Optical Modelling and Thin Film Stack Design
Fraunhofer FEP performs optical thin film stack modelling for
- designing a thin film stack towards a target transmission or reflection spectrum or color appearance
- elaborating optical properties of thin film stacks on various substrates (plastic, metal, glass) including the calculation of e.g.:
- transmission, reflection and absorption spectra,
- color and its angular dependence and color rendering index
- weighted transmission towards, e.g. the human eye response or absorption behavior of solar cells
Our optical design tools support single and multi layer systems and graded layers.
Applications include e.g.:
- Antireflection coatings or highly reflective systems
- optical filter: low-pass, high-pass, band-pass
- low-e and heat mirror coatings
- optimized encapsulation films and light-incoupling to solar cells
- decorative surfaces with specific color appeareance
- fraud protection and security labels
- tuning color rendering and appearance in smart windows
Deliverables
Input needed from customer
We need either the thin film stack and the target quantity to be calculated or
the target spectrum / optical properties and the materials to be used.
