LIMBAK team has about 30 years experience in advance optical design, both using propietary methods and commercial optimization software. Along the years, LIMBAK has been able to reduce to practice several patented technologies, now in Limbak's IP portfolio, and has also supported brands worldwide to address complex optical design tasks, often linked to free-form problems, where asymmetric performance and/or tight off-axis dimensional constraints made the task very hard for conventional architectures.

The average LIMBAK design is very compact (reduced size) thanks to the usage of light folding (reflection and total internal reflection optical paths, combined with refractive surfaces), multi-channel (splitting the light into parallel paths, emulating the eyes of insetcs) and comprises free-form surfaces. However, Limbak's know-how can also be applied to more conventional rotationally symmetric optical trains.

Since optics apply transversally yo many fields, the team has been able to produce designs in for several applications, including VR/AR/MR, illumination, solar energy, automotive lighting, camera optics, etc.

Limbak can design all types of optical systems, comprising free-form mirrors and lenses, TIR surfaces, but also rotationally or linearly symmetric optics. Multi-channel optics, including mini-lens arrays, light-folding compact architectures, such as pancake lenses are also in the design portfolio. Limbak works with a set of design constraints and performance goals fixed by customers and delivers solutions in the form of CAD files, analytical description of surfaces and full ray trace models
