Product Details

The STS-NIR spectrometer (650-1100 nm) is a versatile choice for applications ranging from low-concentration absorbance measurements to high intensity laser characterization. Its rugged design, compact size and great unit-to-unit reproducibility make STS attractive for integration into other devices and setups where a small footprint is desired.

Product Overview

  • 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 more expensive setups
  • Reproducible – attractive design for integration and scalability
  • Multiple slit options -- STS-NIR models are available with 10 µm, 25 µm, 50 µm, 100 µm or 200 µm slits

Take advantage of our technical guidance and this interactive spectrometer range-resolution tool.
