EQ-100
The continuous melting process can utilize raw materials with varying properties to produce transparent quartz tubes and rods of excellent appearance and dimensions, while thermal treatment allows adjustment of the OH content. It is suitable for manufacturing quartz components for electric light sources such as mercury lamps and halogen lamps, as well as for electrically heated outer tubes, semiconductor materials, and optical fiber preforms.

The continuous melting process can utilize raw materials with varying properties to produce transparent quartz tubes and rods of excellent appearance and dimensions, while thermal treatment allows adjustment of the OH content. It is suitable for manufacturing quartz components for electric light sources such as mercury lamps and halogen lamps, as well as for electrically heated outer tubes, semiconductor materials, and optical fiber preforms.
This method can also be used to produce milky quartz tubes (EQ‑U100 series), which are employed in infrared heating lamps and other applications.
