Fiber performance is a decisive factor in the precision and safety of minimally invasive surgery, diagnostic imaging and laser therapy. A portfolio of medical fiber solutions is designed to address diagnostic sensing, laser power delivery and precision imaging requirements while accommodating the packaging and integration constraints faced by medical device manufacturers.
Medical sensing fibers for minimally invasive procedures
The medical sensing fiber range is developed for advanced medical equipment and supports multimode and single-mode configurations. It is used in diagnostic, visualization and tissue ablation procedures, including non-invasive and minimally invasive surgical scenarios.
-
Miniaturized design:
Smaller outer diameters are available for minimally invasive interventional devices, supporting compact packaging requirements.
-
Bend performance:
A high numerical aperture design is intended to maintain low bend loss at very small bend radii, accommodating complex surgical routing.
-
Customization:
Refractive index profiles and cladding diameters can be tailored to match device integration needs.
These characteristics are relevant where tight bends and limited space constrain the optical path, such as in catheter-based diagnostic and therapeutic instruments.
Laser delivery fibers for high power and reliability
Laser surgery places stringent demands on energy delivery. Two high-performance pure silica core fiber series are designed to support stable power transmission and biocompatibility during procedures.

Reliability requirements in medical device development
In medical device development, material reliability is a primary consideration. The fibers are specified not only for basic transmission performance but also for biocompatible design and production standards intended to support stable operation in sensitive environments such as operating rooms.
Applications range from low-loss imaging links to laser delivery under high temperature and high power conditions. In each case, the fiber specification is matched to the optical, thermal and mechanical requirements of the instrument.
Frequently Asked Questions
Can medical fiber coatings withstand high-temperature sterilization?
The NIR series uses a polyimide coating and supports operating environments up to 300°C, which is intended to accommodate conventional high-temperature medical sterilization. Sterilization process parameters should be checked against the fiber tolerance range during selection.
How should high-OH or low-OH fiber be selected for surgical needs?
Energy delivery in the UV-Vis range generally requires a high-OH pure silica core fiber to maintain spectral transmission. For near-infrared laser power delivery, low-OH fiber can reduce energy absorption loss. Selection should be matched to the laser wavelength and application.
What effect does core diameter have on minimally invasive devices?
A larger core, such as 2,000 μm, is suited to high-power laser delivery, while a smaller core, such as 50 μm, is better for space-constrained minimally invasive interventional devices. Selection requires balancing laser power density against device integration space.
