that the radiation energy transferred from the radiation inlet surface to the radiation outlet surface can be controlled while leaving the radiation outlet aperture substantially unchanged. In addition, or alternatively, the optical system is provided with at least wavelength selection unit which has at least one dispersion element element for spectral splitting of the radiation passing through at least one inlet slit and impinging on the dispersion element; and with at least one optical waveguide. The dispersion element and/or a focusing element focus the spectrally split radiation onto a focal surface and the optical waveguide receives a predetermined range of the spectrally split radiation in the focal surface.
