Applications
Applicaton domains of residual scattering measurement are quite diversified and include ophtalmic optcs, semiconductor,
space industries :
- Control of polish / superpolish quality of mirrors and lenses
- Control of optcal glass quality
- Control of polished semiconductor surfaces (bare wafers, masks):
• surface quality
• presence of dust grains
- Measurement of scattering losses
