Abstract
Preferential optical splitters are used in a multichannel wavelength measurement device. The optical splitters preferentially provide light at a certain wavelength to a detector. Preferentially providing light to the detectors allows for increased optical efficiencies.
Claims18
A multichannel wavelength measurement device comprising:
- multiple optical detectors, each detector adapted to detect light at a different wavelength;
- and
- a sequence of optical wavelength splitters in an optical path, each of the optical splitters adapted to preferentially provide light to one of the detectors at the desired detected wavelength of the detector.
A method comprising:
- using optical splitters to preferentially provide light from an optical path to detectors at desired detected wavelengths of the detector;
- and
- using the detectors to detect light at the desired detected wavelength.
