An installation for increasing the usable range along the axial direction of a light source. The installation has a light source and an optical sensor. The light source generates a sense image. The optical sensor further has a sensor and a transparent panel. The sensor is responsible for detecting the image generated by the light source so that a sense image is created. The transparent panel is positioned between the sensor and the light source. A coating on the transparent panel modifies the light transparency along the axial direction of the light source such that light transparency is lower in the middle compared with the ends.
