20090091753 | THREE MIRROR ANASTIGMAT SPECTROGRAPH - A spectrograph including a primary mirror, a secondary mirror, and a tertiary mirror forming a TMA having a common vertex axis. The spectrograph also may include a collimating mirror, a diffraction grating, and a dispersive prism. The collimating mirror and an entrance aperture form an interchangeable module. Radiation received through the entrance aperture is reflected in a collimated pattern towards an aperture stop. The diffraction grating, located between the collimating mirror and prism, diffracts radiation passed through the aperture stop into multiple beams directed onto the prism. A flat mirror, located to one side of the vertex axis. receives and reflects the multiple beams exiting the prism onto the primary mirror, where they are reflected onto the secondary mirror. The secondary mirror reflects the beams to the tertiary mirror where they are reflected onto an image plane located on the other side of the vertex axis. | 04-09-2009 |
20090316146 | THREE MIRROR ANASTIGMAT SPECTROGRAPH - A portable spectrograph including a primary mirror, a secondary mirror, and a tertiary mirror forming a TMA having a common vertex axis, a diffraction grating, and a dispersive prism, where the portable spectrograph can detect wavelengths between 150 nm and 1.1 μm. The portable spectrograph also may include a collimating mirror and an entrance aperture, which form an interchangeable module. Radiation received through the entrance aperture is reflected in a collimated pattern towards an aperture stop. The diffraction grating, located between the collimating mirror and prism, diffracts radiation passed through the aperture stop into multiple beams directed onto the prism. A flat mirror, located to one side of the vertex axis receives and reflects the multiple beams exiting the prism onto the primary mirror, where they are reflected onto the secondary mirror.
