Optimask drives the study and the development of thin films in the spectral range from 175nm to 3300nm.

Our coating plants, our engineering softwares, our lab-spectrometers and our know-how are available for all types of coatings :

- Single and multilayers antireflective stacks
- Maximal Reflectance systems
- Edge filters
- Dichroic filters
- Cold Mirrors
- High-pass and low-pass filters
- Beam splitters

The performances of the coatings are achievable for a wide range of incidences (from 20° to 70°).

We can provide a spectrum plot for each product from our VARIAN CARY 5000 (UV-VIS-NIR) and our Nicolet MAGNA-IR 560 (under 0 or 45° incidence) a spectrum plot for each product.
