This is an ARRI Half Double Scrim for the Arrilite 650, 1000, or any other fixture that accepts a 7 1/4" accessory. Scrims are metal screens mounted in a metal frame. They are placed in front of a light to reduce light intensity.

There are four different types of scrims:

• Full Single: This scrim covers the entire lightface and reduces the intensity of the entire light beam.
• Full Double: This scrim covers the whole face of the light. It has two metal screens in it, reducing light intensity by two times the amount of the full single.
• Half Single: 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.
