Abstract
An optical arrangement for at least partial spectral selection of light components from a polychromatic light beam (1) is configured, in the interest of multifarious spectral selection capabilities, with means of simple design in such a way that a dispersive medium (2) for spatial spectral spreading of the polychromatic light beam (1) into individual light bundles (3), and an attenuation means (5, 6) for at least partial attenuation of the intensity of one or more light bundles (3), are provided.
Claims35
An optical arrangement for at least partial spectral selection of light components from a polychromatic light beam comprising a dispersive medium for spatial spectral spreading of the polychromatic light beam defining a plurality of individual light bundles, and an attenuation means for at least partial attenuation of the intensity of one or more of said light bundles, said dispersive medium comprising a prism adapted to disperse the polychromatic light beam and be mechanically movable for selecting a light bundle for coupling to the attenuation means.
An optical arrangement for at least partial spectral selection of light components from a polychromatic light beam, comprising a dispersive medium for spatial spectral spreading of the polychromatic light beam wherein the dispersive medium is a four-prism arrangement defining a plurality of individual light bundles, and an attenuation means for at least partial attenuation of the intensity of one or more of said light bundles.
An optical arrangement for at least partial spectral selection of light components from a polychromatic light beam, comprising a dispersive medium for spatial spectral spreading of the polychromatic light beam to define a plurality of individual light bundles, the dispersive medium configured as a parallelepipedal glass member with two parallelogram-shaped side surfaces, and an attenuation means for at least partial attenuation of the intensity of one or more of said light bundles.
