This certified standard enables precise calibration and validation of specular reflectance measurements at a 7 degree angle of incidence. Supplied with a NIST traceable certificate, it ensures compliance with rigorous quality requirements and supports reliable, reproducible analytical results. Primarily designed for use in materials science, optics, semiconductor analysis, and surface characterization laboratories, this standard is essential for routine instrument performance checks and method development involving reflective properties of substrates and thin films.

Researchers and QA professionals can confidently use this standard for calibrating benchtop and portable spectrophotometers, reflectometers, and ellipsometers operating at the specified angle. It is particularly well suited for validating reflectance measurements in applications such as optical coatings, photovoltaic materials, and advanced composites where precise optical assessment is needed.

This robust standard is compatible with a wide range of Agilent optical measurement instruments, as well as other leading brands that support external calibration standards and have fixtures for a 7 degree angle of incidence. Regular use of this product minimizes uncertainty and maximizes consistency in spectrophotometric analyses, ensuring high accuracy and traceability across multiple projects and compliance with regulatory or industry standards. Related products include additional NIST traceable reflectance and transmittance standards for broader calibration coverage.
