Glass rods with partially-frosted surface

For different applications we produce glass rods with structured, partially fine-frosted surface. The rods are suitable for test mandrels for generating a passive backlight at the analysis of finely-structured metal fabric and tubes, as they are applicable in the medical technology. In the process can be used passively, as well as actively coupling illuminants.
