Reflectance Standards

Reflectance Standards Ocean Optics offers specular and diffuse reflectance standards for measurements of various types of sample surfaces. Reflectance measurements are a ratio of the reflected light spectrum to the incident light spectrum. Since there is no way to directly collect all of the light incident on a surface, reflectivity is usually measured relative to a reference standard. To ensure best results, the standard selected should be similar in reflectivity to the sample to be measured.

Item Type Reflectance Material Key Feature
STAN-SSH Specular Al mirror on fused silica substrate High reflectivity standard
STAN-SSH-NIST Specular Al mirror on fused silica substrate NIST-traceable standard
STAN-SSL Specular Schott ND9 glass Low reflectivity standard
STAN-HOLDER Accessory NA Protects STAN-SSH units
WS-1 Diffuse PTFE >98% reflective from 250-1500 nm
WS-1-SL Diffuse Spectralon >99% reflective from 400-1500 nm

Additional Spectralon reflectance standards and targets are also available. Please contact an Applications Sales Engineer for assistance.
