Astronomy, Space & Remote Sensing

Astronomy spectroscopy gives researchers a way to study light from objects and environments far beyond the laboratory. StellarNet systems support astronomical spectroscopy for research into stars, planets, meteors, and atmospheric phenomena. Spectral measurements can reveal information that cannot be seen through imaging alone. Compact instruments also open new possibilities for space spectroscopy and CubeSat missions where size and flexibility matter. From meteor and aurora research to remote sensing and educational astronomy, StellarNet provides accessible spectroscopy tools for exploring our planet and the universe beyond it.

MISSE (Materials International Space Station Experiment), a joint project between NASA and Boeing

Our BLUE-Wave spectrometers were launched into space and mounted on the ISS as part of the MISSE-7 experiment, designed to take real-time spectra to provide insight on how the environment of space affects different optical properties of materials. Many of the materials were designed for space exposure and are considered next generation materials for space travel.

UV-VIS Spectrometers

From miniature USB spectrometers for OEM integration to high-performance StellarElite™ systems for demanding analytical measurements, StellarNet offers flexible UV-VIS spectrometer solutions with configurable wavelength ranges, optical resolutions, detector technologies, software platforms, and sampling accessories. Explore our UV-VIS spectrometer lineup below to compare performance, optical configurations, and system capabilities for your specific spectroscopy requirements.

NIR Spectrometers

StellarNet NIR spectrometers provide laboratory-quality performance in compact, rugged systems designed for research, quality control, process monitoring, OEM integration, and field applications. Available in wavelength ranges from 900–1700 nm through extended-range systems covering 200–2300 nm, our instruments support absorbance, reflectance, transmission, and diffuse reflectance measurements for both laboratory and production environments.

Raman Spectrometers

Raman spectrometers provide rapid, non-destructive chemical identification and molecular characterization for research, quality control, process monitoring, and material verification applications. By measuring the unique Raman spectrum generated when laser light interacts with a sample, Raman spectroscopy enables identification of unknown materials, verification of raw ingredients, detection of contaminants, and analysis of chemical composition with little or no sample preparation.
