Ondax Wins Multiline Filter Contract
To develop and produce multiline rejection filters, Ondax Inc. of Monrovia, Calif., has received a Phase 2 Small Business Innovation Research award from the National Science Foundation of Arlington, Va. Under the two-year, $500,000 contract, the company will develop fabrication technology for an astronomical holographic multispectral filter with up to 50 lines in the infrared region. The filter increases the signal-to-noise ratio of ground-based observations by suppressing the narrow lines emitted from atmospheric hydroxyl radicals. The project is expected to affect applications requiring fine multispectral feature extraction for accurate substance identification in remote sensing and the life sciences.
