Polarization-maintaining fibers are an essential component in advanced optical systems, designed to preserve the polarization state of light as it travels through the fiber. This unique capability is achieved through the integration of stress elements embedded within the fiber's cladding, which induce birefringence in the fiber core. The result is a fiber that can maintain the polarization of light, making it invaluable in precision applications where signal integrity is paramount. The design of these stress elements can vary, offering flexibility in tailoring the fibers for specific needs. Whether utilized in optical networks, pump lasers, or microscopic applications, these fibers provide the reliability and performance necessary for cutting-edge technologies. The fibers are available in various configurations, including the widely recognized Panda and Bow Tie types, each offering distinct advantages depending on the application requirements. 

Polarization-maintaining fibers are engineered to perform across a broad range of wavelengths, from the visible spectrum (VIS) to the infrared (IR). This versatility ensures that they can be effectively integrated into a wide array of optical systems. With mode field diameters tailored for specific wavelengths and jacket diameters standardized at 125 µm, these fibers are designed for compatibility and ease of integration. The fibers exhibit exceptional transmission properties, with specific attenuation rates and cut-off wavelengths optimized for different spectral ranges. This ensures minimal signal loss and high fidelity in data transmission, critical for applications demanding precision and accuracy. The numerical aperture of these fibers is carefully calibrated to balance light-gathering ability and resolution, enhancing their performance in diverse environments. 

Manufactured with a silica core and acrylate coating, these fibers offer durability and protection against environmental factors. The standard coating diameter is 245 µm, with some variations available to meet specific application needs. For projects requiring additional customization, jacketings and assemblies can be tailored upon request, providing solutions that meet the exacting standards of your optical system. Each fiber type, whether Panda or Bow Tie, is meticulously crafted to deliver optimal performance. With a comprehensive range of order numbers available, selecting the right fiber for your application is straightforward. These polarization-maintaining fibers are a testament to innovation in optical technology, offering the precision and reliability required for today's most demanding applications.
