KALEIDO TECHNOLOGY

Kaleido is developing wafer level optics for production of small lenses mainly for the mobile phone market. The company is doing only R&D and not actual production and thus does not have any large-scale automated production facilities. Kaleido Technology is currently maturing the technology for large-scale production and, therefore, focusing on stabilizing the manufacturing and minimizing manual assistance in the process. The main aim has been to implement in-line checks of the tooling quality and the definition of strategies for the avoidance of defective geometries. Defined test-cases Concerning the manufacturing processes from Kaleido Technology, two test-cases have been defined for their analysis within the project. They are related to the manufacturing of lens replication moulds on different materials as tungsten carbide and non-ferrous metals by precision grinding and diamond milling. This way, the work carried out has been divided into two main groups: one relative to the own manufacturing process and its control, the second one focused on the characterization of the manufactured optical devices. Related to these test-cases, different working groups have been assembled in order to define and develop solutions for the different problems defined by the industrial end-user. Next, the different test-cases and the tasks related to their solution are exposed briefly. Figure 34 shows a poster summarizing visually the technical work carried out during the project related to the test-cases from Kaleido Technology.
