Device for determining the effective superficial roughness of polished optical samples by measurement of integral light scatterings

摘要

device for measuring the integral streulichtes of polished glasproben by ulbricht ball. this bullet is on its inner side with an ideal disseminated material coated and has the opposite strahleintrittsu00adu00f6ffnung sample and a strahlaustrittsu00f6ffnung for the reflected beam.the ball also has a detector in the kugelwandung arranged for the new oversight. the probenu00adtru00e4ger is in the direction of the incident spray with an opening and towards the back of the sample under strahu00adles behind this opening with a trap by mistake.for the sample of the sample is a abdeckblende with an opening for the incident beam and the sample surface to the refleku00adtierten beam are provided. this abdeckblende is, at least in the area of the probenru00fcckseite reflected jet with a trap or marked as trap trained.
