With polymer optical fibers (POF), both the fiber core and the cladding is manufactured from a polymer. Superior flexibility (high alternate bending loads with smaller bending radiuses), connection and transmission technology that is less expensive than silica-based systems, and simple assembly in the field are key advantages of polymer optical fibers.

The numerical aperture of the fibers can be changed by using other cladding materials. High-NA POFs, i.e. fibers with a higher increased numerical aperture, permit higher power coupling in the fiber. Increasing the NA results in a lower bandwidth, however.

The maximum application temperature for standard POF is limited to 85 °C by the cladding material. By using a different cladding material, thermal stability can be increased to 105 °C. However, this also increases the kilometric attenuation slightly. The PMMA core material is the limiting factor for even higher temperatures.

WEINERT Fiber Optics performs a 100% final inspection to verify optical attenuation on all POF cables in high-volume production. This enables us to guarantee first-class quality for our products. Measuring attenuation on complete cable drums (250 and 500 m) is a particular challenge, due to the high optical attenuation of the POF. WEINERT uses a measurement system specially developed for this purpose with an extremely high attenuation budget at 650 nm.

Close Focus Zoom Lenses are ideal for multipurpose applications that need both close focus and wide fields of view. The lenses offer variable apertures, to adjust the depth of field. Filter threading allows the use of filters to adjust incoming light levels with ND filters, or increase contrast with color filters on monochrome sensors, and more. Close Focus Zoom Lenses are economical and compact, and these lenses have many features that make them a perfect choice for a variety of uses. These zoom lenses feature 10X magnification and are compatible with C-mounts.
