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.
