Deep ultraviolet optical fiberSpecifically referring to special quartz optical fibers that can stably transmit deep ultraviolet wavelengths, with low hydroxyl pure quartz as the core and fluorine doped quartz as the cladding, combined with sun drying technology and adaptive coating/buffer layers, widely used in spectral analysis, semiconductor detection, biosensing, and laser transmission scenarios.

　　Deep ultraviolet optical fiberSpecial fiber structures are usually used to reduce radiation loss and limited mode coupling effects, and improve transmission efficiency in the deep ultraviolet band. For example, using a step index distribution allows light to propagate through the core in a total reflection manner, reducing the loss of light energy. Meanwhile, by optimizing the geometric dimensions and numerical aperture of the optical fiber, its transmission performance can be further improved.

Usage and maintenance matters:

1. Environmental control: Maintain 15-30 ℃, low humidity, clean and dust-free, avoid chemical corrosion and severe vibration.

2. End face management: Use specialized cleaning paper and solvent to clean the end face, and regularly check the quality of the end face; Ensure that there are no impurities or scratches before installing the connector.

3. Power and pulse width control: do not exceed the fiber damage threshold, and a safety margin should be reserved for pulsed lasers; Avoid prolonged exposure to high power without load.

4. Bending and routing: Avoid excessively small bending radii to reduce bending losses and mechanical damage; Long distance transmission needs to consider the accumulation of losses and the number of joints.

5. Regular testing: Monitor insertion loss, transmittance, and power attenuation, and replace optical fibers or connectors in a timely manner when attenuation is abnormal.
