IdealPhotonics are optimized in the core parameters and waveguide stracture on the basis of ordinary single mode fibre. It takes advantage of PCVD process to realize operating wavelength of single-mode transmission. Idealphotonics’s High consistency and extreme end-to-end control of optical properties provide particular advantage in spectrographic and frequency sensitive applications. The pure silica core fiber is optimum for demanding applications in the UV and visible spectrum requiring ultra-low attenuation over longer lengths and where resistance to radiation-induced damage and color center formation are critical.
