Abstract
A spectrometer that includes: a first diffraction grating configured to spectroscopically process provided light; a first detection unit configured to condense light spectroscopically processed by the first diffraction grating and to output an electrical signal corresponding to condensed light; a second diffraction grating configured to spectroscopically process 0th order light provided by the first diffraction grating; and a second detection unit configured to condense light spectroscopically processed by the second diffraction grating and to output an electrical signal corresponding to condensed light.
Claims28
A spectrometer comprising:
- a first diffraction grating configured to spectroscopically process provided light;
- a first detection device configured to condense light spectroscopically processed by the first diffraction grating and to output an electrical signal corresponding to condensed light;
- a second diffraction grating configured to spectroscopically process 0th order light provided by the first diffraction grating;
- and
- a second detection device configured to condense light spectroscopically processed by the second diffraction grating and to output an electrical signal corresponding to condensed light,
- wherein the spectrometer is configured to allow a position of the first detection device to be adjusted with respect to the first diffraction grating such that a light of a predetermined order provided by the first diffraction grating is provided to the first detection device.
A spectrometer comprising:
- a diffraction grating configured to spectroscopically process provided light;
- a first detection device configured to condense light spectroscopically processed by the diffraction grating and to output an electrical signal corresponding to condensed light;
- a reflection mirror configured to reflect 0th order light output from the diffraction grating back to the diffraction grating;
- and
- a second detection device,
- wherein the diffraction grating is configured to spectroscopically process the 0th order light reflected by the reflection mirror and to provide spectroscopically processed light to the second detection device,
- wherein the spectrometer is configured to allow at least any one of a position, of the first detection device, and a position, of the second detection device, to be adjusted with respect to the diffraction grating such that a light of a predetermined order provided by the first diffraction grating is provided to the first detection device.
An imaging device comprising:
- a diffraction grating configured to spectroscopically process provided light;
- a detection device configured to condense light spectroscopically processed by the diffraction grating and to output condensed light in an electrical signal;
- and
- an imaging unit configured to image 0th order light output from the diffraction grating, wherein the imaging unit comprises a focusing lens configured to focus the 0th order light,
- wherein the imaging device is configured to allow a position of the detection device to be adjusted with respect to the diffraction grating such that a light of a predetermined order provided by the diffraction grating is provided to the detection device.
