Abstract
An optical filter may include an interference filter that passes at least two channels associated with at least two transmission peaks; and a plurality of blockers, wherein each blocker, of the plurality of blockers, passes a respective channel associated with a respective transmission peak of the at least two transmission peaks and blocks one or more channels other than the respective channel associated with the respective transmission peak.
Claims20
An optical filter, comprising:
- an interference filter that passes at least two channels associated with at least two transmission peaks;
- and
- a plurality of blockers,
- wherein each blocker, of the plurality of blockers, is affixed to a same surface of the interference filter, passes a respective channel associated with a respective transmission peak of the at least two transmission peaks, and blocks one or more channels other than the respective channel associated with the respective transmission peak.
