Abstract
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.

An installation for increasing the usable range along the axial direction of a light source, comprising:
- a light source for generating a sense image;
- and
- an optical sensor, wherein the optical sensor includes a sensor, a transparent panel and a coating, wherein the transparent panel is positioned between the sensor and the light source, the coating is formed over the transparent panel, the transparent panel has a long axis running from edge to edge, the sensor detects an image after light from the light source has passed through the coating and the transparent panel, and the coating on the transparent panel modifies the light transparency along the long axis such that the light transparency is lower in the middle compared with the ends.
