More light!

Together with two industrical partners, the Fraunhofer IPT has developed a high-power-LED lighting system, which combines both small dimensions and very high light performance.

Injection-molded plastic lenses

From design to serial production

Injection molding allows for a cost-efficient production of highly precise plastic lenses. However, before series production is possible, an entire process chain must be completed: from lens design and manufacturing the injection molding tool to producing the prototype. A high degree of development competence is required, particularly in the lighting industry, which needs design freedom for creating lighting solutions, and medical technology, which requires precision nanostructure production.

The Fraunhofer IPT is one of the few manufacturers capable of producing high-precision plastic lenses using injection molding processes. The customer-specific products developed in our facilities, ranging from lighting design to finished lenses, meet the necessary requirements and are highly precise: We combine our interdisciplinary competences in lens and component design, high-tech tool and mold making, illustrating replication processes, and specialized system montage. We thus fulfill both quality and economic requirements with highly developed processes and a wealth of experience.

Application examples

LED Lighting

Attachment lenses as well as optical systems and modules for many lighting applications: hall and workplace lighting, production and warehouse lighting, street and public lighting, and much more.

Microlenses

Plastic microlens systems are used increasingly often in camera systems and endoscopes as well as in many sensor technologies. Therefore, high-precision manufacturing and reproducible quality are particularly important for a high-performance imaging system.

Polymer lenses

Our development and manufacturing portfolio includes lens arrays, diffractive and refractive lenses, and freeform lenses, as well as spherical and aspherical lenses.

Life Sciences and
medical technology

In addition to optical components for medical-technical lighting and analytic systems, the principal focus of our development work is on plastic lab-on-a-chip diagnostics systems.

Automotive

The design, simulation and finally production of structured light guides and their respective components for exterior and interior lighting (edge lighting and ambient lighting) is a core competence of the Fraunhofer IPT.

Injection-molded
silicon arrays

Using highly transparent liquid silicon rubber (LSR), we create attachment lenses for demanding applications that require highly heat-resistant components, e.g. automobile headlights or large-surface silicon lens arrays.
