What is optical design ?

Optical design is the process of designing and developing optical systems. In this process, an optical engineer considers many physical factors. These include spectral distribution of light, photometry, colorimetry, optical properties of materials, spectral response of illuminated bodies and geometry of components. An engineer also considers constraints and objectives related to the intended use.

Optical design is a multidisciplinary subject that requires a thorough knowledge of both mathematics and physics, as well as a great deal of experience. It also requires a good ability to understand the needs of the application for which the system is intended.

The design process begins with the determination of the optical performance to be achieved according to the intended use. These depend on the type of system considered and the applications, whether it is lighting, imaging, or display. Depending on the systems, we will therefore specify details including illumination, luminance, uniformity, contrast, color temperature, focal length, field of vision, spot dimension and spatial frequency.

Subsequently, the optical engineer will endeavor to imagine and evaluate optical systems to meet the objectives set. For this, they will perform sizing calculations, numerically model the solutions envisaged and simulate their performance using appropriate tools. This operation can be repeated as many times as necessary until they get an optical system capable of meeting the fixed performance requirements.

At the end of this work, they provide details of the various optical components created, integrating all the mechanical interfaces, taking into account the tolerances linked to manufacturing and assembly. Finally, the experts will prototype and test the system using appropriate optical measurement equipment.

Optical design comes into play in many industrial areas including lighting, automotive and transportation, defense, space, medical, manufacturing, photography, and more.

PISÉO’s definition of optical design

PISÉO understands optical design in a broad way. The optical system is considered as an assembly that integrates opto-mechanical and opto-electronic components, or even software. Indeed, only an overall system approach that considers all the parameters involved makes it possible to achieve an optimized design that will be able to meet the project objectives in all respects. In this way, our optical design work considers the application needs for ultraviolet (UV), visible (VIS) and infrared (IR) radiation. It considers the physical and economic characteristics of photonic components such as Light Emitting Diodes (LEDs), lasers, photodiodes, imaging sensors, materials for optics and surface treatments, as well as environmental and industrial constraints. In addition, we benefit from the close links with Yole Group analysts, who permanently watch photonic technologies, guaranteeing customers solutions at the cutting edge of progress.

Why entrust your optical design to PISÉO experts?

Coming from large groups and Small and Medium Enterprise (SME) leaders in their fields, PISÉO’s experts have extensive industrial experience in the design and manufacture of optical systems. With great rigor, they put their know-how at the service of our customers.

The numerous research and development projects carried out in all fields constantly develop our experts’ knowledge. They also rely on their cutting-edge technical resources including proprietary calculation and analysis tools, design, and simulation assistance software such as Zemax, LightTools and Rhino, and an accredited test laboratory. The latter allows them to precisely characterize the optical performance of the photonic components selected and of the systems designed by them from model to prototype to finished product.

PISÉO experts have a unique combination of know-how and technical means. They are thus able to support your company’s development by designing and industrializing, in a rapid and reliable manner, simple or complex optimized optical systems in response to all your needs.

After over 10 years in existence, PISÉO’s innovation platform has supported many customers globally in their industrial optical system projects. Examples include a high-power infrared illuminator for an industrial specialist in surveillance, endoscope imaging for a world leader in medical systems, redesign of a lens for a lighting SME and redesign of a light guide for an automotive player.

]]> Thanks to their involvement in the various standardization committees of AFNOR, CENELEC, and IEC, PISÉO experts participate in the drafting of standards and analysis of international regulations and standards. They thus have in-depth and exhaustive knowledge of this field.

Compliance with standards constitutes a solid basis for ensuring product compliance with the requirements of various international regulations and is an essential prerequisite for marketing products.

Designers, manufacturers, and marketers of products with high optical content can rely on PISÉO to guarantee the conformity of the devices they develop and market.

Regulations and standards compliance

With their experience in the design and development of optical-photonic systems  and their ISO 17025 accredited laboratory (scope available on www.cofrac.fr), PISÉO experts can advise you on the standards that apply to you and carry out the corresponding tests.

In the medical field, for example, PISÉO regularly supports customers to demonstrate the compliance of products (endoscopes, AR/VR systems) with the requirements of the FDA (Food and Drug Administration) in the USA. This support involves analyzing the requirements, proposing an optical performance and safety test protocol, and conducting the tests in our accredited laboratory. At the end of the tests, customers are provided with independent and impartial reports recognized by the FDA.

Product performance

The energy transition requires unprecedented improvement in product performance, and regulations in this area are becoming increasingly restrictive. This is particularly true for lighting, where there are European regulations on eco-design and product marking relating to performance ((EU) 2019/2015 and (EU) 2019/2020), as well as numerous harmonized standards (IEC 62722-1, IEC 62722-1, IEC 62031, etc.).

In the field, PISÉO experts participate in the work of the AFNOR UF 34 commission.

Optical product safety

Products producing light radiation are subject to optical safety regulations, including, but not restricted to, eye safety. LED or LASER-type light sources that emit UV, visible, or IR can, depending on their characteristics (spectrum, power, density), have a deleterious effect on users (see our article on this subject: Risks optics).
PISÉO experts are particularly committed to the prevention of optical risks. They participate in the work of the AFNOR UF76 standardization commission and the National Commission for Optical and LASER Safety (ConSOL) under the aegis of Photonics France.

PISÉO thus ensures the optical safety of photobiological and LASER risk tests carried out within their laboratory and can advise you on determining the optical risk group of your lighting systems, as well as the class of your LASER.

Drawing on this expertise and their technical resources, PISÉO experts can also define and implement solutions to prevent user exposure to optical risks. This concerns the products and optical test benches developed by PISÉO, as well as risky situations on customer sites.

Like our many satisfied customers, you can trust the regulatory and normative analyses of PISÉO experts to ensure that your products comply with current international norms and standards.
