摘要:
A test mask 1 for microscopy is disclosed, which is formed on a substrate of quartz. The test mask 1 comprises a multiplicity of sub-masks 4, which are implemented such that each sub-mask 4 comprises structures which differ within a sub-mask 4 with regard to form and size. In addition, the structures of the individual sub-masks 4 are designed for optical or particle optical measurements according to size.
