OPTICAL MODULE COMPRISING AN IMAGE SENSOR AND A LENS UNIT THAT IS SUPPORTED ON THE SENSITIVE SURFACE OF THE IMAGE SENSOR

摘要

Disclosed is an optical module comprising a lens holder (14) into which a lens array consisting of three lenses (16, 18, 20) and a diaphragm (21), for example, is inserted. Preferably, the lenses (16, 18, 20), and optionally the diaphragm (21), are clearly oriented by means of the geometrical shape thereof such that no further optical adjustment is required while the lens array (14; 16, 18, 20; 21) is disposed in a supported manner directly on the sensitive surface (34) of the semiconductor element (12). The invention is based on the fact that a camera module can be designed which dispenses with the need to mechanically adjust the focus in any manner by supporting especially the lens holder or the lens (16) or the peripheral area thereof directly on the chip surface (34). The invention is particularly suitable for applications in the interior or exterior zone of a motor vehicle.
