This is an ARRI Half Single Scrim that fits the Fresnel 150 or any fixture that accepts a 3" 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.
