The framing shutter system includes an aperture that is configured to receive the light beam. The framing shutter system further includes a plurality of shutter blades configured to be positioned across the aperture and mask a portion of the light beam. Each of the shutter blades includes a blade substrate material having a front surface that is configured to receive the light beam and a rear surface on an opposite side of the blade substrate material from the front surface. The front surface of each shutter blade includes a first coating that is configured to reflect one or both of light and heat. The rear surface of each shutter blade may include a second coating configured to reduce reflection of light from the rear surface.
