Vacuum deposition coatings

Posted by Luxexcel on Mar 4, 2016 3:04:35 PM

Vacuum deposition coatings concern a process where solid metal gets evaporated on the to be coated component. By performing this process under vacuum, the evaporation is not just better controlled but also the process temperature is lowered, which allows plastics to be coated. This technique is used to coat for example mirrors.

Concentrated photovoltaics (CPV)

Posted by Luxexcel on Jan 13, 2015 1:47:00 PM

Concentrated photovoltaics (CPV) is a photovoltaic technology that generates electricity from sunlight. Contrary to conventional photovoltaic systems, it uses lenses and curved mirrors to focus sunlight onto small, but highly efficient, multi-junction (MJ) solar cells. Despite the need for additional concentrating optics, and the usage of more expensive MJ-cells, CPV systems, and especially High concentrating photovoltaic (HCPV) systems, have the potential to become competitive in the near future. They possess the highest efficiency of all existing PV technologies. And a smaller photovoltaic array also reduces the balance of system costs. CPV systems often use solar trackers and sometimes a cooling system to further increase their efficiency. They are currently more expensive and far less common than conventional PV systems. However, ongoing research and development is rapidly improving their competitiveness.

Smooth transparent 3D printing: impossible or not?

Posted by Luxexcel on Dec 16, 2014 10:54:00 AM

3D printing is extremely popular these days. Everyday new products, which are printed, are presented throughout different industries. From a table in your house to customized clothing, almost everything can be 3D printed. With this 3rd manufacturing revolution, 3D printing applications for business to business markets arise. However, there are some issues with regular 3D printing methods. With the most standard 3D printers it is inevitable that you will see layers on the end product. Transparent 3D printing is quite hard without layering. For 3D printed optics a traditional printer cannot be used. At Luxexcel we developed a unique printing technique which makes transparent 3D printing possible without visible layering.
