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 1100 °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.
