780 & 1060 nm Dispersion Controlled Select Cutoff Fibers
Coherent -OCT select cutoff single-mode fibers are optimized for Optical Coherence Tomography (OCT) medical imaging methods. These application-specific fibers were developed for next generation OCT applications that operate at both 780 and 1060nm and require exceptional uniformity, tight dispersion and core/clad concentricity control. The fibers are ideally suited for couplers used in OCT. This fiber can still be used for traditional applications as well and is prooftested to 200kpsi for superior strength. These -OCT fibers are part of the NuVIEWFA family of fibers providing extra high performance specifications for increased component reliability, component performance and production yields reducing component manufacturing costs. The -P version has a polyimide coating reducing overall fiber diameter and increasing operating temperature to 300°C.
