AirPhotonFounded in 2012 by scientists working in particulate measurement since the early 1990s, AirPhoton designs and manufactures field-deployable instruments for measuring airborne particulates and trace gases. The Maryland-based company, now part of GRASP Earth, pairs laboratory-level measurement capability with practical deployment in networks and missions including SPARTAN and NASA’s MAIA. Its instruments are built alongside scientific expertise in interpreting particulate and gas measurements, rather than sold as standalone hardware.BALTIMORE, MD
Spectra Vista CorporationSince 2003, Poughkeepsie-based Spectra Vista Corporation has built portable NIR spectroradiometers for researchers who need reliable spectral measurements in the field. Its i-Series instruments document each scan with GPS coordinates and a target photograph, while the company also maintains an optical laboratory for calibration and characterization of Spectra Vista and GER sensors. SVC continues to support legacy instruments through calibration and repair when components are available.POUGHKEEPSIE, NY
AccuStrata IncFounded in 2008 through the University of Maryland TAP program, Rockville-based AccuStrata develops custom optical spectroscopy instruments, sensors and control systems for real-time industrial and environmental monitoring. Its fiber-optic platforms combine optical measurement with predictive modeling and machine learning, while the company takes projects from early concepts through prototypes, field validation and commercialization. AccuStrata’s patented work includes AtOMS, a system for monitoring thin-film deposition and etching, and the company has developed technology for applications ranging from solar manufacturing to portable water testing.ROCKVILLE, MD
TelosAir, IncBased in Potsdam, TelosAir develops research-grade air-quality sensors and cloud analytics that make indoor and outdoor conditions visible in real time. Its system combines patent-pending sensing technology with the Insight Machine, which can diagnose building-air problems and connect with HVAC controls. TelosAir’s work has been tested by organizations including NASA, Ford, and Clarkson University, where a study reported 30–40% HVAC energy savings while maintaining healthy indoor air.POTSDAM, NY
