Optical element having a coating for influencing heating radiation and optical arrangement

An optical element, comprising:

• a substrate having first and second sides;
• a first coating supported by the first side of the substrate;
• and
• a second coating supported by the second side of the substrate,
• wherein:
• the substrate comprises a glass;
• the first coating reflects EUV radiation;
• the second coating transmits radiation at a first wavelength;
• the second coating comprises a member selected from the group consisting of an absorbing layer that absorbs radiation having a second wavelength and a transmitting layer that transmits radiation having the second wavelength;
• the first wavelength is in a range selected from the group consisting of the visible range and the infrared range;
• the second wavelength is in a range selected from the group consisting of the visible range and the infrared range;
• the second wavelength is different from the first wavelength;
• and
• the optical element is an EUV mirror.
