摘要:
In plasma deposition processes for producing an optical preform according to the POD method, a cladding glass layer composed of fluorine-doped quartz glass is produced by means of a plasma torch on a cylindrical substrate body composed of quartz glass, said substrate body rotating about the longitudinal axis thereof. In this case, the plasma torch performs a reversing relative movement between two turning points (A; B) along the substrate body. In order, proceeding therefrom, to achieve a high fluorine doping in conjunction with a dopant distribution that is as uniform as possible axially, the invention proposes that a heat element has a heating effect on the region of one turning point (A; B) when the plasma torch is situated in the region of the other turning point (B; A).
摘要(中):
在根据POD方法制造光学预成型件的等离子体沉积工艺中,由掺杂氟石英玻璃构成的包层玻璃层通过等离子体焰炬在由石英玻璃构成的圆筒形基板主体上产生,所述基板主体围绕 纵轴。 在这种情况下,等离子体焰炬沿着基板主体在两个转折点(A; B)之间执行反转相对运动。 为了顺利进行,为了实现与掺杂剂分布结合,尽可能均匀的氟掺杂,本发明提出,热元件对于一个转折点(A; B)的区域具有加热效应,当 等离子体焰炬位于另一转折点(B; A)的区域。
