The ARRI Ground Glass 16:9, Spherical, 800 is compatible with ALEXA Studio and ALEXA XR/XT/SXR/SXT Studio cameras. This ground glass shares the same physical dimensions as its ARRICAM film-camera ground glass cousins, but is precisely aligned with the different ALEXA frame lines.
The 800-grit ground glass is the standard grind used in ARRI cameras, enabling easier focusing than the brighter 1200 grind. This ground glass includes1.78:1 and 2.39:1 (flat) rectangular frame lines with 1.33:1 marked as stubs inside the 1.78:1 lines.
