Products. SUSS MicroOptics manufactures custom monolithic micro-optics at wafer level in silicon and fused silica by using reactive ion etching (RIE) to transfer the required structures to the substrate.

With the help of CAD/CAM technology, convex micro lens array on convex spherical surface with different scales on material of polyvinyl chloride (PVC) and pure copper is fabricated using micro tungsten carbide ball end milling tool based on the ultra-precision micro-milling machine.

The micro-lenses offer a long focal depth, which means that an array can project a focused image on to a parallel, slanted or curved surface. Micro-lens arrays may be configured to provide a bright output in an extremely low-profile form factor.

such as fly-cutting, micro milling, grooving, and fast tool servo (FTS) are more suitable for micro optical structure fabrication. In this study we focus on the micro lens array fabrication using FTS. In general, the micro lens array consists of spherical lenses and could .

Jan 02, 2014 · Ultra precision machining using micro size diamond cutters can be used to create true 3D optics with relatively easy setup and fast turnaround. Micro milling and grinding technologies can be used for the production of plano, spherical, aspheric, conformal, and freeform optics.

Microlens arrays with superior form accuracy are used for applications, where reliability and highest efficiency are crucial criteria. They range from beam transformation for fiber coupling over the homogenization of laser light up to the efficient combination of laser stacks of identical wavelength.
