The Pure Silica Core PM Fiber (HB450-SC) is designed to address the needs of customers requiring Polarization Maintaining (PM) fibers capable of transmitting Ultra Violet (UV), violet, blue and green wavelengths without the photodarkening effects that impact standard

germanosilicate core fibers. The fiber is typically used in biomedical type applications, including confocal microscopy, DNA sequencing and flow cytometry and also has uses in environmental monitoring. The fiber is designed to be compatible with Fibercore’s Coreless End Cap Fiber (MM125), giving the customers the ability to expand the output beam of the fiber, reducing high power density end effects.
