Although glass was the only lens material for over
600 years, today plastic lenses used for prescription
eyewear and sunglasses requiring high abrasion
resistance and high quality optical properties have
been developed. High index plastic lenses are a new
lens category, having refractive index from 1.54 to
1.71. Recently, much interest has been shown in new
high index polymeric materials. Main target is lenses
with good optical performance; high refractive index,
low constringence, good light transmission and UV
absorption. Outstanding factors defining this
performance are refractive index and chromatic
aberration. This book, therefore, provides
measurements of refractive index using a light source
or a laser beam and computing the minimum deviation
angle through a prism of the material, chromatic
aberration determined by evaluating the optical
performance of the material itself. It should be
especially useful to professionals in industrial,
educational and marketing fields, or anyone else who
may be interesting in measurement techniques,
properties or performance of new optical materials
