Optical Surfaces - Newport

Optical Surfaces. The lens application drives the requirements for surface irregularity and surface quality. When preservation of wavefront is critical, λ/4 to λ/8 irregularity should be selected; when wavefront is not as important as cost, λ/2 irregularity can be used. For surface quality, the tighter the scratch-dig specification the lower ...
