A mask frame support unit includes a case, a protruding body extending below the case, and a station having a flat head disposed above the case. The protruding body includes a tapered region and a cylindrical region. The tapered region includes a first end having a first diameter coupled to the case and comprising a second end having a second diameter opposite the first end. The second diameter is less than the first diameter, and the tapered region is coupled to the cylindrical region at the second end. The case houses a number of components including an upper receiving plate in contact with the station, a lower receiving plate disposed underneath the upper receiving plate, a flat head unit movement support mechanism disposed between the lower receiving plate and the body, and a centering component.

A diffuser includes a front-side gradient surface formed from a diffuser block, a back-side gradient surface formed from the diffuser block, and opening structures formed from the front-side gradient surface to the back-side gradient surface. Each opening structure includes a conical opening having a first end along the front-side gradient surface and a second end corresponding to an apex at a depth within the diffuser block, and a cylindrical opening formed from the depth to the back-side gradient surface. The opening structures are arranged in rows including a first set of rows and a second set of rows alternately positioned along a length of the diffuser block.
