Temperature effect on liquid crystal refractive indices
A model describing the temperature effect of liquid crystal ~LC! refractive indices is derived and confirmed by experiment. Two single LC compounds ~5CB, 5PCH! and two mixtures ~MLC-6241-000 and UCF-35! with different birefringence values were used to validate the model. This model fits all the experimental data well. For a low-birefringence LC mixture, if the operating temperature is far below...
متن کاملInfrared refractive indices of liquid crystals
The refractive indices of E7 liquid-crystal mixture were measured at six visible and two infrared sl=1.55 and 10.6 mmd wavelengths at different temperatures, using Abbe and wedged cell refractometer methods, respectively. The experimental data of the visible wavelengths fit the extended Cauchy equations well. Using the extended Cauchy equations, we can extrapolate the refractive indices of E7 t...
متن کاملOn the Refractive Indices of Certain Proteins:
The change in the refractive indices of salt solutions which results from the addition of 1 per cent of the “pseudoglobulins” of blood serum has been measured by Reiss.l His pseudoglobulins were prepared by fractional precipitation with ammoniun sulphate and purified by prolonged dialysis. Fraction I (Pseudoglobulin I) was precipitated at 32-36 per cent saturation with ammonium sulphate, fracti...
متن کاملDensity and refractive indices of lactose solutions.
Lactose, the disacch arid e commonly known as milk sugar , has for many years been of commercial impor tance. U nt il r ecently i ts principal usc was in the manufacture of pharmaceu ticals, food products, and in th e preparation of modifi ed di ets; however, the penicillium industry now also r equires large quantiti es of this sugar. ! In th e presen t investigation measurements h ave been mad...
متن کاملBounds for the refractive indices of metamaterials
The set of realizable refractive indices as a function of frequency is considered. For passive media we give bounds for the refractive index variation in a finite bandwidth. Special attention is given to the loss and index variation in the case of left-handed materials.
