Arri 650W Fresnel Scrims are metal screens mounted in a metal frame. They are placed in front of a light to reduce light intensity.
- Full Single: This scrim covers the entire lightface and reduces the intensity of the entire light beam.
- Half Single Scrim - this scrim only covers half of the lightface reducing half of the light intensity.
- Half Double: This scrim is the same as the half single but reduces light intensity twice as much.
