Optical constants (refractive index and extinction coefficient, n k) of (C H O ) n (Polycarbonate, PC): Sultanova et al. Many materials have a well-characterized refractive index, but these indices depend strongly. Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in.
Refractive Index, Optical Constants, Extinction Coefficient of Polycarbonate, Lexan, Makrolon, PC for Thin Film Thickness Measurement. When eye safety is a concern, polycarbonate or Trivex lenses usually are the best choice. The perturbations in the atmosphere are a result of the refractive index not being exactly 1. Apec , from the standard Makrolon grades. Refractive index of Makrolon LED22as a function of temperature.
Refracting optical materials are specified by their refractive indices for a series of wavelengths. Such effects may be important in the case of refractive index measurements, photon correlation spectroscopy, and Raman spectroscopy. Polycarbonates and polythiourethanes are the most popular materials in use today, for optical applications. The refractive index of a basic plastic lens (CR-39) is 1. Polycarbonate lenses have a higher index of refraction (86) than CR-39 .
