Product Details

The STS spectrometers for irradiance are radiometrically calibrated microspectrometers with a direct-attach cosine corrector. They have a rugged opto-mechanical design and great unit-to-unit reproducibility, making the STS attractive for integration into high-volume radiometric applications such as LED sorting on a production line.

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
  • Software – Oceanview Software is included
