Source Assembly

  1. Sandwich two sections of lighting grid together and carefully align them so that each opening forms a clear cell 1/2" x 1/2" x 1" deep.
  2. If you will be mounting this collimating grid with the square cells parallel to the axes of the tube lamps (as shown), position the top of the sandwich 2.5" (6.4 cm) from the edges of the reflectors. This location will insure that Moiré fringes do not impair the uniformity of illumination at the copy board, 13.5" (34.3 cm) from the bottom of the grid.

    Rotating the grid so that the rows of cells form an angle of 30° to 45° with the tube axes will eliminate MoirÉ fringes altogether and allow to collimating grid and copy board to be positioned wherever is most convenient. However, trying to cut the fragile grid material on an angle will significantly increase the difficulty of fabrication.
