Eljen Technology Introduces Plastic Fibers:
Designed for applications needing fiber optics and flexibility Eljen is announcing the introduction of our own brand of the plastic fiber optics. In ongoing collaboration with our clients and our extensive experience in the production of plastics we are embarking on bringing the best in plastic fiber optics to our customers. These new plastic fibers are based on the many years of producing the highest quality liquid and solid scintillators and wavelength shifters for the science and government communities.
The fibers will be available in single and double clad, round or square, canes, spools, and bundles, with diameters ranging from 0.3mm to 5.0mm. Furthermore, our cutting-edge fiber draw systems can create unclad for filament 3D printing of wavelength shifting and scintillating detector systems.
Eljen Technology’s scintillation plastic fibers can be supplied in plastic matrix bases of polyvinyl toluene (PVT) or polystyrene (PS). The fibers will be available in several formulations based on the standard Eljen Scintillation and Wavelength Shifting Plastics. All plastic scintillators are drawn and cut to customer specified dimensions and tested to meet specifications.
