DETAILS
1940nm Thulium fiber laser filter
The wavelength of thulium fiber laser is 1940nm, which is located at the peak of water absorption and has high vaporization cutting efficiency.
The 1940nm wavelength has a shallow penetration depth in the tissue, only 0.1-0.2mm, and tissue cutting is more precise.
