Specular Reflectance Standard, low reflectivity

$537.00

Description

The STAN-SSL Low-reflectivity Specular Reflectance Standard is a black glass standard that can be used as a  reference when measuring surfaces with low specular reflectance values such as thin film coatings, anti-reflective coatings, blocking filters and substrates. The coated surface of the STAN-SSL provides an ~4.0% reflectance across the  200-2500 nm wavelength range
