| Accuflect (See the Accuflect section in Standard Products for more information including reflectance curves.) Accuflect
is a specially formulated and processed ceramic developed by Accuratus
to satisfy the market demand for diffuse reflectors in high temperature
and high energy environments. | .Key Property |  | Highly diffuse reflectance from near UV to Infrared | .
Typical Uses | | Flashlamp pumped solid state laser cavities | | Diode laser pumped solid state laser cavities | | High temperature diffuse illumination | | High temperature lamp housings | | Tube furnace radiant energy reflectors | General Information
B6 type Accuflect is a porous ceramic usable to 1300 °C. B6 material
has enhanced reflectance in the infrared. When the material is used in
water cooled cavities or areas of significant contamination a glazed
ceramic designated G6 is recommended. G6 is usable to 750 °C.
