A glazed element, comprising: - a first glazing extending along a first surface, the first glazing having a first main face and a second main face, opposite the first face with respect to the first glazing, the first glazing comprising an opening, the opening defining an inner wall of the first glazing, extending along a thickness of the first glazing and defining a passage between the first face and the second face, the first glazing having a first coefficient a 1 of light absorption for a light ray having at least one wavelength chosen between 800 nm and 15 μm, - an infrared light transmission system mounted fixedly to the first glazing, the glazed element being characterized in that: - the infrared light transmission system comprises a support and a second glazing, the second glazing having a second coefficient a 2 of light absorption for a light ray having at least one wavelength chosen between 800 nm and 15 μm, the second coefficient a 2 being strictly lower than the first coefficient a 1, the support comprising a side wall at least partially covering the inner wall and extending from the second face towards the first face, the support comprising a flange mounted fixedly to the side wall and extending over the second face, the second glazing extending along the first surface and being embedded in the support, and surrounded by the side wall so that the support and the second glazing are in direct contact, the side wall being inserted into the opening so that the opening completely surrounds the side wall, the flange being fixedly mounted on the second face so as to seal off the first face from the second face. - a first glazing extending along a first surface, the first glazing having a first main face and a second main face, opposite the first face with respect to the first glazing, the first glazing comprising an opening, the opening defining an inner wall of the first glazing, extending along a thickness of the first glazing and defining a passage between the first face and the second face, the first glazing having a first coefficient a 1 of light absorption for a light ray having at least one wavelength chosen between 800 nm and 15 μm, - an infrared light transmission system mounted fixedly to the first glazing, the glazed element being characterized in that: - the infrared light transmission system comprises a support and - an infrared light transmission system mounted fixedly to the first glazing, the glazed element being characterized in that: - the infrared light transmission system comprises a support and a second glazing, the second glazing having a second coefficient a 2 of light absorption for a light ray having at least one wavelength chosen between 800 nm and 15 μm, the second coefficient a 2 being strictly lower than the first coefficient a 1, the support comprising a side wall at least partially covering the inner wall and extending from the second face towards the first face, the support comprising a flange mounted fixedly to the side wall and extending over the second face, the second glazing extending along the first surface and being embedded in the support, and surrounded by the side wall so that the support and the second glazing are in direct contact, the side wall being inserted into the opening so that the opening completely surrounds the side wall, the flange being fixedly mounted on the second face so as to seal off the first face from the second face. the support comprising a side wall at least partially covering the inner wall and extending from the second face towards the first face, the support comprising a flange mounted fixedly to the side wall and extending over the second face, the second glazing extending along the first surface and being embedded in the support, and surrounded by the side wall so that the support and the second glazing are in direct contact, the side wall being inserted into the opening so that the opening completely surrounds the side wall, the flange being fixedly mounted on the second face so as to seal off the first face from the second face.
