Although glass was the only lens material for over600 years, today plastic lenses used for prescriptioneyewear and sunglasses requiring high abrasionresistance and high quality optical properties havebeen developed. High index plastic lenses are a newlens category, having refractive index from 1.54 to1.71. Recently, much interest has been shown in newhigh index polymeric materials. Main target is lenseswith good optical performance; high refractive index,low constringence, good light transmission and UVabsorption. Outstanding factors defining thisperformance are refractive index and chromaticaberration. This book, therefore, providesmeasurements of refractive index using a light sourceor a laser beam and computing the minimum deviationangle through a prism of the material, chromaticaberration determined by evaluating the opticalperformance of the material itself. It should beespecially useful to professionals in industrial,educational and marketing fields, or anyone else whomay be interesting in measurement techniques,properties or performance of new optical materials
