The specific properties are:
- A high transmittance in the Visible Region (400-750 nm) for maximum light output; the typical transmittance is 93%.
- A very low -OH content (down to < 0.5 ppm) for long lamp lifetime.
- A very low Alkali level for long lamp lifetime.
- Extreme tight dimensional tolerances for excellent bulb shaping.
Main application area is:
Discharge Tubes for Ultra High Pressure Projection Lamps.
