Description
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.
For measuring surfaces with low specular reflectivity, we recommend the STAN-SSL, which has ~4% reflectivity from 200-2500 nm. Add a STAN-HOLDER to keep your standards in place and to protect their coatings.
Specular reflectance – low specular reflectivity (4% reflectivity from 200-2500 nm)
Convenient holder – optional accessory holds standard in place
