Abstract
An ordered chalcogenide fiber bundle with a high resolution for infrared imaging was fabricated using a stack-and-draw approach. The fiber bundle consisted of about 810,000 single fibers with an glass core of 9 μm in diameter and a polyetherimide (PEI) polymer cladding of 10 μm in diameter. The fibers showed good transparency in the 1.5–6.5 μm spectral region. It presented a resolution of and a crosstalk of . Fine thermal images of a hot soldering iron tip were delivered through the fiber bundle.
