Description
Book SynopsisDeals with the infrared zoom lenses. This title includes 18 refractive and reflective infrared zoom systems, bringing the total number of infrared zoom optical systems to 41 systems. It covers topics that include the importance of principal planes, athermalization by means of computer glass substitution, and global optimization of zoom lenses.
