  • Patent number: 11554563
    Abstract: The method regards manufacturing devices by replication, wherein each of the devices comprises a device surface. The method comprises producing the devices from a replication material by replication using a replication tool (1), wherein the replication tool (1) comprises a tool material comprising replication sites (4) comprising a replication surface (5) each. Each of the replication surfaces (5) corresponds to a negative of the device surface of a respective one of the devices. The tool material comprises, in addition to the replication sites, one or more mitigating features (7) for reducing asymmetric form errors of the device surfaces. Replication tools (1) and methods for manufacturing these are also described.

  • Patent number: 11422291
    Abstract: The method for manufacturing a multitude of devices comprises: providing a replication tool comprising a tool material; conditioning the replication tool, wherein the conditioning comprises applying a treatment to the tool material, wherein the treatment comprises exposing the tool material to a conditioning material. And it further comprises, after the conditioning: carrying out one or more replication processes, wherein in each of the one or more replication processes, one or more of the devices are produced from a replication material by replication using the replication tool. The treatment can comprise dimensionally changing the tool material by the exposure of the tool material to the conditioning material. Before carrying out the replication processes, the conditioning material can be hardened and removed.

  • Patent number: 10302863
    Abstract: The present disclosure describes methods of attaching surfaces together. In one aspect, a method includes depositing a first adhesive onto a first surface of a first item, the first adhesive forming a pattern that at least partially surrounds a region of the first surface where there is no first adhesive. A second adhesive is jetted onto the region of the first surface, wherein the second adhesive has a viscosity lower than a viscosity of the first adhesive. The first surface of the first item and a second surface of a second item are brought into contact with one another. The method also includes curing the first and second adhesives. While the methods can be particularly suitable for manufacturing optical light guide elements, the methods also can be used in other contexts and applications as well.

  • Publication number: 20070131276
    Abstract: The current invention provides for the manufacture of solar voltaic cells with high sunlight to electricity conversion efficiencies by using improved silver-alloy thin films with a thickness in the range of 30 to 60 as a back reflector/conductor. The back reflector surface may be smooth or roughened depending on the design of the solar voltaic cell and the reflective surface used.
