Aspectos destacados
- Fast, precise and easy-to-use measuring system for coating properties especially for ophthalmic anti-reflection and hard coatings
- The measurement can be done on the curved ophthalmic lenses directly without any special preparation of the backside. Front and backside can be measured individually
- No preparation of the backside surface necessary: Measuring probe rejects 100% of the backside surface reflections on ≥ 2mm substrates
- No roughening or blackening of the sample-backside needed for Features substrates with a thickness of ≥ 2mm
Características del proceso
Measuring of coating properties:
- Residual reflectance
- Color and color matching (dE-Lab)
- Layer thickness of hard coating (single and dual layer HC)
