1.Optical design is highly application-driven –It is important to clarify the targets/goals of design 2.Optical design is an engineering issue –Specification is most critical toward the success •It is important to have a list of performance request
Projection lens is a kind of lens which transfer an image from one place to another –Magnification is generally required •Generally, projection lens is required to –Achieve sufficiently-bright image •In this case, optical throughput is key issue –Ko
