Description
The National Aeronautics and Space Administration project aims to fabricate silicon immersion gratings for infrared spectroscopy across 1150 to 6500 nm wavelengths. These devices are designed to support ground-based, airborne, and space-based spectrometers, offering a 3.44 times improvement in resolving power over conventional front-surface gratings of the same size. The dataset was last updated on March 13, 2026.
Use Cases
Benchmarking the performance of compact dispersive devices based on the described 3.44x resolving power advantage.
Designing infrared spectrometer architectures for ground, airborne, or space-based platforms based on the specified wavelength range.
Researching material and fabrication techniques for silicon immersion gratings based on the project's stated development goals.
Strengths
Project is associated with the National Aeronautics and Space Administration.
The description provides a specific performance metric: 3.44 times the resolving power of a conventional device.
The target infrared wavelength range is explicitly defined as 1150 to 6500 nm.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
The description metadata is limited; actual data quality requires manual inspection after download.
