For 3D sensor technology, MLA-based light projectors are used to create light patterns on objects. Typical applications are e.g. face or component recognition. temicon offers MLA based light projectors in a variety of lens geometries and chip designs which can also be retrofitted into existing sensors.
The temicon microlens arrays are produced via a combination between lithography- and reflow processes. Different spherical lenses within wide parameter range for lens radius, -height and -arrangement can be realized.
The unique temicon technology allows the production of MLAs in a gapless format, i.e. without spaces between the single lenses. MLAs are available with different arrangements such as hexagonal, linear, square, rectangular or with stochastic distribution.
