aAt a sufficiently high power level, local defects are created within the core, which then gives rise to a periodic change in the local refractive index (RI). 在一个充足地威力强大的水平,地方瑕疵在核心之内被创造,然后提升在地方折射率RI上的一个周期性 (变化)。[translate]...
To avoid light losses the ring is formed of a material having a lower refractive index than the glass and is fitted on to the fibre end which has previously been stripped of the coating for the required length. Where the fibre is silica glass, the ring is pref. formed of lithium ...
The invention relates to an ophthalmic lens of uniform power at which the variable refractive index gradient present a different of revolution with respect to the optical axis. The lens, according to the invention, is characterized in that the shape of curvature of at least one of the two surf...
More specifically, the reproduction is conducted through detection of any change in the spectral reflectance, transmissivity, polarization or refractive index for the laser beam applied to the optical disc. The change in the reflectance and polarization, as well as the refractive index, is measured ...
(57)< Abstract > This invention regards the polymerization characteristic composition which possesses high refractive index and high Abbe number. The aforementioned composition which consists of polymerization characteristic monomer (A) at least the poly- thio (meta) acrylate monomer of 1; (B) at lea...
