Fery Grism prototype - Next Gen Atmospheric Gas Spectrometers & Solar Induced Fluorescence Imaging Spectrometers

Objectives for technology investment: • Demonstrate that JPL can electron-beam fabricate aberration- corrected gratings on curved odd-shaped fused-silica prisms. This will enable the SIF imaging spectrometer design, and will be a significant step towards the OCO-neXt silicon Fery grism. Key Technology development under this effort: • Fery grism prototype: E-beam fabrication of an aberration-corrected Fery grism for a SIF imaging spectrometer design. After fabrication, the grism will be characterized by profilometry and optically to the extent possible with simple setups. • TRL 2 to TRL 4

Increase scientific understanding of natural phenomena using remote sensing.

This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
