Keo Scientific designs and manufactures highly sensitive all-sky and narrow-field, wavelength resolved (multi-spectral) imagers for auroral studies. Several options are available: single-filter and filter-wheel based units, a variety of fields of views ranging from 2 degrees to 180 degrees (fish-eye), VIS, NIR and IR optimized imaging at speeds up to F0.7, onto a wide selection of different CCDs and Electron Multiplying CCDs (EMCCDs).

Photometers for Speace Weather / Auroral Studies

Keo Scientific designs and manufactures a wide range of highly sensitive photometers built around low-noise deep-cooled photomultiplier tubes (PMTs) as well as other more recent photon-counting sensor technologies. Leveraging almost 40 years of actual field experience, we go beyond textbook optics' knowledge and design photometers ideally suited to deal with the many non-obvious issues and problems associated with measuring the aurora borealis and australis. Single-filter, filter-wheel based, and multi-filter beam-split options are available for staring-mode as well as meridian-scanning operations.

Patrol Spectrograph for Space Weather / Auroral Studies

Keo Scientific has teamed up with Jeffrey Baumgardner and designed an innovative grism-based auroral spectrograph, providing continuous coverage of the 390–740 nm wavelength range simultaneously across the entire 180 degree meridian (in effect a solid-state meridian scanning photometer — no moving parts), in a very compact package. Single-photon sensitivity, and Quantum Efficiency of approximately 90% across the entire covered range.

Periscope Assemblies

Keo Scientific designs and manufactures articulated first-surface mirror assemblies (periscopes) with a variety of aperture sizes. Ideal for use with narrow field imagers, photometers and Fabry-Pérot Interferometers (FPIs), or as a Heliostat. For additional details go to our Keo SkyScan page.

Low Brightness Sources (LBS) and Calibration Services

Keo Scientific designs and builds portable low-brightness light-sources suitable for use in auroral and airglow research. We also provide full absolute spectral calibration and imager characterization services using our NIST traceable in-house integrating sphere, custom-built and calibrated especially for the extremely low light-levels encountered in atmospheric and ionospheric research.
