Product Details

Ocean Insight offers specular reflectance standards for measuring shiny surfaces such as machined metals and semiconductor materials and low-reflectivity surfaces such as anti-reflective coatings and thin film coatings.

The STAN-SSH varies in reflectivity from 85%-98% over the 250-2500 nm wavelength range and is available in a version (STAN-SSH-NIST) calibrated to a NIST master standard. The NIST calibration data range is 250-2400 nm.

Product Overview

  • Specular reflectance – high specular reflectivity (85%-98% over the 250-2500 nm)
  • Calibrated standard – NIST-traceable version
  • Convenient holder – optional accessory holds standard in place
