Glass Capillaries

Optical glass capillaries are precision-engineered, thin-walled tubes made from optical-grade glass, designed for applications requiring the transmission, manipulation, or observation of light through the capillary walls. These specialized capillaries are crafted to maintain high clarity, ensure minimal optical distortion, and offer superior light transmission properties. They find extensive use in fields such as microscopy, where they facilitate the observation of microscopic samples with high resolution; in fiber optics, serving as preforms for drawing fibers; and in spectroscopy, for holding liquid samples for light absorption and transmission studies. The choice of glass material—such as borosilicate, fused silica, or quartz—depends on the specific optical properties required, including UV transparency, thermal stability, and resistance to chemical attack.

Optical glass capillaries are utilized in a diverse range of scientific and technological applications due to their unique properties. In microscopy, they enable high-resolution imaging of samples by serving as microfluidic channels, allowing for precise manipulation and observation of biological specimens. In the field of fiber optics, these capillaries act as preforms for drawing optical fibers used in telecommunications, offering a pathway for light signals over long distances. Additionally, in spectroscopy, optical glass capillaries are employed to hold small volumes of liquid samples for analysis, facilitating accurate measurements of light absorption and transmission. Their ability to maintain clarity and ensure minimal optical distortion makes them indispensable in research and industry for applications requiring precise optical performance.
