Hollow Waveguide Silica fibers
The hollow waveguide fiber (HWG)...
is a flexible and multidisciplinary laser tool for the transmission of radiation in the mid-infrared range (2-18mic) for minimally invasive procedures such as ENT, gynecology, and dermatology with CO2 and Er:YAG lasers.
Due to their flexibility and small diameter, hollow waveguide fibers can be used in areas that are not accessible for laser systems with mirror articulated arm technology.
Features:
- High transmission
- Inner diameter 500-1000 mic
- Double polymer coating for high flexibility
- Biocompatible materials
- Customized connector design, available
- Validated sterilization Process
