高平面度窗片
Our BK7 or Fused Silica windows are available with improved surface quality and parallelism. Furthermore, these windows will limit the transmitted wavefront distortion to 1/10 wave. BK7 windows are used for visible and near IR. Fused Silica windows are not only used for UV but also used as heat-resistant windows in 800°C.The superior transmission characteristics and excellent thermal properties combined with high tolerance manufacturing specifications make these windows a suitable choice for more demanding applications.
