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.
Claims37
An optical arrangement for at least partial spectral selection of light components from a polychromatic light beam (1), comprising a dispersive medium for spatial spectral spreading of the polychromatic light beam (1) and thereby defining a plurality of individual light bundles (3;
- 20-23;
- 26-29), and an attenuation means (5, 6;
- 9, 12;
- 40-45;
- 53-56) for at least partial attenuation of the intensity of one or more light bundles (3;
- 20-23;
- 26-29).
The optical arrangement as defined in claim 10, characterized in that the attenuation means has a monomode glass fiber (6).
An optical arrangement for at least partial spectral selection of light components from a polychromatic light beam (1), comprising a dispersive medium for spatial spectral spreading of the polychromatic light beam (1) wherein the dispersive medium is a four-prism arrangement, the dispersive medium defines a plurality of individual light bundles (20-23), and an attenuation means (9, 12) for at least partial attenuation of the intensity of one or more light bundles (20-23).
An optical arrangement for at least partial spectral selection of light components from a polychromatic light beam (1), comprising a dispersive medium for spatial spectral spreading of the polychromatic light beam (1) and thereby defining a plurality of individual light bundles (26-29), the dispersive medium is configured as a parallelepipedal glass member (24;
- 38;
- 48) with two parallelogram-shaped side surfaces and an attenuation means (9, 12;
- 40-45;
- 53-56) for at least partial attenuation of the intensity of one or more light bundles (26-29).
An optical arrangement for at least partial spectral selection of light components from a polychromatic light beam (1), comprising a dispersive medium for spatial spectral spreading of the polychromatic light beam (1) and thereby defining a plurality of individual light bundles (26-29), the dispersive medium is configured as a parallelepipedal glass member (38;
- 48) with two parallelogram-shaped side surfaces, an attenuation means (9, 12;
- 40-45;
- 53-56) for at least partial attenuation of the intensity of one or more light bundles (26-29) and a reflection device for the at least one light bundle is arranged after the attenuation means.
