<p>An amorphous diamond coating applied onto mirrored optics in an Infrared motion sensor to block specific wavelengths of energy from a 'white light' source like a halogen lamp, without reducing the reflectivity of the mirror surface in the Mid-Infrared wavelengths. A specific thickness of diamond-like-coating is applied on top of the reflective metal surface of a mirrored part, thereby reducing the mirror's reflectivity at visible and near-Infrared wavelengths known to be problematic for IR motion sensors, such as those emitted from halogen lamps. The coating has no significant detrimental effect on mid-Infrared reflectivity, so the IR motion sensor's performance is otherwise unaffected.</p> |
