Item Code: STS-VIS

The STS-VIS spectrometer delivers the performance you need, whether you are performing low-concentration absorbance measurements or high intensity laser characterization. It covers the range of 350-800 nm. Its rugged design and great unit-to-unit reproducibility make STS attractive for integration into devices or applications where a small footprint is required.

  • 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

Measurement Techniques in which this product is used:

The relative response of STS model spectrometers shows the relationship between grating efficiency and wavelength range. Our setups used each spectrometer with a deuterium-tungsten halogen source and 600 µm SR fiber. The data was taken in Scope Mode (raw data) and normalized.
