Maximizing UV-C Light Extraction Efficiency
Lithoglas® DUV-Caps
- High light output:
- High transparency for UV-C (fused silica)
- Al-coated reflector (55°)
- Anti-reflective coatings on lid
- Hermetic, inorganic materials,
- Bondable to substrate by metallization (Standard: Ni/Au)
- Heat transfer from lid to substrate through silicon sidewall
- Small outline, typical dimensions 3.4 mm x 3.4 mm x 1.2 mm
- Cap arrays with multiple reflectors for compact high power output
