Zenith Lite™ Diffuse Reflectance Targets
Zenith Polymer® reflectance material provides the
highest diffuse reflectance of any known material
over the UV-VIS-NIR region. The reflectance is very
flat and generally > 99% over a range from 400 nm
to 1500 nm and > 95% from 250 nm to 2500 nm.
Surface or subsurface contamination may lower the
reflectance at the extreme upper and lower ends of
the spectral range.
The surface and the porous structure of Zenith
exhibits highly Lambertian behavior. The material
is extremely hydrophobic and shows no signs
of optical or physical degradation after long-term
immersion testing in fresh water.
