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.
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
