The STS spectrometer is really small!

  • Compact – actual size is 40 x 42 x 24 mm
  • Powerful – high signal-to-noise (>1500:1) and dynamic range (4600:1) performance
  • Thermally stable – peak shape stays the same over a wide temperature range
  • Cost-effective – optical resolution of 1.5 nm is comparable to bench-top spectrometers
  • Reproducible – attractive design for OEM manufacturers
  • Plug-and-play – easy connectivity and adaptability with other devices

New! STS-UV-RAD  really low cost UV radiometer

STS-UV-RAD spectroradiometer - 190 - 650nm Spectrecology

The STS UV spectrometer is coupled to a  direct attach cosine corrector. The entire unit is calibrated to a NIST traceable D2 lamp to provide absolute irradiance (uW/cm2/nm) striking the plane of the cosine corrector. The unit couples to a PC by USB. Powerful Oceanview software runs the system, captures and displays irradiance spectra and also can display single value parameters such as integrated power or photon flux.

The STS is just as sensitive as our Flame, USB2000+ and HR spectrometers!

See our blog post with details!

STS spectrometers come in 3 wavelength ranges, UV, VIS and NIR.

They can be made with fixed slits (10, 25, 50, 100 or 200um).. Specifications for the 3 models are shown below.

STS spectrometer on drones!

Spectrecology is partnering with Advanced Airspace Management Systems to equip professional drones with advanced spectral and hyperspectral instrumentation.

We offer paired STS spectrometers for measuring solar reflectance. One unit measures downwelling sunlight, the other points at the ground and measures reflected upwelling light.  Applications include:

  • NDVI – normalized difference vegetation index – indicates presence of plants and is useful as a measure of health of plants
  • Spectral ID – recognizes spectral features to identify plants, invasive aquatic weeds, etc.

Our current project is identifying Egeria sp. (Brazilian water weed) in freshwater lakes.
