(Gigahertz-Optik: Newburyport, MA) -- White optically diffuse reflecting material is useful in many lighting design, laser, and reflection and transmission applications, including integrating sphere coating, laser cavities, and reflectance standards.

Gigahertz-Optik’s white ODM98 optically diffuse material is a sintered polytetrafluoroethylene (PTFE), aka Teflon, and it works as a volume reflector. Besides exhibiting a nearly perfect diffuse reflectance of greater than 98 percent from 400–1600 nm and greater than 95 percent from 250–2000 nm, it features uniform reflectance across the ultraviolet (UV) to near-infrared (NIR) spectral range and over a large area. The ODM98 also features operating temperatures up to 200°C (300°C short exposures), long-term UV stability, high maximum permissible radiation flux densities, machinability, plus it can be cleaned and resurfaced.

Gigahertz-Optik now offers its new ODMP material in different grades of gray. It is made from ODM98, only the material is doped with different density black pigments. Gray scale material at different reflectance levels is required in many calibration tasks, such as qualifying the linearity of optical sensors.
