Patent ID: 11203038

Abstract:
The present invention relates to a curing device for applying UV radiation to substrates, comprising at least one radiation source, at least one reflector member surrounding the radiation source, at least two divided dichroic mirror members opposite to the radiation source, which largely transmit the VIS & IR content of the radiation source and keep it away from the processing zone and at the same time largely reflect the UV content of the radiation source in the direction of the processing zone, at least one optical disk member that separates the cooling gas flow in the exposure device from the processing zone, and which is characterized in that the at least two divided dichroic mirror members are arranged in such a manner that they are separate from one another and offset from one another in the direction of the main beam and are displaced parallel to the main beam and thus opaque to the main beam, so that cooling gas can flow out through the openings created, but intensity loss of the UV radiation does not occur.
