ILT2400 Handheld Light Meter and Optometer Series

Multi Mode, Step Index; 650 nm; Core Diameter 240-2,980 µm; Cladding Diameter 250-3,000 µm; Coating PE, PVC, Polyamide, PP, None; Numerical Aperture 0.46-0.58 Toray Industries' plastic optical fiber products, RAYTELA™, boast highly reliable transmission with low attenuation and excellent noise-resistant characteristics. RAYTELA is a multi mode, step index optical fiber with low loss and high reliability. Compared to optical fibers with cores made of silica or composite glass, plastic optical fibers (POF) are entirely made of polymer materials. Not only coatings and jackets, but also fiber core and cladding consist of polymers. While showing higher attenuation and lower transmission capacity, plastic optical fibers are less brittle, lightweight, more flexible, easier to handle and very cost-effective. The polymethyl methacrylate (PMMA) that makes up the core portion of the RAYTELA fiber uses a clean polymer made with integrated manufacturing from monomer through to fiber production. A special fluorine containing polymer is used for the cladding. Plastic optical fiber cords, curl cords or cables with PE, PVC, or PP jacket are also available. The cable diameter ranges between 5 and 6 mm. These lines have good resistance to heat, physical determination and chemicals. Furthermore, light guides with up to 64 fibers, bundled and jacketed for a temperature range up to +105°C are available. They are suitable for light sources of medical devices and display lighting for art objects among others. The portfolio comprises also plastic optical fiber cords for broadband communications and high NA fibers.
