Laser-Induced Damage in Optical Materials
to note that this rather large relative uncertainty corresponds to an exceptionally high
absolute accuracy in determining scatter losses, in particular, for low-scattering sam-
ples such as superpolished surfaces and high-quality coatings. Another yet less-critical
issue is the mechanical accuracy of goniometric instruments that can be in the range
of0.01°, although the actual reproducibility as well as gravity-induced distortions of the
measurement arms has to be taken into consideration as well. Also, a certain part of
the backscattering hemisphere is usually not accessible because the detector head ...
