Heptagon - Your Global Photonics Foundry

Wafer-Level-Optics (WLO)

By aligning with micro-optical design objectives, the company can design and fabricate master molds and perform high-precision imprinting on 6-inch or 8-inch POG (Polymer on Glass) wafer substrates. This scalable wafer-level process enables high-volume production of micro-nano optical components.

WLO Advantages: Full wafer-scale process for high volume mass production; UV curing, Low temperature, low pressure process; Conformal, microfluidic filling for micro/nano structures; Conformal reproduction of features less the 1µm; Reflowable optical material with high thermal performance.

Micro-lens Array (MLA)
Pattern generating micro-optics enable the projection of customized and precise light distributions across a variety of applications. In automotive projected lighting, they create bright, well-defined, and easily recognizable light patterns in the cabin or on the road. In environmental sensing, such as PM2.5 detection, micro-optical structures shape and control light for higher sensitivity and accuracy. Beyond these, they can also be applied in biomedical diagnostics, consumer electronics, and industrial inspection, where precise light control is essential.
Engineered Diffuser
Engineered Diffusers bring precision and scalability to next-generation 3D sensing and LiDAR systems. By shaping and homogenizing VCSEL emission into controlled divergence angles and beam profiles, they enable accurate depth sensing, secure facial recognition, in-cabin monitoring, AR/VR interactions, AI glasses and advanced machine vision. Designed for reliability and everyday integration, these compact polymer-on-glass components deliver consistent optical performance across consumer electronics, automotive, and industrial applications.
Diffractive Optical Element (DOE)
Imprinted Diffractive Optical Elements (DOEs) provide precise control of light in compact and cost-efficient formats, enabling advanced beam shaping and pattern generation across multiple industries. Produced with wafer-level imprinting on glass or polymer substrates, these DOEs deliver scalability and repeatability for high-volume applications. From laser beam splitting and homogenization to dot-pattern projection and AR/VR light management, imprinted DOEs empower next-generation sensing, display, and illumination systems with reliability and design flexibility.
