OSLO (Optics Software for Layout and Optimization) is a powerful optical design program with the scope needed to meet today’s optical design requirements.

In addition to classical lens design features, it combines advanced ray tracing, analysis, and optimization methods with a high-speed macro language to solve a wide variety of new problems in optical design.

What Does OSLO Do?

It is primarily used in lens design to determine the optimal sizes and shapes of the components in optical systems. It has the capability of modeling a wide range of reflective, refractive and diffractive components. In addition, it is used to simulate and analyze the performance of optical systems. With it’s CCL programming language, you can develop specialized design and analysis software tools for modeling, testing, and manufacturing optical systems.

It provides an integrated software environment that helps you complete almost any task in contemporary optical design. More than a lens design program, it also provides advanced tools for designing medical instrumentation, illumination, aerospace and defense systems as well as telecommunications equipment.

Why is OSLO the Technology Leader?

It was the first software to demonstrate that serious optical lens design could be carried out using desktop computers. Today, it has been accepted as a standard tool by companies throughout the world that use it to create better, lower-cost designs and manufacture them more efficiently. 

But optical design today goes far beyond the range of problems handled in the past. Now, optical systems are integrated with electronics and image processing software creating new design alternatives. OSLO’s technological leadership in optical design software is more valuable today than ever before.

How do I download the free OSLO EDU edition?

Our professional optical design software is called OSLO Premium. A free edition (OSLO EDU) is available in the Education section but is limited to 10 surfaces.

OSLO works seamlessly with our TracePro software to provide a complete and comprehensive design environment.
