PH370 glass is a clear fused quartz available as tubing and rod.

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.
