780-OCT Optical Fiber

The corneal reshaping laser scanning system is a core optical module for femtosecond-laser-assisted corneal refractive procedures (LASIK and SMILE). It precisely focuses femtosecond pulses at a specified depth in the corneal stroma, using point-by-point scanning to form a lenticule that is separated and removed to change corneal curvature and correct refractive errors. Shzzcs provides a complete optical-path design, including beam expansion and collimation, high-speed scanning-galvanometer control optics, a focusing objective and real-time confocal monitoring. Key features include a focal-spot diameter <2μm and micrometer-level positioning accuracy; scanning across a φ10mm corneal region for different correction requirements; and real-time OCT navigation optics to monitor cutting depth and position throughout the procedure to ensure surgical safety. Lens groups are specifically optimized for chromatic and other aberrations at different laser wavelengths (1030nm/1045nm), concentrating focal energy without side-lobe damage. The system is used in refractive surgery equipment, corneal transplantation instruments and ophthalmic research platforms for precise, minimally invasive and personalized corneal reshaping.

Operating Wavelength: 930-1550 nm Core Numerical Aperture: 0.140 Mode Field Diameter MFD (Gaussian) [@980nm]: 6.0 ± 0.3 @ 980nm

Coherent/Nufern OCT series select-cutoff single-mode fibers are specialty fibers optimized for optical coherence tomography (OCT) medical imaging. They meet application-specific needs for next-generation OCT, including operation at 780nm and 1060nm. The series requires exceptional consistency and strict control of dispersion and core/cladding concentricity. These fibers are ideal for couplers in OCT systems and are also suitable for conventional applications. Proof-test levels above 200kpsi provide improved strength. As members of the NuVIEW family, their additional high-performance specifications improve device reliability, while strict performance specifications help manufacturers increase yield and reduce costs. OCT-P fibers have polyimide coatings and a small outside diameter and are suitable for temperatures of 300 degrees.
