The first versions of OptiLayer were developed for DOS operation system. Currently, OptiLayer utilizes the most up-to-date software decisions and has mathematical kernel designed on the highest professional level.

The founders have many years experience in thin film optics and developing models and algorithms for the analysis, design, and characterization of thin films and thin film optical coatings.

OptiLayer became successful due to:

- Theoretical expertise of the founders in physics, mathematics, mathematical modeling, optimization theory
- Experience in software development
- Participation of the founders in several international projects connected with experimental investigation of thin films and optical coatings produced by various deposition techniques

OptiLayer thin film software consists of three modules: OptiLayer (design, evaluation, monitoring, sinultions), OptiChar (optical characterization of single layers), and OptiRE (post-production characterization and reverse engineering of multilayer coatings). All modules are compatible on the database level and can easily exchange data. This is the only thin film software that uses threaded computations. This allows you to interact with the software without interrupting computations and to obtain all other benefits of the modern Windows environment.
