ARRI 531651 6.625-inch Half Single Scrim
Scrims are metal screens mounted in a metal frame. They are placed in front o f a light to reduce light intensity. Arri makes four different types of scrims. Full single- this scrim covers the entire lightface and reduces the inten sity of the entire light beam. Full double- again this scrim covers the w hole 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 beams intensity. Half double- same as the half single but reduces light intensity twice as much as the half single.
