Microcertec manufacture ceramic reflectors for lasers and IPL systems. We offer customized reflectors that are primarily manufactured from high-reflectivity alumina and subsequently glazed over in order to guarantee leak-tightness and protection. The base material - reflective alumina - was developed specificaly for this application. It offers a high reflectivity from visible to near infra-red. Reflectors are machined / ground against customer's drawing. Quantities range from prototype to production quantities. Glazing protects the surface in preventing adhesion of impurities and primarily ensures leak tightness of the reflectors. Compared to metal reflectors, ceramic units offer higher reflectivity and therefore enhanced laser power. They also have the advantage of being more resistant to temperature variations and erosion from cooling fluids, hence leading to extended operating life. Applications The following applications require ceramic reflectors in order to ensure a high...

Microelectronic circuits continuously require new packaging technologies. Ceramic substrates are widely used in this field for their good dimension stability, high electrical insulation as well as their resistance to high temperature. But it is now possible to create microelectronic circuits on 3D carriers made with ceramics. This new type of component integrates electrical and mechanical functions on a same carrier, which gives a wider scope in terms of design and integration. Microcertec has developped a unique expertise to manufacture these ceramic 3D interconnection devices - CI3D - based upon high-precision ceramic grinding of a 3D carrier, thin-film metallizing and laser etching. These 3D interconnect carriers demonstrate the advantages of being made with advanced ceramics but they also offer miniaturization capabilities, enhanced reliability and more simple integration stages. In actual fact, the geometry of the carriers offers a 3D arrangement so that microelectronic...
