Manufacture of moulds for the production of very small-sized lenses

Production in series, both of optical components and of components with optical quality surfaces, whether very small-sized or micro-sized (from tenths of microns to half a millimeter) has acquired an important relevance in the fields of optics and laser within the growing framework of miniaturisation.

Thus, IK4-TEKNIKER is committed to the design and manufacture of moulds for the production of polymer microcomponents using microinjection and of optical quality, making moulds/inserts with optical quality (specular) surfaces, involving micro-sized features (for example, Fresnel lenses), by means of diamond-tipped lathe turning and micromilling.

As a result, aluminium inserts have been manufactured with surfaces of roughness in the order of a few nanometers using lathe turning with diamond-tipped tools for applications such as ocular lenses. This type of development has a special impact on biomedical applications, optoelectronics (sensors), laser components, etc. with specular surfaces for optical applications.
