WebCR-39 which stands for Columbia resin #39 is the most commonly used plastic polymer lens material. The lenses block 80% of ultraviolet light without treatment, and can be tinted and coated to provide further ultraviolet light blocking. Plastic lenses tend to have a lower index of refraction, which require thicker lenses. WebThe refractive index of the medium can be calculated using the formula: n = c/v. Substituting the values in the equation, we get. n = 3 × 10 8 m/s/1.5 × 10 8 m/s = 2. The refractive index of the medium is 2. The speed of light in an unknown medium is 1.76 × 10 8 m/s. Calculate the refractive index of the medium. WebHigh-transparency polymers, called optical polymers (OPs), are used in many thin-film devices, for which the knowledge of film thickness (h) and refractive index (n) is generally required.
