New Product: Square Core Fiber

Unlike round core fiber, square core fiber produces well-defined edges and a homogenous beam output. These characteristics allow for smaller image overlap compared to round core fiber, ultimately providing increased efficiency for your application.

With the elimination of the overlapping step-and-repeat surface treatment, processes using the square core fiber see an improved return on investment (ROI) over the alternative of modifying existing circular core fiber processes.

In the life sciences, square core fibers are desirable due to their increased efficiency. They are especially effective for applications including microscopy, flow cytometry, DNA sequencing, and other bioanalytical instrumentation.

Fiberguide offers pure silica square core fibers with a fluorine doped cladding (0.22 NA) in a wide range of core diameters from 100 μm to 1000 μm.

This product is popularly used in conjunction with the Fiberguide De-Speckler and RARe Motheye anti-reflection technology.
