Specifications: Figure and Finish are not Enough (ABSTRACT)
ABSTRACT: A paper that shows why simply specifying figure and rms surface roughness is not enough information to assure a finished optic will perform as expected. Mid-spatial frequency roughness must also be specified. There are examples using the PSM to show the effects of mid-spatial frequency roughness, and examples of using the structure function to characterize mid-spatial frequency roughness.
