Abstract

Pantalla absorbente de radiación láser reflejada. Está estructurada en base a una chapa metálica (1) de cierto espesor que puede tener tamaño variable pero suficiente para cubrir todo el espacio a proteger de la radiación reflejada en la pieza (8) y que se mantendrá, mediante el soporte adecuado (2), en una posición fija y precisa respecto del cabezal o de la ventana de salida de la radiación láser (3) de modo que permita el paso del haz focalizado a través de un estrecho taladro (4) efectuado en la chapa. La superficie de la chapa expuesta a la radiación reflejada (5) tendrá un acabado superficial tal que le proporcione una alta absorción a la longitud de onda de la radiación láser incidente. Dispondrá de un sistema de refrigeración, con entrada y salida (6 y 7) que permita evacuar la energía absorbida y evitar la elevación excesiva de su temperatura.Absorbed reflected laser radiation screen. It is structured based on a metal sheet (1) of a certain thickness that can be variable in size but sufficient to cover all the space to be protected from the radiation reflected in the piece (8) and that will be maintained, by means of the appropriate support (2) , in a fixed and precise position with respect to the head or the laser radiation exit window (3) so as to allow the focused beam to pass through a narrow hole (4) made in the sheet. The surface of the sheet exposed to the reflected radiation (5) will have a surface finish such that it provides a high absorption at the wavelength of the incident laser radiation. It will have a cooling system, with inlet and outlet (6 and 7) that allows the absorbed energy to be evacuated and to avoid excessive temperature rise.
