Polyimide Coated Polyimide Coated Single-Mode Fiber is designed for optical sensor and datacom
systems where the fiber may experience extreme temperatures or be exposed to harsh
environments. The fiber has a nominal clad diameter of 125 μm and a polyimide coating
diameter of 155 μm. The fiber has been engineered such that the mode field diameter
accurately matches standard SMF for easy splicing.

Bend Insensitive bend insensitive fibers are designed for improved bend performance in reduced radius
applications. The fibers employ a moderately higher numerical aperture (NA) than
standard single-mode telecom fibers. The moderate NA delivers lower bend loss at 1550, 1310 and 780 nm without significantly affecting splicing performance. Higher numerical
aperture fibers are available upon request.

UV-VIS Single-Mode
NUV-320-K1 fiber is designed for single mode operation in the near ultra-violet region.
The single mode design makes this fiber ideal for an array of fiber optic probes used in a variety of UV-VIS spectroscopy applications such as color monitoring, film thickness,
chemical and nuclear processing, pharmaceuticals, emission monitoring and other
applications in the near UV spectrum.

Step Index Multi-Mode
This grade of fiber has a transmission range of 190 nm to 1.6 μm and is ideal for UV
microscopy, spectrophotometic studies and photochemical analysis applications.
