Literature Values of dn=dc obtained for NR and SR Solutions in THF …
WebSome typical refractive indices for yellow light (wavelength equal to 589 nanometres [10 −9 metre]) are the following: air, 1.0003; water, 1.333; crown glass, 1.517; dense flint glass, 1.655; and diamond, 2.417. The variation of refractive index with wavelength is the source of chromatic aberration in lenses. WebThe differential refractive index increment (dn/dc) value at 633 nm depends on the pair of sample and solvent; it is 0.130 ml/g for NR in THF [30].

The literature value for dn/dc of PLGA in tetrahydrofuran (THF) varies around 0.05 mL/g, but with no specific information on the PLGA used. We examined dn/dc values of various PLGAs having different ratios of lactide to glycolide (L:G ratios). cityark estate services
