Spectralon reflectance material is characterized by a high reflectance and lambertian 
behavior over the UV-VIS-NIR wavelength region. The reflectance of Spectralon 
is >99% over the wavelength range from 400 to 1500 nm, and >95% over the 
wavelength range from 250 to 2500 nm. This wide range of high reflectance allows 
for the material to be used from the UV into the NIR region of the spectrum. The 
material is ideal for fabrication of components such as integrating spheres, lamp 
housings, backlight panels, line illuminators and panel reflectors.  Optical-grade Spectralon 
is hydrophobic and thermally stable to 350°C. It is chemically inert to all but 
the most powerful bases such as sodium amide and organo-sodium of lithium compounds. 
The material is durable and maintains consistent reflectance even under harsh 
laboratory or field conditions. The use of optical-grade Spectralon assures the 
user of highly accurate, reproducible spectral data when used in the construction 
of optical components.

 Spectralon diffusion 
material consists of thin sections, generally between 0.1 and 1.0 mm, of specially 
formulated Spectralon designed to transmit and efficiently scatter incident light. 
Diffusers fabricated from Spectralon are particularly useful for broad-band diffusion 
of optical radiation, from the UV spectral region to the NIR spectral region. 
Spectralon diffusion material is invaluable in reducing the sensitivity of detectors 
to beam alignment and improving the uniformity of light sources. 
 These diffusers have 
a useful range of 200-2500 nm, and are significantly more diffuse than double-ground 
quartz.
