Martin VDO Fatron Square Diffuser, 320 mm
Martin supplies the Square Diffuser as standard with each VDO Fatron, so this is the front a fixture normally arrives with and the one a rental stock runs short of first. It squares off the face of the wide-body batten and blends the pixel row, which keeps butted runs reading as one straight unbroken line of light.
The smoked version is the same shape in a darker material for positions where the fixture itself is in shot. Both are stocked here in 320 mm; the 1000 mm equivalents are P/N 91611818 and 91611820. Fronts clip on by hand and are common across the VDO Fatron optical range, but they are not shared with the VDO Sceptron, which has its own part numbers.
