Development of a wide‑band imaging FT‑IR using wavefront‑division interferometry for future planetary and space‑exploration payloads

We developed a compact imaging Fourier transform infrared (FT-IR) spectrometer based on wavefront-division interferometry for planetary exploration and small-satellite missions. The instrument covers 4–20 μm with a wavenumber resolution of 3.8 cm−1 and a spatial resolution of 34 μm. The optical system uses two Zernike...

Development and ground-based demonstration of a CdZnTe immersion grating for space-based mid-infrared high-resolution spectroscopy

High-resolution spectroscopy of molecular lines in the mid-infrared fingerprint region allows innovative science cases, such as surveying snowline locations in protoplanetary disks, but poor atmospheric transmission in this range hinders sensitive, continuous ground-based observations. We are proposing the High-Resolut...
