M. Kopecky et al., SURFACE FINISHING BY LACQUER-COATING TECHNIQUE, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 395(2), 1997, pp. 281-286
A series of optically flat glass substrates with microroughness of a f
ew nanometers prepared by standard mechanical polishing has been cover
ed with acrylic lacquer coatings. The influence of lacquer concentrati
on on the surface finish has been investigated by using X-ray reflecto
metry and optical interferometry, The surface microroughness of about
0.6 nm with simultaneous preservation of the underlying optical figure
may be achieved in the case of optimal lacquer concentration.
