This is a used ARRI Full Single Scrim that fits the 1K Fresnel, Arrisun 5 PAR, Compact HMI 575W, or any fixture that accepts a 7.75" accessory.
Scrims are metal screens mounted in a metal frame. They are placed in front of a light to reduce light intensity.
ARRI makes 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.
