Abstract
The present invention relates to a heat filter and a process for manufacturing this filter. This heat filter may for example be used to filter surgical or examination lighting composed of a light source which emits energy, or radiation, in the visible and infrared ranges. It allows the light emitted by this source to be filtered so as to prevent infrared radiation from hindering the surgical team or the patient. It includes a substrate, at least one layer of an infrared reflecting material, and a coating forming an interference filter in the visible range. The invention process includes the deposition on a substrate of a layer of an infrared reflecting material and the deposition on this layer of an interference filter in the visible range.
