New Far Field Scanning Platform Provides Both Capability and Flexibility

Far field scanning is a useful tool for characterizing the mode field diameter (MFD) and effective area (Aeff)of single-mode fibers, as well as the numerical aperture of multimode fibers. It is also the reference measurement technique for all three measurements. Far field scanning is typically employed in lower volume laboratory or specialty fiber test applications where the slightly longer measurement time, relative to alternative test methods such as the variable aperture method, is more tolerable. It is also useful when comprehensive MFD/Aeff or NA measurement capability at wide range of wavelengths is required. Photon Kinetics’ new 2314 Far Field Scanner was designed specifically for these
types of testing applications.

The 2314, a new member of the Photon Kinetics PKSL instrument family, features a high-resolution radial scanner, plus integrated LED or laser light sources and buffer fibers in a compact package. A full range of standard and special LED and laser diode light sources are available including: 632, 780, 820, 850, 980, 1064, 1300, 1310, 1550 and 1625 nm. Optional 1120 Bare Fiber Aligner(s) can be employed with the 2314 to provide fast, low loss coupling of 125µm OD fibers to the light source buffer fibers.
