The ARRI Ground Glass 4:3, Blank, 1200 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 1200-grit ground glass is brighter than the standard 800-grit ARRI ground glasses but is also more difficult to use when focusing. This ground glass is blank and does not include any frame line marks.
