Accuflect Material Characteristics

Specially formulated and processed reflecting ceramic for high temperature and high energy environments

Key Property
Lambertian behavior near UV to Infrared
 
Typical Reflector 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
Availability
Up to 76 mm diameter or square by 250 mm long
Types
B6-virgin porous ceramic surfaces recommended for dry, non-contaminating environments
G6-glazed ceramic surfaces recommended for wet or contaminating environments
Manufacture
Controlled particle and pore sizes and refractive index to maximize light scatter
Wide band gap binary and ternary metal oxides to minimize absorption UV to IR
No transition metal oxides to impair performance
