Materials and coatings are of primary concern in the design of optical systems. Used to control the light path, they are essential to ensure the performance of lighting and imaging systems. Among other things, they allow for the control of stray light while ensuring quality visual renderings. Their characterization is essential to predict the performance of a complete system during its design. PISÉO’s optical engineers have first-rate skills and technical resources to make informed choices of optical materials.
The optical design of high-performance systems requires perfect mastery of the optical properties of materials.
A large percentage of the engineering projects conducted by PISÉO involves optical design. Our experts design systems that meet our customers’ most demanding requirements, then model and evaluate their performance using optical simulation software that integrates the materials’ optical properties. The skills and resources they mobilize allow them to consider a variety of materials and quickly offer their clients appropriate choices for their optical systems.

PISÉO’s optical engineers rely on a vast database of materials and their optical properties, including essential parameters such as transmittance, reflectance, and BRDF (Bidirectional Reflectance Distribution Function). This data is precisely integrated into our optical models, then used by our simulation software such as LightTools or Zemax to accurately predict the performance of the overall optical system.
The quality of optical data is fundamental in guaranteeing precise and reliable simulation results. Aware of this challenge, our experts pay particular attention to the selection, validation, and integration of this data. This rigor allows us to provide impeccable studies and designs to meet our customers’ requirements..
In-depth knowledge of the optical properties of materials is therefore essential to choosing the material best suited to each project.
PISÉO has its own optical testing laboratory, equipped to characterize the electro-optical performance of components and photonic systems. Our equipment also allows us to accurately measure specific properties (transmittance and reflectance) of materials used in optical systems regardless of their applications. Other properties, such as BRDF (Bidirectional Reflectance Distribution Function), essential for the simulation of diffusing materials, are measured at a partner laboratory under the control of PISÉO. Indeed, measuring the optical properties of materials requires great expertise in optical metrology and adequate technical means.
At PISÉO, our experts have mastered the selection and integration of materials to meet a wide variety of optical applications, including:
- High transmission materials to maximize luminous efficiency
- Light guides (Learn more)
- Stray light suppression (Learn more)
- Diffusion for uniform light distribution
For each project, we can offer you perfectly adapted materials for your optical systems, taking into account your technical needs, industrial constraints, and the regulatory requirements specific to your application.
Whether it is to develop precision optical systems, guarantee maximum luminous efficiency, or meet strict performance and safety standards, PISÉO is committed to providing you with tailor-made and optimal solutions.
