Heat Dissipation Structure Ceramic Substrates

Sapphire Cells

Direct sapphire bonding technology makes hollow transparent cells a reality.

- The entire surface is covered with sapphire for superior
  chemical- and plasma-resistance to avoid acid and
  alkaline etching.
- Transparent body with a wide light transmission
  wavelength band
- Complex flow channels and joints are available
- Direct joining technology enables assembly with an
  optical prism
