Ocean Optics STS-VIS microspectometer - micro spectrophotometer

Condition: new (never used, manufacture packaging)

Weight: less than 2 ounces (~ 50 g)

Size: 40 x 42 x 24 mm


STS spectrometers weigh less than 2 ounces, and measure a mere 40 x 42 x 24 mm. You get a remarkable amount of performance into this tiny footprint, with high signal to noise ratio, high dynamic range, and low stray light.  With resolution of ~1.5 nm (FWHM) in three spectral ranges, it is a compact, high-performance choice for a wide range of moderate to high-intensity applications.


  • 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 benchtop spectrometers
  • Reproducible – attractive design for OEM manufacturers
  • Plug-and-play – easy connectivity and adaptability with other devices
