Apparatus for determining the effective surface roughness of polished optical samples, by measuring the total integrated scattering, only operates for non-light-transmissive samples. For a transmissive sample, the invention adds a light trap behind the sample for transmitted light, and a diaphragm in front of the sample. The rear surface of the diaphragm is provided with a non-reflective wafing which traps secondary light reflected or scattered by the inside rear surface of the sample.

Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
