WebThe first order retardation plate is a standard accessory that is frequently utilized to determine the optical sign (positive or negative) of a birefringent specimen in polarized light microscopy. In addition, the retardation plate is also useful for enhancing contrast in weakly birefringent specimens. WebApr 10, 2024 · The nonlinear optical properties of broad range of nonlinear optical (NLO) materials have been the subject of extensive research over the last few decades [].NLO materials with quick response time, large nonlinear refractive index and third-order optical susceptibility are very much essential for applications in high-speed optical …
