Ball-Tip Quartz Fiber QT-04
Ball-tip silica fiber is a special optical fiber with a spherical tip at one end. This design concentrates light emitted from, or collected into, the fiber end face. Ball-tip silica fibers are generally used for precise optical measurements and efficient optical-signal coupling. Silica offers excellent optical transparency and low optical loss, so these fibers are widely used in communications, medicine, and scientific research. Their manufacture involves precision processing. High-purity silica glass is first prepared and drawn into fiber. Specific heating and shaping methods, such as CO2 laser heating, then melt one end face into a spherical structure. Heating temperature and duration must be precisely controlled to meet the required tip shape and size. Main characteristics include low loss, high transmission efficiency, and good optical performance. Silica itself has a relatively low refractive index and damage threshold, allowing low-loss signal transmission over a broad wavelength range. The spherical tip further optimizes coupling efficiency and concentrates transmitted light, which is critical to overall fiber-system performance. Because of their distinctive structure and excellent optical performance, ball-tip silica fibers are widely used in multiple fields. In communication systems they can improve signal transmission efficiency and quality. In medicine they support precise optical imaging and laser surgery. They are also commonly used for optical measurement and precise signal control in research experiments.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
